:iagree: yup, your are right, trying to do that with Assetto Corsa, I have a sim coach I work with 1-on-1 and he started saying that too me recently. going to be another learning experience. Thanks for your input |
The better your sims peddle box is the better it will translate to your car. It is pretty fun and takes some learning to get trail braking down but you can't go fast if you don't know how. Also learning to left foot brake. It is not a thing for everyone but it has become automatic on the sim for me and I am incorporating it more on the track. It happens some time and it is unconscious and when I realize what happened I am like wtf and then smile and say I need to do that again!
The other thing it really helps with is getting comfortable with slip angle. Got to be comfortable letting the car four-wheel slide or drift through fast corners! Sent from my SM-G965U using Tapatalk |
Took the Z to SCCA Track night on Wednesday, more on that later...
The Z still gets noticed... -- individual comment on the car and talked about it -- driving in Atlanta and a person shout nice car next to me (he was in a BMW 328) -- person on a motorcycle passed me and gave me a thumbs up... Always nice to get comments on the car... :happydance: |
already a week ago, that I did scca track night at Atlanta Motorsport Park.
Did improve my time by .17, now down to a 1.43.74, slowly but steadily. I think I can get better, but it will come down to braking, also it was hot and slippery, so on the last run I dropped my tire pressure down a pound all around. I normal run my Michelin PS4 at 36 front and 34 back The Garmin Catalyst gave me a surprise, there was the usually comment, nice apex, good turn in early. so at least I get some feedback.. But the surprise I got was the comments between turns 15 and 16.. It said push harder I was like what, not once but several times... As I mentioned previous, I work with a coach out of England, so we reviewed my best lap https://www.youtube.com/watch?v=buEIT89g5_Q (I turned off the mike no sound) He said my lines were looking good and we worked on a few tweaks. Which I get to try at the end of the month. Going back for a full track day. I also had a photographer take some photos on track https://photos.app.goo.gl/GmoyqvQA1fEKuEUf8 https://photos.app.goo.gl/HVquqcTbcou9XFr97 https://photos.app.goo.gl/SMN57QU1XRG9vvcdA |
So on your tire pressures, are those your starting pressures??? If so they seem pretty high. For a 200 tw tire I would look for my tire pressures to be no higher than that hot. I run those those pressures on the street for daily driving.
I would recommend lowering your cold pressures by 4 psi and make adjustments by two degrees up or down based on your target hot pressure. Just a suggestion. Sent from my SM-G965U using Tapatalk |

The tire you are running has very soft side walls so it can impact cornering. So get a more track oriented tire will benefit you at this point. Tire pressures determine performance and lap times greatly. You want to be lapping at the tires optimum temperature and for most street oriented tires that is going to be around 36 psi give or take a couple of psi. Our cars are fairly heavy and you can see as much as 10 psi gain depending on the track temperature and how hard you work your tires. You should check your tire pressures at the beginning of each session and take notes. The first session tire pressures is the most critical because every change is based on that. Did you take the tire pressures after each session and what were they? If they were above 40 psi they are very high. You stated that your tires were getting squirrely after a few laps and that is probably why. Often you hear drivers state their tires were greasey when they are over heated. Lastly you like the feedback from the Garmin when it says nice job but are nervous when she tells you to push harder...well you need to push harder LOL. You got to grow a pair if you want to go fast and you are at that place where you got to trust you tires as there is more grip there than you realize. Get a instructor to ride with you and I mean someone that is a successful racer or time attacker. They will inspire you to push beyond your comfort zone. I can hear my favorite instructor in my head when I need to push beyond my comfort zone..."don't you lift, don't you fcking lift!" Sent from my SM-G965U using Tapatalk |

Yes when she (garmin) tells me to push harder into a different comfort zone for me. Trust the tires, yea, that says it all... The instructor/coach part, did inquire into one for the next track event, not sure what will happen. Do appreciate all of this, working on it.... Thanks again.... :tiphat: |
Right on! Just keep going. Getting comfortable is your enemy. Getting you tire temperatures right can mean a second or more.

