I've got aftermarket suspension, intake, exhaust, and radiator. So, what SCCA class does that put me? Anyone?

 

You'll have to be more detailed than that on your suspension mods....

 

GAB super R 8-way adjustables with lowering springs...eibach i think.

 

unfortunatly your somewhere between ITS and Showroom Stock. Showroom stock means stock. ITS is a bit more than what ya got,, suspension is pretty much unlimited but engine has to be essentially stockinside. Grab a GCR for your sanctioning body and read through that and it will tell you the mods you can do. Good luck in your racing!!!!!!!!!

 

thanks!

 

Autocross I presume? In which case there's no Showroom Stock or ITS classes, besides, SS is for cars less than 5 years old, and ITS is for FC's.

For the FD, you'd be in SM2 I think, maybe ASP, it's dependant on what you've done, look up the rules and decide for yourself. In either case you'll probably be seriously outgunned by cars prepped to the limit of the rules (depending on who shows up).

 

If you're talking autocross, the car is ASP because of the springs and intake. If you had stock springs and stock airbox (K&N filter is ok) you could be in SS. Not sure about the radiator.

Obviously you should take time to read the rulebook though and verify everything yourself.

For autox, non-OE radiator put you out of both SS and ASP

 

Wow, that's a little surprising. But good to know.

You need Acrobat:

Is that ALL you have? They consider things like steering wheels, seats, battery placement, rubber etc...

 

Yes, it sucks. There is currently people requesting to allow after-market radiators in SP but probably not for 2007. That means you get to lose in BP. Or, you can just run in ASP like a few people I know.. ..a local region can be as flexible as they want to be and let you run ASP... until you run into folks at a divisional or national event; then you'll get protested out of ASP.

 

Under what rule does his car not conform to ASP? I'm not seeing anything that mentions aftermarket radiators.

 

If it doesn't say you can then can't.

 

Beginning of SP, ~2nd paragraph:

"A vehicle may compete in Street Prepared Category if the
preparation of the vehicle has not exceeded the allowable
modifications of Stock Category, except as specified below."

As C. said, the golden rule in Solo is

If it doesn't say you can then you can't.

 

BP, why not SM2?? Am I missing something?? There is not going to be any competition in BP due to lack of competitors.

 

Yes, you are, the golden rule: If it doesn't say you can then you can't. Do you see anything in the SM description that says you can have a non-stock radiator? (I don't). Even if it did how would you compete against the 3-rotors? Good luck!

 

Uh-oh, I think I've been running aftermarket tire stem caps all this time.



The interesting and odd thing is that aftermarket radiators would have very little effect in Autocrossing. The runs are too short.

Radiators are considered part of the powertrain in SM, so are unrestricted. Use whatever you want.

That's because you don't think like a Solo competitor :-)

What advantage can changing a radiator have OTHER than cooling?
It it's lighter, then you save weight. If it changes airflow, then you improve cooling or maybe charge intake, etc.

In other words, people are concerned that SP cars will run with smaller radiators (not larger) just like they mostly run with smaller and lighter batteries in some classes.

p.s. on the stem-caps, these are of course covered under "Stock":

"Accessories, gauges, indicators, lights and other appearance,
comfort and convenience modifications which have no effect on
performance and/or handling and do not materially reduce the
weight of the car are permitted."

 

You mean "Drivetrain and related components (induction, ignition, fuel systems, etc.) are unrestricted except for the following limitations ..." my mistake, I'm not familar with SM2.

That is the same rule that has allowed folks to build 3-rotor and big turbo cars for SM2, which is somehow easier to compete against than BP? :-)

 

Thats exactly what I was thinking with SM2. You can change the engine, turbo charge a non-turbo car, but you can't change the radiator?? That wouldn't make any sense at all.

 

Compliance to National rules is not mandatory at local level. Most likely, they will let you run in ASP, despite the radiator - usually tolerated. You may run in any higher class of course, including BP or SM2, but then will compete against car with significantly more extensive mods.
