Well I'll take your word for it because I don't even know enough about wheels and suspension yet to totally understand what you just said. Care to elaborate on what you just said? :tiphat:.

BTW been watching your videos to learn buttonwillow, thanks for making those. I will be there Saturday with GF if you are there and see my car come say hi!

What i was trying to say is, since your ride height is stock, its higher for example to mine, so the wheel/tire/suspension would have a longer distance to travel before coming in contact to body work then on my car which is lower(but by no mean "low"). Also, since the length of the shock body is longer then aftermarket coilover shock bodies, under compression load, you'll bottom out( hit bump stop) with your wheel/tire further from the body work then if you had a aftermarket coilover with shorter shock bodies. This is my theory as to why you are not rubbing with 18x10.5 et15 285/35/18 up front.

Any questions you have from watching the vids? have you been there before?
i wont be there saturday, only Sunday for the time attack, ill be driving the Black JDM Civic Type R i drove at Willow springs

Chris you probably already ordered them but Costco in Waipio has pretty good deals on RE11s if you like them and they work for your size.

My only concern with Hoosiers is that you probably need more seat time with street tires before you can take full advantage of a set of race slicks. Most of those guys auto-x with us in Hawaii region have been doing it for decades. Heck, I want to say there are at least 5-8 National Championship drivers in the field. My point is they make it look easy on slicks. Learning on street tires for 1-2 season will work out any bad habits and make you much faster (1-2 seconds) on slicks.

I have not done Button Willow yet so first time Saturday, we have the Nissan competition that day. Martin's and my car are parked next to each other up at corner 3 right now lol, his rear suspension was a mess when I dropped mine off last Saturday but I am sure Steve got it figured out this week.

I have contemplated staying on Sunday for a few sessions if I can keep the GF entertained long enough. It's a long drive for just one day. If I stay there I'll look for you, otherwise have fun and be safe.

No questions probably until I get a feel for the track but definitely have watched your video about 20 times already to try to memorize the turns!

So after my further explanation, do you get what i was saying?

hope my vids help, i look forward to getting back out to buttonwillow with the Z on better tires then that vid

GSS138 07-19-2013 05:02 PM

Yeah, I get what you are saying, but isn't the post market setup also going to be tougher to bottom out with just because it is a stiffer system that is harder to compress?

that is true, but unless you get a coilover with like 25k springs, the suspension is still going to articulate through is motion significantly

Jay, I work at the Kapolei Costco Tire Center :tup: My only problem with the RE-11's is the max rear width they offered was a 275 and I just wanted a little more. The BFG Rivals are actually a street tire but they are VERY close to a R-Compound. I won't be going with slicks for quite some time. Avery tested between the Rivals and Re-11's on Sunday in his 2 Miatas and he actually consistently ran a full second faster on the Rivals then the RE-11's. Obviously he is one of those super skilled vets that you are talking about so I don't expect as large of an increase. I actually feel pretty good as my 1st 5 events was on All season tires lol. Just gonna step it up to something stickier and see where it takes me :tup:

cv129 07-20-2013 01:25 PM

^ was it RE11's or RE11A's that were used against the Rivals?

chrischhorn 07-20-2013 04:09 PM

Sorry RE-11a's. Still not use the "a's" part lol

Cool makes sense. I don't think I will be buying a setup till next season so I am trying to learn more about them.

Did Button Willow today-was very hot and slick, bad traction. Didn't push too hard since it was my first time and am still a beginner level driver, but was able to put in a 2:25-which isn't great but was middle of the beginners group and I consistently got faster all day.

Except for the main straight aways I stayed around 90% throttle most of the time since I don't totally have everything memorized yet. I think once I am a bit more comfortable I should have no problem dropping into the 2:15-2:20 range once I am not afraid to open up on "Riverside" and the "Dragstrip".

"Club corner" kinda spooks me and I know I can take it faster, but it's a mental game on that one. Bus stop no problem except for one time I sort of forgot that it existed and went straight off lol.

Couldn't stay because I have to work out of town monday so figured it best to come back tonight. Good luck out there tomorrow Clint-stay hydrated!

Not to beat a dead horse, but they do clear. I run 18x9.5 +15 front and 18x10.5 +15 rears with no clearance issues. 265/40's up front, 285/35 in the rear. Dropped on coilovers.

Not going to a formal classroom/racing class or school, but we do 1 hour of driver education before every event. Also, I get all day instruction every time I go. I probably will stick with all day instruction for a while until I get a lot more experience-like probably well into next season.