Well track season about over for me, I have two more events on my list
-- Z1 nationals at Road Atlanta 10/8 -- SCCA Track Night at AMP 10/20 Starting my list of things to do this winter --- 1) time for new tires, now have to decided whether 18 or 19, I have wheels for both, but both sets are stagger 2) Nismo V2 bumper, thinking on this too.... 3) finally the YAW Switch mod (yea, I known) 4) Figuring a way to install the Garmin Catalyst in center console. 5) paint correction, it is 10 years old, build date was August 2011... I think that is plenty for the winter.... putting things down, so I can start thinking and trying to figure what to do.... |
Z1 Nationals - Road Atlanta Notes:
-- Day was made up of five 20 minute sessions, there were five groups instructors/Advance (red)/Intermediate(Blue)/Novice 2 (yellow)/Novice 1(green). -- morning session was wet, no rain, track was drying through out the morning. I was turning times around a between 2:00:00 and 2:05:00. just taking it easy. Not trying to do anything stupid. -- afternoon sessions the track dried out more and more, so by the last two sessions it was dry. So it got to be fun. Best time was a 1:56.659. Things I learned -- Tire pressure, started working on having my tire pressure when I came back in at 35 front / 33 rear. The car actually felt better all around. -- Time, oh there is more time to lose, but, self preservation was in play. I have to work on my braking, a little bit at a time. Notes: -- At one point a session I was in was blacked flag, found out that Road Atlanta was upset with the rise in incidents occurring. So they basically had all the groups take a time out. -- car performed extremely well, glad to see that it can handle a 5 sessions. -- Tires, its time, I actually corded my right front tire on the inside. When I was doing my post track inspection, I found it. Checked the rears, even wear, but they are done. -- going from 10a/10b to 11 and the hill, I felt better about it. (still respected it), but I think the sims, helped me with the understanding of that turn. -- Turn 1, apex was a bit early, found that out at the end of the day. :driving: |
Today marks the 10th Anniversary of spending all day at the dealership, and finally agreeing to purchase my 2012 Black Cherry Sports Z. In looking back, just wanted it so bad, and I finally got it. I was the only one to take a test drive, because, it was still in shipping wrap. So all the miles are mine.
Its been fun, making it my own personally Z, with the mods I did, pure enjoyment in driving and tracking it. I also think this is the longest car that I have ever kept, and it is not going anyplace. Still enjoy it today as much as back then :happydance::driving::tiphat: |
My last event at Atlanta Motorsport Park, was my best. Not time was, but driving was. A little history, at my last track day I had cored a tire and the rear tires are now dead. So I have a set of 18's stagger I was using as winter tires. I put them on and said I would take it easy. :icon17:
So I worked on the tire pressures and hit the right combination of pressure, Worked on understanding the grip on the first run, and looking ahead. In last session I turned a 1.44.34, which was only 6 tenths slower then on summer. But that lap was the best I have done, seem to hit all the marks and in the end it felt so good. That's why I have many thanks for many people, from my son getting me into sims, my sims coach and all the folks on the forum that take the time to provide there insight and advice. THANKS Here is the lap: AMP Best Lap |
from my list of things to do this winter ---
1) time for new tires, now have to decided whether 18 or 19, I have wheels for both, but both sets are stagger Decide to square with ENKEI RACING RPF1 - finish Black - offset +15mm Now tires still up ine the air 285/35/18 or 275/40/18 Depends on what I can get I really would like to go AZENIS RT660 TIRE, have them on my Miata and really like them.. Then other might be the Nitto NT05s So looking and thinking. :tiphat: But if anyone else has any suggests, always willing to learn... Also anyone have any recommendation to buy wheel/tire combinations |
Good thread.
It has been a pleasure to read it. So how many miles has the car now ? :) For your tires, if you still do a lot of tracks, I would recommend the Nankang AR1. They are really great and we see a lot of people doing trackdays with them. The only down side would be that they wear quite quickly. I do not know compared to the two you mentioned. Cup 2 from Michelin but they are quit expensive as well. |

Miles on car 66000/106000KM... I have looked into the Nankang AR1 and concern it they do wear quickly, the car is driven to track events. The Falken AZENIS RT660, is a 200 treadwear, which I have heard and experience good things about here.... :tiphat: |
Belated Happy New Year...
Kind a tune out for a bit. But I have been doing things. 1) Mid-Ohio lapping day certificate, now have to wait for the schedule and see if I can do Mid-Ohio and Nelson Ledges in a week to 2 week period. 2) sign-up for ZCON 2022, to do Barber Motorsports, figure I need to go to at least one ZCON 3) Order tires and wheels, went with ENKEI RPF1 18x10.5 and Falken RT660 275/35/18 square setup 4) Tracking this year, really working on a schedule. My preference is to do one day events or SCCA Track nights. 5) Look for a coach/instructor I can hire and work with, this might be interesting depending on what type events I am going to do.. 6) Track prep, usually,, new brakes / flushed brake-clutch. Flush cooling and get rid of anti-freeze and maybe also flush transmission. Clear Air filters. normal stuff before a busy season. 7) AMP (atlanta motorsport park) has something called Taste of AMP, which a 3 hour class/orientation. Might be fun to see how close or not I am to driving the track, since its the track I visit the most. Think that is where I am at right now for now. :driving::tiphat: |
Track prep has begun...
cleaned the air filters like I do every year, so much fun, but its done. First event going to be at AMP on 4/13. I have also figured out how to do SCCA Track night at Nelson Ledges in June. Excited about that, because it is where I learned how to drive my Formula Ford back in the day at a SCCA driving school. Hopefully will finish the schedule by the end of the week :driving: |
Sounds like a sweet set of plans in motion!

