what class for autocross?

[CamaroAJ]

get to take my camaro out for it first autocross this sunday and i don't know what class to pre-register for, i was told XP but not sure. like most people here i have the full DSE set-up front and rear, i also have a LS1/T56 so i know both of those will factor in what class i run. anything else that you'd need to know to help me out?

Just email or call someone from the club. As soon as you run well someone will whine to have you bumped to a faster class.

[vanzuuk1]

And good luck and have a good time

I would not doubt if they try and just throw you in SM. I'm not to great with the classes but I'd imagine that a motor swap would automaticly bump you into SM.

Maby Marry Pozzi will chime in hear. But that probly wont be till after they get back from SEMA.

Oh and when you go out get some pictures to post up so everyone can see.

[CamaroAJ]

well they said sign up for XP and we'll see sunday what class it really fits into. so i guess i'll find out sunday....i'm stoked, not just soe tweeking on the ol ride to make sure all is well and i'll be good to go.

Noooo SM is Street Mod. I think it the highest of the street class.

Unless you're really lightweight, the firewall has been modified to permit setting the engine back, the wheelbase has been tinkered with a bit too much, IRS instead of a stick axle, or some picky thing like removal of the rain gutters, I'd think first in terms of C-Prepared. 3000# is your basic minimum weight with that LS1 in CP, 2350-ish in XP.

Street Mod is wider open than Prepared as far as engine mods go, but far more restrictive chassis-wise. In SM you can't relocate the chassis side suspension pickup points or add non-standard lateral chassis members other than strut/shock tower and lower suspension tie bars, as a couple of examples that come to mind.

I agree.

i think SM has a displacement limit (EVO was national champ this year). you might be in SM2 (3 rotor turbo was this years champ).

[Norm Peterson]

No displacement limit any more (2007 rules). You go to SM2 if you're lighter than 1800 lbs + 200 lbs/liter, or about 2940 for a stock displacement LS1. You do not have to weigh more than 3100 lb maximum in SM regardless of displacement.

i looked on the scca club site for my area and thats what i found. then again there site is so hard to find anything i wouldn't doubt i'm wrong.

i'll try and get into the CP class, they said they'll figure out what class my car will be in on sunday. maybe they won't be smart enough with the old cars to realize all the stuff thats different on it, alot of the cars that race around here are imports with a few newer stangs and vettes.

Remember just have fun.

roger that.

SM is Spec Miata for Road racing.

SM for Autocross is Street Mod.

Toss up between SM and XP - Terry Fair had an BMW E36 M3 with an LS1 (bolts right in) www.vorshlag.com at this years SCCA Solo2 Nationals

I would say XP is new new evolution of SM

[deak350]

I have a 67 Camaro and because it has a supercharger, larger brakes, relocated A-arms and 17" wheels I have to run in an Unlimited Class. It makes for tough competition (Ferrari Modena Factory Racecar, Porsche GT2's, Tube chassis RX7's) but its still fun.

I'm no expert AJ but depending on the mods and tires Camaros qualify for several classes:

FS (F Stock) if bone stock (yeah right)

ESP (E Street Prepared) (allows lots of mods, but must run original motor and no subframe connectors)

SM (Street Modified) most anything goes as long as the engine manufacturer matches the body manufacturer

STU (Street Touring Ultra) allows pretty much anything but you must run street tires and widest tire is a 275

CP (C Prepared) nearly evertthing goes as long as it's still a camaro.

of these, with your mods, I think you are looking at SM, STU (if running street tires 275 or less), or CP. STU is least competitive if you qualify, SM and CP are pretty much a wash in terms of PAX. SM and STU will be replete with imports and CP will be where most of the domestic cars reside. So to be most competitive look at STU, but to race heads up with the other guys running domestics you should run in CP.

You'll likely never be nationally competitive in CP with a pro touring car with full interior and all of the other comforts but it's a nice class to enjoy the company and competitiveness with your fellow domestic guys and you may enjoy some level of success locally.

That's how i understand it anyway. Again, i'm no expert, if the experts know better, please correct me.

CSP and you're in a tough class to compete!

im in the same class without the extensive mods to drivetrain and suspension: zz4/TKO w/ lowering springs and tubed "A" arms.
