Default Getting Started in SCCA Autocross

Given the sorry state of our local Los Angeles BMWCCA autocross, here's some help getting your car classed for the Sports Car Club of America (SCCA) autocross (also referred to as "solo") if anyone else wants to join me in running the SCCA events.

Join SCCA

First, you'll find it very helpful to JOIN SCCA. While not a requirement to run locally, there is a $15 discount for each event to SCCA members here in Los Angeles (member price is $25, non SCCA is $40). So, if you do this a few times you'll pay for your SCCA membership. Having a membership also allows you to then get a points card (a whole other mess I'll explain in future posting). For now, let's just say it would be a very good idea to join SCCA if you want to run their events.


Classing


The following isn't meant to be all inclusive, but rather a basic overview of the SCCA Classing process. The 2007 SCCA Solo Rules (PDF link)dictate explicitely what can and can not be done to the cars in each class and which cars can race in which classes.


Stock -> Street Touring -> Street Prepared -> Street Modified

Classing generally follows the path outlined above, with each class generally permitting more modifications (the major exception being tires).


Stock Class
COOPER = H-Stock (HS)
COOPER S = G-Stock (GS)
05/06 JCW = B-Stock (BS)

Permitted Modifications
  • Any Struts - including adjustable damping
  • Any FRONT swaybar
  • Panel Air Filter
  • Cat-back exhaust
  • Harnesses (Quick-fit or similar) and C.G. Locks
  • Wheels must be stock size and stock offset within 5mm. This means 15x5.5 and 16x6.5 for the MC and 16x6.5 and 17x7 for the MCS.
  • R-compound Tires - Hoosier A6, Kumho V710, or similar. Street tires are also acceptable, but won't be very competitive since race tires are permitted in this class.
  • Brake pads may be replaced
  • Spare tire and tool kit may be removed
  • Roll bars or roll cages may be added
  • airbags may not be removed
Basically, that's about the extent of the modifications that can be done. Lowering Springs, Rear Sway Bars, camber plates, camber links, cone filters, lighter seats, interior gutting, headwork, cams, engine dampeners, USS, Strut Braces, BBK's, brake stiffeners, slotted rotors, etc..... ARE NOT PERMITTED IN STOCK CLASS.



Street Touring
COOPER = Street Touring Stock (STS)
COOPER S = Street Touring Extreme (STX)

Permitted Modifications
  • All of the STOCK class modifications with the exception of tires
  • Tires in street touring must have a wear rating above 140
  • Tires may but up to 225 wide in STS and 245 wide in STX.
  • Wheels may be up to 7.5" wide for STS and 8.0" wide for STX
  • Coilovers, rear swaybars, camber plates, camber links, are all OK in STS.
  • You may have non stock seats, but you must still have the same number of functional seats. This means you can not gut your interior, but you may put in lighter racing buckets if you'd like.
  • The air conditioning may be removed.
  • Cone filters are acceptable
  • Spoilers/splitters may be added
  • cross drilled/slotted rotors
  • lightweight batteries are ok as long as voltage remains the same
  • batteries may be relocated
  • Limited Slip Differentials may be added
Street Prepared
COOPER = F Street Prepared (FSP)
COOPER S and JCW and JCW GP = D Street Prepared (DSP)

Permitted Modifications
  • Anything permitted in Stock or Street Touring is basically ok in Steet Prepared.
  • Race Tires may be used
  • Any wheel width, size, or offset may be used
  • Cross drilled and slotted rotors are ok, BBK's are not.
  • Bump stops may be altered or removed

Street Modified
COOPER = Street Modified (SM)
COOPER S = Street Modified (SM)

Permitted Modifications
  • All stock, street touring, and street prepared modifications are permitted.
  • IF YOU HAVE AN MCS WITH AN AFTERMARKET REDUCTION PULLEY YOUR MINI IS IN STREET MODIFIED.
  • Gutting of the interior is permitted
  • Windows may be removed
  • Wheels up to 12" wide are permitted.
  • BBK's
  • Cams and head work



*** IF YOU HAVE A JCW GP: currently the only class you are permitted to run in is DSP

What is a Points Card and why do I need one?

A points card is used to assign you a number for the year. This allows you to do a few things:

1. Run in the points series to be ranked in the final year end class standings.
2. Being a part of the series makes you eligible to trophy in your class for the year.
3. Having an assigned number also lets you get magnetics made with your assigned number (numbers must be at least 8" tall). NOTE: Soloracer.com is a good source for numbers and class letters
4. In Los Angeles, having a points card means you can pre-register for championship events. It also can give you registration priority for practices.

In short, it's a good deal that allows you participate more fully in the events.

What is a "club"?

Basically to get a points card, you'll need to designate that you belong to a "club". This club will be designated to get your points should you place well. Some clubs are marquee specific (for instance Team BLEW in SoCal is for Subaru owners).

I chose to join team No Bucks (No $) for the following reasons:
1) I liked the No Bucks name and the No Dues, No Problems mentality.
2) Gio was one of the heads of the No Bucks club.
So far, so good. I'd recommend No Bucks to anyone else who wants to get a points card.


For Los Angeles Autocrossers:

Follow this link to check to see what numbers are available
Then follow this link to complete you points card application
Once you have a points card follow this link and you can register on Solo2.com (the website for the L.A. SCCA)

What is PAX?

Basically the PAX system allows you to compare drivers in different classes based on results of national level drivers in each class. The PAX results are essentially a bench racing index that allows for a look at who was the best driver on any given day regardless of what class they ran in.

Here's a pretty good explanation of the PAX system NOTE: the link has the PAX index from a couple seasons ago. The 2007 PAX index is posted here

I'll answer all of that above in the two place holder posts. If there are any other requests, post them and I'll post up some answers as I get the time.

just for a comparison...
have you ever seen street mod run? if so, what kind of cars do you see in that class? and/or perhaps a link to a results page... times would be interesting to see.

RE: Street Mod Local Competition (Los Angeles)

Glen, see this pdf for the most recent results (street mod is on page 8). Ignore the bottom half of the field in SM that DNF'd. There were a lot of first timers out that day. The thing to look at is the top of the field.

For comparison: the fastest time in SM was 66.089 That was about 2.5 seconds faster than the fastest time in H-stock and about 3.5 seconds faster than I was that day. Keep in mind that this is pretty tight. Normally the gap between H-stock and SM would be greater.

BBKs should be STX legal as long as they attach to the same holes as the stock calipers.

its really the same. what car, the subie? its like this: stock lets you change very little, some electrical, catback, and tires. street touring is suspension mods with few power adders (CAI), but on street tires. street prepared is a few more things but basically street touring with slicks. street mod is basically an anything goes type of bracket, boost modification and ecu control gets you here... this is where the big power lives.

that's not entirely accurate but a decent overview. tell us what car and we can help more.