Last Wednesday (4/13) I did my first track event of the year, it was at SCCA Track Night at Atlanta Motorsport Park.
Just commenting on how my evening went. It was the first time of running a square setup (alken AZENIS RT660 - 275/35 18 rims ENKEI RPF1 18X10.5 +15 ). SCCA Track night is setup for 3 20 minutes sessions. What made this night so interesting, they asked me to move up to advance. I said ok. Was a little axnoius. First session - start with tire pressure on the High side - Cold front 34 cold rear 32. Just a way to get an idea on how the fires were going to perform. It was just fun getting back on the track and getting back into the groove. Came in and the tire pressure hot was 4 pounds too much all around. So for the next session I dropped the front to 32 and the rear to 30. I got out a little late on the 2nd session and immediately had to let a porsche boxster and C5 vette by. These two were running pretty close together. So once I found my pace, I caught up to them. And for a bit it was a 3 car train. But after a couple of laps the Vette pointed me by and the next lap the porsche did too. And to my surprise I pulled away on them. Felt good, car felt good and turned my quickest time 1.39.64. But was not the most consistent when it came to lap times. Checked tire pressures and they were about right on, Except the front left, it was a couple of pounds about 39. So next session I did the same starting pressures, but dropped the front left down to 31. The last session I wanted to be more consistent with my times Things went well. Low of 1.39.94 and high of 141.47. That felt real good. It might have been help with the fact the I was following a s2000 and keeping pace with it. Close enough to follow, but not close enough to go around. Thou I did run into two new items I need to learn about. 1) Turn 10, I could feel the left front rolling on itself. Even thou the left front pressure was a bit higher. So next time leave the pressure a bit higher 2) Next, is I was hitting the rev limit coming out 16 to the start finish line. Hmm, I said, must now be carring more speed out of 16. So it was a fun and interesting evening Attachment 149833 Attachment 149834 |

Well where to begin, On 5/5/2022, I went and did track night at Road Atlanta, a track that does demand a lot more respect. Concrete walls, the SCCA Track Night even made that a strong statement before the start. Yea, its very interesting...
I was in advance and must say, the first session was spent a lot of time looking in my mirrors, oh my, the number of fast cars and letting them by. So the whole point was just hitting my marks, etc. and getting comfortable. Best time was a 1.56.26 it really was on my only clean lap. The second session was my best the times dropped each lap and I had found a space where I was far enough not catching anyone or anyone catching me. Worked hard on hitting my spots. The other thing was I have developed more confidence in my braking, and was breaking later and also carrying more speed. Actually this session was validating working on sims, and transferring to the track. It was pretty close. I noticed after the last session that here, I was having a lot more tire / fender rub on the front tires. I did notice it at Atlanta Motorsport Park, but it seems more severe. Which had an impact on the third session, was concern and backed down a bit and had to watch my mirrors more. Pointed a car by, messed up corner 5, went off a bit and said I am done. Later in the week, I reviewed my fast lap Video There were 4 sections I hit 100 mph or over, and down the long back straight hit 126. Then took 10a at 60 mph. The only reason I mentioned this, is that I am even amazed at how I am driving and just looking where I need to brake and turn, etc. No thinking about how fast I am going, it just seems normal. I reviewed the video with my SIM coach, and down to just fine points on the corners. I do think there is a bit more speed, but how much is really left I do not know, but then there is self-preservation that sets in. Also next time for Road Atlanta going to sign up for HPDE for a day and I will have an in car coach. Really ready to have some other input. This will be interesting.

Are you still on stock brakes? Essex is making a 370z and new Z AP Racing Radical brake kit. They just measured my car and I picked it back up Wednesday. They will be installing them in 8 weeks or so. Finally, a BBK for my car. I have been needing them for a long time. They are not cheap but your consumables should go way down. Just throwing it out there since you have turned into a track rat.

By the way, Essex will offer front and rear. They did tell me some of the specs, I just forgot. I don't really care about the size of the rotors, etc. The bastards just have to work properly. I put my trust in a company that does this kind of stuff for race teams and has done it for years.

None Tracking notes from SCCA Track Night .
A couple of items from the night, John Morton and the famous 240Z was there. Some one had rented the track for an hour before SCCA track night and he was out there running. It was simply amazing to watch it run. Afterwards in talking to one of the individuals, its not the originally car, since that was total. But the owner of the car has all the parts that were left and have built the replicate identical. Attachment 150249 Lots of comments on the Z. The gal at McD's pickup window, on the way home I was passing a BMW, not a new one and older one, nice gold color. We look at each other the same time and gave each other the thumbs up. A neighbor made comments and we talked. Still amazed as to the number of comments, I still get today on the car. :happydance: |
Danegrey - I have thoroughly enjoyed reading your Journal and life experience with your 370. I live just down the road from you in Lenoir City and have had my 2014 Touring Sport since January. I would like to have some mods done to my car and I wanted to ask if you would share the shop you used for your performance mods. Thanks in advance for anything you can share.
