SHO classes.

[Mad Celt]

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.

SM. mainly because of the 3.2 swap, quaife, suspension, bigger brakes, SFCs and SFBs, strut tower bars, etc etc etc.

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.

Also note, street prepared does not allow larger brakes, the bmw finally got tossed out of dsp for having e46 330 front brakes


thanks for the list

Gotcha. Unfortunately I already have the aluminum SFB's in the car (came with them from Chris.)

Seat time is really key...been over 8 years!!!

If you're interested in seat time hustle yourself onto the NESHOC website and contact Ed Stebbins. We already have the dates for '08 and early registration is always welcome. You can find all the info there.
NESHOC and the BayState Corvette Club run a basic autox (no car classification rules). Novice, expert(street tires), expert(race tires) is about as advanced as we get for classes. We usually field 40-60 cars divided into two run groups. The course is an 80+ gate event and covers about 1.5 miles. Since we've gone to electronic timing a few years ago everyone usually gets 8 runs on the day (approx. 12 miles) and depending on the time at the end of the day, fun runs.
RJ, just so you know, my '89 is running a K&N panel filter, race tires, SFC, ASFB, Tokicos, Intrax, front/rear STB, relocated battery, AC/heater delete, Plus hood, 19mm/26mm bars, oh yeah, its also gutted.(more to come out)
I just leave my ego at home and run the snot out of it.
I'd like to see you bring your car down, I think you'd have a blast.

Hey! I know Ed from my old NESHOC days!

That's kind of my plan...similar to heading to New England Dragway...run and try to beat my personal bests.

i run in SM due to ... lots of modifications added up. i'm nowhere near being competitive, but i've also only run 3 events and a test & tune EVER, and that was all on crappy all-seasons. so... here's to hoping my driving improves, and my times improve with better tires, lighter wider wheels, and no back seat! (btw, no back seat is ok in SM) i'm also hoping the slightly lower profile tires will help with my gearing being a bit more optimized. i rarely go above 5k rpm in 2nd gear on our smaller, tigher courses that we seem to have all the time.

the guy who is leading our winter series auto-x in SM is a guy in a s/c SVT focus. he's one **** of a driver though. jumped into an old oldsmobile (stock) and beat my average time at his first attempt at our recent test and tune. haha

I thought the sho was the best fit for STX? But I could be wrong. At least that's where I would run it.

 

[sho_bc]

from Fred's breakdown of the classes for the SHO, it sounds like STX would be the best one to run in for most people. i got stuck in SM due to the modifications that were already on the car. over the years, as things needed replacing, i upgraded.

 

[bubba]

How do you do in that class? I want to autox.

 

[sho_bc]

as i wrote above, with my n00b auto-x skillz and sub-average all-season tires, i was doing pretty bad relative to the rest of the SM cars (never came last though! :woohoo: ). i've got better wheels and better tires (and i'm probably going to get a slightly more agressive allignment) that'll hopefully be able to help me gain a couple seconds. that couple of seconds would only put me in the middle of the pack instead of the back of the pack though.

 

[bubba]

My bad man. Should have read alittle more.
