SM class AutoX setup?
Hi All,
I'm running in a class locally called B Modified - basically open mods, 2.0l and above class. The turbo on our Evos bumps us over the 2.0l mark due to rules they have to allow for FI engined cars. I think this is most similar to the SCCA SM class so wondering how I can improve my setup in order to compete better.
At the moment I'm happy wiht my power mods - basically running the HKS cams, fuel pump, 02 housing and 3 inch full exhaust including downpipe. I have an RS so the boost hits very quick and hard, no complaints there.
Suspension wise, I've got KW V3 coilovers, pretty much all the Whiteline bits (steering precision, roll centre kit, bump steer kit etc.) and the whiteline rear sway.
The cars I'm up against, however, are fully stripped out Evos for the most part, running stroker kits, bigger turbos etc and, most importntly I think, full slick tires vs. the semislicks that I run.
What I'd like to know is what the widest tires are that we can run under the stock bodywork, with a little fender rolling etc. allowed. I'm running the RE55s in 18/35/235 width at the moment and think I could benefit alot from maxing out my tires and grip.
So how wide can we go and what offsets, etc? Also open to other suggestions as far as alignment etc. - I currently run -2.5 camber at the front, -1.3 at the rear and 0.05 degrees of toe out all around and I know I could go a little more aggressive in that department if I get the KW camber plates.
Once having sorted the tires out, I'm considering stripping out the interior (lightnes is free after all) and perhaps taking off the rear wing since it doesn't really do much at AutoX speeds anyways.
Feedback/suggestions appreciated! I'm up against a very serious class of cars here and want to raise my game!
