You could put the 8Ks on the front the 10Ks on the rear and use the Saner Bar.

Your 1/2 degree greater camber in the rear is a pretty typical alignment and the 2 degrees in the front is fairly typical for a multi-use S2000. But, the greater the body roll the greater the camber needed, so addressing the body roll would help.

 

Well Nashville did not go well. Why? Driver! 6 runs and only 1 was clean, well actually 3 were clean but 2 had spins. The increase in front camber fixed the push unless I was going to hard.

I still need to work on the pitch & roll which only springs is going to fix. I won't throw swaybars at it till I get the springs closer to right. 10k front, 8k rear is too light.

 

Springs need to be matched to sway bars. You can't tune one without the other.

 

I don't beleive 8K and 10K springs are too light. The stock CR has 6K and 7K springs. Save your money, put, the 10Ks on the rear, and the Saner Bar on stiff with the 8Ks on the front, that should eliminate the spin issue, and the roll. I may not have read enough here, but, I never really heard anyone complain about pitch in an S2000 even with OEM springs. Yes, you have weight transfer from rear to front and front to rear, but, those are tools that you don't want to eliminate.

 

Pitch isn't the best term likely. Basically through the slaloms the front tire with the majority of the weight transferred to it is really up in the wheel well and the opposite side has a good bit of daylight between the tire/fender. I was calling that pitch but I guess that is roll.

On a seperate note, can someone recommend a clutch upgrade? I think I am getting close to needing one based up the recent smell. :-) I am launching moderately hard with launch control at 4500 right now. I really want something strong and stiff as this is a 99% AutoX car with little street driving.

 

the only thing legal in STR is OEM

 

OEM it is then.

 

At the event today the car continued to be highly loose. After talking with several people I removed one side of the rear swaybar. BINGO! OMG, what a difference. The car was putting power down like crazy. I am wondering if I should re-attach the rear sway and put on a front sway or just leave it. Thoughts?

Also, I am looking for exhaust recommendations. I want a single exit, 70mm, titanium....what I don't want is obnoxious loud or farty. Can I get some recommendations?

 

Ha, same thing here, I will post more about my test and tune later but pretty much the same thing your saying.

Without the rear bar connected though, it did introduce quite a bit of understeer, but at least the car is driveable.

 

I had the T1R EM 70 ti exhaust and LOVED IT. It was really about the best exhaust I've had. I just run a cut stock exhaust now because I have some how regained some sanity on my second STR car build. I don't think it's too loud so keep that in mind.
