E30 in SCCA

[madformx5]

I was curious what classes e30's run in for SCCA solo II? I was reading in my Bently manual that these cars do not have camber adjustment without buying something that I cannot remember what the name of it is right now and when you buy it you can only get 1/2 degree of negative camber at the most. Thanks!

See Appendix A:

It depends on the specific model.

In stock form you can adjust the toe in the front. That's about it.

FWIW a set of camber plates will add the adjustment you are after. And they are legal in everything above the stock classes.

Yep. You can usually get -3.5 or so max negative camber with stock style springs. If you want more then that, you'll need smaller diameter springs (like coil-overs, 2.5")

I thought you could use BMW specified parts, and BMW has specific adjustable RTAB's for E30's in the manuals. So they are legal. Correct?

I had have to peruse the rules, but I thought that's what I remembered.

BMW did indeed make "crash correcting" bushings for both the rtabs and the front upper strut mounts. I've only ever seen the front ones for sale, though, and they are like 3x the cost of normal mounts.

To the OP, I'm actually running in STX right now. If your car has a factory LSD, then it will jump directly from the stock class to STX if you add any class-changing mods to it. At least, that is the jump I made.

[z31maniac]

^There are still some mods you can do and remain in D Stock, you don't just automatically jump to the street tire class. But an E30 isn't going to be competitive in D Stock.

I don't believe you have to use the BMW bolts, but since BMW specifies the use of them in the service manual, they are legal.

*going to read rulebook*

13.8 E

If authorized by the manufacturer, the use of shims, special bolts,
removal of material to enlarge mounting holes, and similar
methods are allowed and the resulting alignment settings are
permitted even if outside the normal specification or range of
specifications recommended by the manufacturer. If enlarging
mounting holes is specifically authorized but no material removal
limits are specified, material removal is restricted to the
amount necessary to achieve the maximum factory alignment
specification.


That doesn't indicate to me it has to be the stock stuff, AKD adj delrin RTABs.

This is interested information guys. Thanks. If anyone has anymore info I would be interested in reading it.


88 325is. DSP autox car. DSP74 I would be interested to hear more about your car.

OE Offset ball joints were available for e30s as well as correction plates...

Not that it addresses any of this.

[gearheadE30]

Sounds like a good setup DSP. Most of that you can do in STX; why not race in that class?

[DSP74]

I'm kind of kicking myself for not keeping that in mind.

FWIW all the de-optioning I did=manual windows, sound system delete, trunk tar, OBC delete etc is only legal in Street Prepared. Also cars delivered with A/C will have to have it in S/T classes next year. And that stuff while not flashy was a little on the expensive side, as well as being quite a bit of work.

FWIW I really want R-compound's as the fun factor goes WAY up.

I run STU cuz I'm craaaaaaaaaaaaaazzzzzzzzzzzy

[DCColegrove]

Off the topic a bit here...

Is there anyplace I can go to catch up on all the popular (new to me) e30 racing classes and their respective rules?

I left off quite a while ago and it seems that an amazing amount classes are targeted at less costly race cars has popped up since.
