how competitive are FCs in autocross within their stock classes? it doesnt really matter to me all that much but i would like to be competitive if i get one. which is the best for autocross in your opinion?


also, why is the T2 in Bstock where all the other models are in Estock? that seems like an awfully large gap being that Bstock has cars like 300zx tt, pre 95 porshce 911, s2000, e36 m3, and Estock contains like, the miata 1.6, 280zx, and porsche 924 theres only like a 20 hp difference right? does the T2 have an advantage over the N/A models other than power?

 

Ahh the never-ending question I always ask my self each season. It just comes down to the rules and specs on true 2 seater sports cars is tough. If you had a 2 door sports sedan or sport compact that fit 4 people life is just a little bit easier.

If I were you, I would do what I did not do. That was to get the car up and running smoothly in the stock class to get a feel for the car, before jumping into the pit with the Lyons, Tigers, and Bears “oh my”. Pretty much once you have done any modifications it puts our cars in the Street Prepared class. Once you’re in that class your up against some mean vehicles. The FC’s are competitive but it takes skill and some cash and one pissed off wife cause you out every weekend racing .

Hmm what would mine be under?

88 GTU converted to S4/5 TII.
S4 internals and S5 manifolds and turbo.

Racing beat DP to PS to Corksport single.
Apex BOV
Walbro
TID
NA LSD rearend

but stock tire size!hehe

Not exactly stock since it's a different engine.
I think I'll get owned by the others.

 

You are definitely in Street Prepared and could be bordering on Street Modified. This would be a question for the SCCA tech when and if you go to your next event. To be on the safe side I would say you will be in Street Modified should be ASM.

The motor swap would put you in SM2. The real T2's with your mods run in ASP. You might be able to talk them into letting you run in ASP. Either way you're in trouble.

dunno the exact rules, but odds are very solid exhaust and fuel pump will put you in street prep.

 

A good site to help you find out what class you belong to is here ---> http://moutons.org/sccasolo/

 

man that stuff is confusing!

 

I'm in the C-Prep class....:O

My mods don't even seem like alot.

 

Off the top of my head, I think I'm in C-prep, but Im affraid I'm actually in street mod. Looking through those rules is like trying to understand a legal document. I noticed that an FCD, boost controller or wastegate porting is NOT allowed under street prep. That'll eliminate most turbo owners. Also, why the hell is the T-II in a-prep? Thats the same class as the 360 Modena, corvette, most lotus cars, and friggin TVR's. Thats just wrong. A Cerbera or Griffith 500 could prob kick the *** of a Ferrari in auto-x, let alone a poor T-II

If your engine is indead street ported you out of any prepared class. Welcome to Street Mod.

I noticed you have coil overs? To get the best performance out of those you need to have your car corner weighed. If you do not do this to your car.....and you have coil overs.....well...the money could have been spent better. The only reason I mention it is becaues you want to race with your car.

Lets put it like this. Your car is not competive for what you have done to it. The porting has put your in a level of competition that your car is not competitve. It might be in a local club. But if you start going to higher levels it won't be. Also, the min weight for SM2 i believe is 2500. But I suppose that is if you are competing at national levels.

If you want to be competitve at solo 2. Your best bet is to start putting money towards driver schools.

Here is a less confusing site of what you can and cannot do in stock vs prepared vs modified classes

http://www.sff.net/people/dburkhead/prepcompare.htm

If you are considereing running in ASP or SM2 it's pretty much a no brainer... the PAX difference is almost non-existant(0.001 difference 0.848 vs 0.849) this season. And you will be more competitive with the mods you can do in SM2

 

I run "csp" a lot of miatas run in this class and it is hard to beat their cornering....but you have them on the acceleration end...buy tires and suspension first then work from there....with a good set of kuhmo slicks you will have a million times more confidence in the car and your times will improve drastically over little bolt on improvements.....

 

I really wouldn't recommend a set of slicks for your first few seasons. You probably wouldn't be able to use them to their full potential and also wear them out prematurely. Also any mods you do to your car will further hide bad habits. Unless you want to be the rookie of the year, having a stock car will force you to overcome bad habits.

 

You can't run "slicks" in street prepared, stock, or SM2 classes anyway, so I wouldn't worry about it. Kuhmo doesn't make slicks. What you're meaning to say is that you should pick up some good tires (Kuhmo V700's is probably what you meant). A set of tires, even for a novice, will shave a couple seconds off the top. They also allow the driver to feel the suspension working instead of having the car slide on hard winter tires under moderate lateral acceleration.

I whole heartedly recommend Falken Azenis. They are about $300 for a set, outstanding in the rain (with full tread), will last an entire season (properly broken in and they will slow down), and they are pretty sticky. Not the fastest tire out there by any means but definitely a great introductory tire. Price to performance is phenomenal.

Ok technical Guy....."slicks" so freakin sorry and yes i am refering to the v700...i wasn't talking hoosiers, most people i race with call a race tire a "slick" so go >Edited for content<

sorry i shouldn't have said most of those things ...the things i wish i hadn't typed are as follows.......technical, sorry, i, refering, wasn't talking, most, people, race, tire...

>edited for content<

 

if your boost or fuel is altered in anyway, you are in a Street Mod class, for FCs it would be "SM2". rules are goofy...hell, i remember a friend of mine being thrown into "SM" cuz he had a BOV on his WRX. that's it!!! so he just took it off then and there and raced as D-Stock.
NA FCs will always be in "ASP" for mods and such. the only way they get thrown into "SM2" is if they have any engine mods like a street port.

oh and yes, you can run race rubber(Hoosiers, etc...) in SM2 and street prepared.

 

Race rubber, yes. But it must be DOT approved so no slicks and I believe even a few of the Hoosier DOT approved tires aren't allowed, though I'm not 100% on that as I don't run them.

 

watch the flaming... your post has been edited

 

Actually N/A rx7's run in CSP
