So what SCCA class do you guys run? What mods do your cars have?
I'll likely be setting up the car with subframe connectors and Koni's and new struts.
I've been out of the auotox thing for quite a while...back in '98 going to Eibach's and Koni adjustables moved me from C Stock to D street Prepared or something like that LOL...I think now it would be in G Stock (maybe not...the brakes...) then moved to Street Prepared E? Street Prepared was just starting back when I got out of it all.
In autocross there are basically 5 SCCA classes the SHO can run in.
Stock SHO runs in G stock with the Mini's. You can add R compounds and a roll cage, but no SFC's or SFB's and no Quaife.
SFC's and/or aluminum SFB's will land you in Street Modified where you get to play with the tricked out BMW's and Hondas with their superchargers/turbos, engine transplants, coilovers, carbon fiber this-and-that, and R-compounds. You have to leave the interior in, however. Good luck running in this class.
Or you can take your stock SHO, add coilovers/Koni's or Koni's/Tokico's with Eibachs/Intrax/Moogs/ + non-metal subframe bushings (i.e. delrin SFB's, or possibly even Gen 3 subframe bushings), racing seats, a Quaife, big brakes, 8" wide rims with 245 rubbers, and a Y-pipe
but don't add subframe connectors, and you'd be legal for STX which is a street tire class, but the SHO will be much more competitive here than in SM.
Intermediate between STX and SM is one of the Street Prepared classes (ESP or DSP I think). You can add more engine mods beyond the Y-pipe, and run R-compounds on wide rims, but you
cannot use SFC's or aluminum SFB's.
Another option would be to strip the **** out of it, stick in a 3.2L, coilovers, Quaife, SFC's, SFB's, etc., etc., etc.
except for forced induction and run in C Prepared with the big block V8 sedans (Mustangs, Camaros, Firebirds, etc.) where a highly modified SHO with a better-than-average-driver could potentially be competitive. There is a minimum weight restriction in CP. 2550 lbs. for V6's, and 3000 lbs. for V8's (IIRC). By "competitive", I mean finishing in the top one-third of the class that by definition gets you a trophy.
The point is, once you add SFC's or aluminum SFB's to the SHO you wind up being in classes (SM or CP) where you will likely be non-competitive unless your SHO is heavily modified and you are a better-than-most autocrosser. It's probably better to forego the SFC's/aluminum SFB's in the beginning and run in G stock, STX, or Street Prepared while you collect seat time.
