How much seat time do you have? If you haven't autox'd for at least a year or two then the only thing I would recommend is seat time. If you have autox'd extensively (then you probably wouldn't be asking these questions) is get a month or two in the car to see how it handles compared to whatever your previously owned/raced car did.
The only thing I'd concentrate on right now is tightening the nut behind the wheel ( :lol: ) and regular maintenance items (upgrading to higher durability units if available) to ensure the car is in good working order.
Most importantly, have fun and make sure you bring something to the sport, be it an enthusiastic attitude or whatever!!

I agree, seat time is the best "upgrade" If you never autox before a school might not be a bad idea, check around you may find one local.

As to make the car do better lighten the car at nearly all costs. Lose the A/C, interior, sun roof, power stuff, and even replace the glass. Then get aluminum lower control arms (need to be replaced every so many years), polyurethane bushings all around, rear control arm eccentric bushings and fresh bearings among other things. In SCCA classing, an e30 will need to be highly modified to be very competitive and in that case be prepared to buy a trailer for your car, it'll be unstreetable. If you don't want to do all that it doesn't mean you can't have tons of fun autocrossing it, you just won't be at the top of the competitive group.

Oh and by the way, you'll need alot of spending cash.

I would make sure you don't have any worn out suspension parts and that the engine is in good tune.

Cool Im in the same boat, wanna autocross

Kool, I'm asking my self the same questions.

I ran a BMW 2002 once before autocross.
Friend was using it in SCCA ITA class.

I just got this 87 325is running straight, fast and true.

I'm going to read the BMW owners club rules and other local club rules first and see where to go from there.

SCCA solo may be beyond my budget for now.

I'm thinking Biltien sports
Eiback springs and sway bars.
Eurathane bushings.
15" rims 45 series tires.
loose heavy seats, AC, etc,
We stripped a ton of weight off the 2002 scraping the gooy ruber like dampening insulation stuff off the floor boards.


for starters...


hmm I think go look for the rules right now.

Good luck.

Cheers,
RIchard

San Diego Autocross rules?

Follow up:

Here are our local rules.used:

I think I'm gonna drop in some Bilstein Sports ($$) and run in stock class.
Cheapest way to get started...:
Maybe a cold air intake? Keep the MAF?
Already got an aftermarket CAT, hope its legal?

-----------------------------------------
Classifications: Stock class may run any size wheel, any brand of shock absorber, any air filter, pre-throttle body intake or cat-back exhaust system. Any other modification, including but not limited to springs, "R"-compound tires, and engine management chips will be considered modified. We use the honor system, please class your car accordingly.

A: 4 cylinder stock MS: All ///M cars, stock
B: 4 cylinder modified MM: All ///M cars modified
C: 6/8/12 cylinder stock MC: Mini-cooper (normally aspirated and supercharged)
D: 6/8/12 cylinder modified
X: All non-BMW’s
--------------------------------------------

Cheers,
Richard

Smile Oh my God what fun! drove in a SOLO 2 Autocross!

Had the car 2 weeks.
put in about 40 hours of work $300 +- parts and tools.
One trip to mechanic $1000 even.
Put a velcro strap on the battery.
Bought an HJC motocycle helmet, cheaper, $130
(Had to be SNELL95 or better, my old one was SNELL M90 SNELL M2005)

Off to the races. B)
SCCA D Stock class (Novice )

What a blast.
Now I'm broke. ha ha
Cant wait to do the alowable mods and run again.

Car was faster than I expected stock.
Driver was slower than expected. ha ha

New shocks
strut sttress bar(s)
new way bars
Air intake?

Anyone know of a good cold air intake system.
Hard to find.
Best one Ive seen is from autohauz AZ, reuses the original MAF. drops right in on original mounting points (I think with the original dampers which are a must) and has adapter to MAF, square to round hole.
BMP makes one with its own weird mounting.
Ive seen Better loking lighter ones which replace the MAF? bolt right into the boot or throttle body?
I'll keep looking, askinig.

Cheers,
RIchard

Man those stock clas restrictions are awesome. Here in NY, only OEM replacement stuff is allowed in stock class. Not even exhaust or intakes.

Glad you like it. Just don't go broke!
