I went to an auto x beginner's school and free run event last weekend. I am now officially addicted. I downloaded the SCCA rulebook, and had a few questions.
With my mods( mods are in the sig), which class would I be in?
Super Stock Street Touring correct? If not, why? And where can I get removable numbers? Summit racing has nada.

You can probably just run Superstock or ASP and most people won't care. I think legally you are in SM2.

Larz

What puts me in that class?

The downpipe kicks you out of SS. You can run SM2 or ASP with those mods. I can't remember which is more restrictive, but I think generally you should stick to ASP for now

Larz

****. okay. Thanks. But in that class I'm allowed everything from the previous ones (like high flow cat) and tires with a 140 wear rating?

Imp

Legal for Stock:
EBC Green Pads
Apex'i Autotimer

Not legal for stock, but legal for ASP or SM2 (your choice):
Koyo Radiator
HKS Downpipe
Apex'i Intake
RB Sway Bar Brace
Suspension Solutions Strut Bar
Pettit AST
FC Thermoswitch
RE Torque Brace
Corksport stainless brake lines

In any class the car being discussed above is legal for, it's allowed any DOT tire. (Ie: R-compound all the way through street tires.) So yes, you can run tires with 140 treadwear, but the R-compounds are faster... unless your region has a specific Street Tire class for modified cars like yours. (The 7 isn't legal for any of of the SCCAs Street Tire classes, but regions are allowed to add on new classes as they see fit. Yours may be one of them)

What's the link to your regions website?

Your definately not suppose to be in SS but you could probably get away with it at a regional level. You should probably be in SM2 due to the stainless lines, because if I remember right all you can do to the brakes in ASP is change the rotors/pads to another stock size rotor/pad(slotted/crossdrilled).

But I would probably just shoot for ASP on a regional level.

Here's the link to who runs everything. Small car club, so small site. http://ccsportscarclub.org/
Thanks for the advice on the tires. Those seem to be my single most limiting factor, besides me. I was able to get consitent and shave a little bit off my times as the day went by, but I was wanting to take advangtage of my power more. I'm running goodyear all season H rated tires right now. I drove my friends virtually unmodded miata, and even that was hard to control on all seasons. I thought the 140s was the least treadwear according to the rule book. A guy at the event said 100s for most street classes.

For removable numers and anything needed for autox try SoloPerformance Specialties. Here's their link: http://www.soloperformance.com/ they are really good people and service is excellent. They recently purchased Solotime so they now also have a full line of reuseable declas and stickers. The company is run by autoxr's and they sponsor the MidDiv events and well as numerous other midwestern events.

Unless something has changed drastically in street prepared in two years time, braided stainless brake lines are still legal there.


Edit. Double checked it for myself.

from 2006 Rule book in the Street Prepared allowable modifications...

15.6 BRAKES

Emphasis on "any" in the first line. Sorry for the red, but it pasted in a funky color for some reason.

SPICcnmGT

Yeah you're right.

Also good tires will be your best upgrade by far, that is besides seat time. If I was you I would run a season on street tires then next season get some good sticky tires. Street tires are usually easier to find the limit of, and will give you more time driving your car right on that edge giving you a better feel of the limits of the car.

2nded.

Ok, it doesn't look like you have classes different than what's in the rulebooks. So the classes would be ASP or SM2.

What is a sway-bar brace? The strut tower brace is allowed in SP (as is your engine torque brace, assunming it has spherical bearings at each end), but I'm not familiar with a sway-bar brace?

Larz

It's offered by racing beat. The sway bar mounts on our cars can crack, so this beefs them up and provides suppport. about 90 bucks and really easy to install.

Umrswimr

In which case it's not legal in SP... No chassis bracing is allowed except a strut tower brace and a rollbar/cage. Not that anyone would notice (and even if they did, I doubt they'd say much).

Specifically, secton 15.7:
...Non-standard lateral members whch cnnect between the brackets for the bar are not permitted.

Chadwick

Your mods put you into SM2. The Racing Beat reinforced swaybar mount does not follow ASP rules. "Non-standard lateral members which connect between the brackets for the bar are not permitted." There are other reinforced mounts that can be used as they do not connect the 2 mounting points.

Larz

Like the ones that RE sells?

Chadwick

iTrader: (12)

Never seen the RE mounts, the ones I use are made by Tri-point and sold through Mazdamotorsports.

Section8

iTrader: (6)

That sucks (but understandable from a rulebook view) since that piece does nothing for performance.

Larz

Yeah it's completely for reliability, along with my downpipe (but that does give some power, so I understand that). I hope what mazdamotorsports offers can keep those mounts from cracking. What about differential braces?

Umrswimr

Some people have been known to run a DP in SS, even.

A diff brace is definately not allowed in SP. You're stuck in SM2.

Section8

iTrader: (6)

It will help, but the best way to keep them from cracking is to replace them with the Widefoot mounts, they completely replace the stock mounts and reengineer the way they work.

Section8

iTrader: (6)

I ran a DP in SS in my first season of autox, mainly because I didn't know any better and the region was really lax. I switched to ASP after that season.

I've done this, they are engineered well, they're the way to go, and they're stock legal.
