Street Modified?

Lowend · 01-07-2002, 09:48:00 PM

I have always been awful at classing cars.
What makes the difference between Street Modified and CP?
While my car is quick I'm not willing to cut it up enough to run CP in a competive manner
With NASA its easy, I run Vintage Street Prepared (VSP) but that dosen't exist in SCCA.
Someone help me out, can I get into SM?

I am by no means an expert on the subject, however I plan to run my pos in this class when the new 400 is done. Until then I am running a friends 69 Chevelle in that class.

My rule book is older and doesn't contain SM. I have a lot of friends in SM, and it seems that it is essentially street prepared with additional internal engine mods allowed. Basically it seems that it is for street cars with big engines, that are not cut up. I have a new Rule book on order and I'll tell you more when I get it.

In street mod you can do engine swaps and also change internal engine parts, unlike street prepared. You can run subframe connectors and can modify the brakes, too. Everything else is very similar to street prepared.

what does street prepared entail?
Even though I don't have any SCCA events anywhere near me, I'd like to try sometime...

Lowend · 01-09-2002, 10:46:00 AM

Here are the mods I've done that matter in classing
:

1971 Camaro (duh)
12" brakes stolen from a GM fullsize
aftermarket springs
rear leafs relocated for more anti-squat (not that anyone could tell by looking)
16x10" wheels
De-lum bushings in the a-arms with offset crossshafts
Front and rear VSE swaybars with hiemjoint endlinks

Now I have been holding back on a set of Weld-in Subframe connectors so as not to get tossed into CP. Can I run them in SM? I was under the impression that if you weld on the subframe you are in CP... am I wrong?
I know that engine swaps are ok, I've got a 500HP 383 in the works, are there any engine limits I should know about?

I can never make heads or tails of SCCA classing.

Sorry to break this to ya, but your brake swap already puts you in CP, or street mod.

Lowend · 01-10-2002, 01:52:00 PM

I don't think its fair that I have to run with 2700lbs cars with tube frames and 600+ HP just because I have station wagon brakes.
Now... lets say that my brakes are not particularly obvious and I only plan on competing at a local level (not gonna go to nationals)... what kinda class would I be running?

ovrsteer · 01-10-2002, 02:29:00 PM

If your engine internals are stock, then you could get away with ESP. However, sometimes ESP is faster than CP, it depends on the people competing. If you have engine mods and they are not obvious, and you don't mind cheating, stay in street prepared. Otherwise, I would say that street mod would be a fun class in your car. You can legally swap internal engine components, and do a lot to the suspension while keeping the car streetable.

Lowend · 01-10-2002, 08:44:00 PM

I think I'll give SM a shot.
While my brakes are subtle, my engine will not be.
Lets not call it cheating... lets call it creative interpretation of the rules.
They are after all peroid correct GM brakes

If you think its unfair to bump you into CP for the 12" brakes just look at what the SCCA did to A-sedan. I am a SCCA member and run both solo and club racing events. I like the SCCA but some of the rules I don't like. As far as your SM question, let me look over some of the updates in SportsCar and I'll get back to you in the the next day or so.

patgizz · 01-15-2002, 10:18:00 PM

i emailed the scca classification people for the hell of it cause im gettin ready to join for next season's autocrossing. they said definitely CP - duh - but pushing 200hp less than the big dogs isnt gonna help me on any level but local.

so whats the deal with the 16" rim max - 2 guys in our local club came in 1-2 in CP last season in the local standings and both were running on 17's.

ovrsteer · 01-16-2002, 12:00:00 AM

You can run a maximum diameter of 16" in CP or whatever size wheel the car came with from the factory. So if you have a fourth gen camaro, you can run 17x9.5 wheels, as the SS came with that size.

Hi, FRF. So you run AS? Cool, what part of the country? Have you heard of or done any of this Camaro/Mustang Challenge racing?

I'm not planning on running AS anymore. I am currently in ITA and building an ITE car(2nd gen f-body). We are in SOWdiv in Texas and have heard of the challenge race. I have a friend still running AS but don't know of any plans on running in the challenge.

ovrsteer · 01-16-2002, 11:57:00 PM

ITE in a second gen? Sounds cool! What are you allowed to do in ITE as far as engine and suspension are concearned? We just got a road course/ drag strip in our region and I'm interested in doing more than Solo II. BTW, I'm in SWDiv too. I live in New Orleans and the new track is between Baton Rouge and New Orleans. How expensive is IT racing compared to Solo I. Is there a 13/13 rule in IT?

street mod is a fun class. the rules are very wide open:
1. you can swap in any "production" pushrod motor up to 6liters, and any overhead cam or blower/turbo motor up to 4liters.
2. any suspension part you can bolt on with out drilling any new holes or changing the size or shape of an existing hole is legal.
2b. front sub frame/ k-member must be factory, but any control arm or suspension component that bolts onto it is free.
3. replacement body panels made of any material that bolt on to stock mounting and do not relocate or remove any other stock parts are legal.
wheel and tire size is unlimited and may stick out past wheel well lips as far as you want
4. update/backdate rules from street prepared apply.
5. you can remove the rear seats

other than that stuff the rest ofthe rules are basicall the same as street prepared. it is a fun class where you cna take on imports heads up in a no excuses formet. the only draw back is that it is a big dollar class because of hte wide open rule book.

later
