It depends on what class you want to run in and the car you have.

So, depending on the car

(GC8/GDA)

GS/DS (D-Stock) car must remain basiclly stock.

DSP/ESP (STreet prepared) You can run with out CATS but you will be running against mustangs and camaros that are very well prepped. In this class, you can tweak the exhaust, headers, intercooler, but you cannot change the boost controller or BOV.

(STS/STX) Street touring Basically the same as street prepared, but with the added restrictions that you can't change the intercooler along with the boost control or BOV.

SM Street mod. just about anything goes. You need a big budget to spend... I mean race here.

Read the rules on this site. this will give you a good idea of what you can do. When reading the rules, interpret them like this. If the rules don't say you can, then it's probably illegal for that class.

If you have questions feel free to post away!

Come on down to candlestick park saturday, the SCCA will be holding an autox there. Most of the will be running in the morning... j/k

Impala SS AutoX

ESP (or any street prepared class, for that matter) allows deletion of all emissions control devices.

STX requires to pass a tailpipe test. If you tuned it right, you MIGHT be able to do this WITHOUT cats......but it isn't likely

No Autox that I know of (and I know of basically all of them in the Bay Area )coming up anytime remotely soon at Infineon.

why the hell is debadging against the rules for stock and street??

kym

iTrader: (1)

I have no clue. The only reason I can come up with is that 0.25 lb. weight reduction.

Impala SS AutoX

iTrader: (21)

So, has anyone tested the "Any Brake Rotors or Calipers" deal in STX?

If it's legal, I'd probably be looking at bigger brakes (i.e. Stoptech, or even just the Subaru 4-pots) next year. I'd like to go to a few track days, and quite honestly after I've gotten used to my (very NON-stock) Impala SS brakes the ones in the Subaru (even with upgraded pads/lines/fluid) feel pretty crappy in comparison.

Don't wanna knock myself out of STX for them though

Lorry

Although it is against the rules, I'd be really surprised if anyone challenged you over it at a regular SFR event. I think that they are more concerned about removing large pieces of stock trim etc.

Zoeb2s

iTrader: (38)

they specifically say debadging though....they dont mention anything about any exterior trims...

chrisw

iTrader: (1)

The rule was probably written to handle the senario of debagging a late 60's or early 70's car that probably involved removing more than a few pounds of crome.

I was looking at the debadging, too. That would have moved me from ESP to SM, last month. Nobody out here has said anything, though, and I'll be in SM next month, anyway. Interesting.
