1. Did you change brake fluid to fluid that has a high temp rating?

2. Are they track rated pads?

Nice :tup:

Local course or is it online? Is there a website?

Online course. But it comes with access to their member's only forum where you can ask questions specific to your application. The guys working for this company are motorsport engineers/professionals that do this for a living. So who better to ask than these guys?!

I typically stay away from stuff like this because I usually know most of what they are preaching but what sold me was their free live 2 hour course to give you a "taste" of what they have to offer. Immediately, I knew this was worth the money. I think I only paid $90 for their package for black friday.

Best books I have found, even though they are old the fundamentals and physics never change.

I have both of those books. :tup:

stock sport pads, fluid is srf

Talk about opposite ends of the spectrum. Change out those pads bro. They will overheat and fade long before the fluid. You're just wasting that expensive SRF by using it with stock pads :twocents:

gotcha! I just replaced lines so thats why i had that fluid in there cause i needed to fill it anyway, and has a higher boiling point than rbf 660.

also, should I replace front and rear, or just front?

any pads you recommend?

Replace both front and rear. I started out with EBC Yellowstuff pads. As I got faster. I switched to the Carbotech pads.

sweet...looking at corbotech from z1, theres so many options. which pad type did you go with?

okay so i ordered xp12's for the front and xp10's for the rear

thank you gentlemen for all of the help!!!!

That could be a bit much. I'm using the 10F/8R combo.

guys from z1 recommended, told me to be mindful while warming up and ill go through my rotors a little faster but im okay with all that

they said some people daily this combo

Be prepared for the squeak when cold.

I agree with Rusty I ran xp10 front and 8 in the back. They were plenty and they squeal like mad when they are cold. You may experience either a hard bite or no bite at all when they a cold. They also dust really bad if that is a thing for you!

RaceCar..... I love it when they squeal, just annoys the hell out of everyone around me. I just laugh.

lol the squeak never gets old for me

yes i have to be mindful to warm them up, why would i get a hard bite? i though i would have to worry aboout no bite til up to temp

eh the dust doesnt bother me lol

All I am saying is that until the brakes are up to temperature they are unpredictable as I have experienced them to not bite, ice mode or grab and stop on a dime. Just providing food for thought.

I most definitely appreciate you, i just didnt understand the hard bite. Gotta be super mindful, thank you for that

i already have to take it easy for the first 10 min anyways cause of the nankang ar-1 i currently have

I run XP10/XP8. It always surprises me when I think they're too cold to work and you end up slamming the passenger into the dash. Also the squeal. I don't know how some of you deal with it but man is it high pitched lol.

Anyone measure bump & droop when installing coilovers? Roll Center?

Here are some pics of my bump(full compression, no springs) and droop (full decompression).

Rear full droop:

Rear full bump:

Rear Ride height:

Front full droop:

Front full bump:

Front Ride height:
https://i.ibb.co/JRFmzCZ/IMG-8588.jpg


Measurements: (from the top of the center cap to the center-most part of the fender)
Rear:

Fully Compressed (no spring): 317.5 mm

Full droop: 444.5 mm

Ride height (car on ground with spring): 352.425mm



Front:

Fully Compressed (no spring): 311.15 mm

Full Droop: 444.5 mm

Ride Height: 342.9mm

I may raise the front a bit, looks like I'll need a swift spring to properly preload the fronts, If I go any higher, the springs become loose. Only way to tell is to do a corner balance which will hopefully happen after I get my half-cage done.

When you did this. Did you watch to see how much the camber changes during full movement?

Would be very cool to know, at least as a reference. Would also love to know the changes in toe.

One can only dream. Watching Forza replay with live camber values overlay is fun, but not sure how realistic it is lol.

Unfortunately no, I haven’t aligned the car yet after installing my
SPL FUCA’s. So alignment is all outta whack. I do need to buy some mobile alignment tools to measure this kinda stuff.

Just moving the tire up and down, and eyeballing it.

Make sure you change your coolant heater hose junctions kids. Mine popped while I was gridding for the first session of the day.

this the right part?

I just went with one of these things.

oh nice! is the z1 piece the same thing you bought with just a bleeder port?

i have 8000 miles on the odo(only 2 track days), you think i should change it before my next track day?

You might not now, but it is a part that's known to degrade as you get heat cycles through it. My car has 163,000 miles on it, with maybe 15 track days, and it finally went.

ah okay....definitely gonna fo it soon

Thank you!

Bump.


Curious what competitions everyone competes in.

I currently compete in:
-gridlife Street class
-Scca TTU

If I ever get my Z back I will run in:

NASA TT2
Nissan Challenge Unlimited

May jump in on some others depending on cost. I would love to go t Super Lap at COTA just to say I have done it and check them both off my bucket list.

I finally did my first track event in my z. I actually did a track day in my Civic maybe 10 years ago before I ever started autocrossing but still prefer autocross for competition. Might do a couple track days during the off season just for fun.

I'm just happy nothing broke but I do need better pads. Currently on hawk hps but will get a set of carbotechs before I go back.

Also, regarding toe changes through the suspension sweep, it really shouldn't. The way the suspension is designed that would be a highly undesirable feature and would lead to bump steer if the car encountered a bump on one side or the other. From doing my own chassis setup for the last few seasons I've found that you can change the height pretty much as much as you like and that will only affect camber. However, once you correct or adjust camber it will throw off toe.

Did my first track day in the Z. Fun and eventful day. I should have done more research before going out there. Had no idea of the fuel starvation issues these cars have. When I noticed the sluggish with 3/4 tank I was in full denial. Oil temps got to about 250-260 on a 70-73deg day. Unfortunately, it was the first time I had to get the towed off track.

Oil cooler already on order? Lol

Yup, ordered oil cooler and fuel starvation kit from Z1. :facepalm:
