SCCA Solo - Chart of Modifications by Class

[Xaeryan]

(I created a new thread for this since the old one was poorly named.)

In deciding on what SCCA Solo class to compete in, I put together a chart of class modifications I'd like to share with you all. The chart includes many common 1 series modifications, and is current with the 2012 rules:

(This is a temporary home until I have a better domain - bookmark this thread instead)

This chart should not be your definitive guide, but rather a first-draft; once you decide on a class, read the rulebook closely (get a copy here: http://www.scca.com/downloads) to make sure no modifications you have fall into any exceptions.

I interpreted the rules as best as I could, please correct me if I am wrong on anything. Particularly if you plan on competing in Nationals, always err on the conservative side for any gray areas and assume the modification is illegal until clarified otherwise.

Comments/suggestions/corrections appreciated. If you see parts that are not listed you think should be, let me know.

Happy racing!

Thanks, appreciate the link. Easy to find my class, although it seems strange that the M steering wheel would put me into a street prepared class?!

This is great.
Thanks.

Glad you found it easy to use! Unfortunately, the rules for the steering wheel reads like this in Stock:

Alternate steering wheels are allowed, provided the outside diameter is not changed by more than one inch from the standard size. Steering wheels with an integral airbag may not be changed.

And it's pretty adamant about the airbag part in street touring too:

I believe the intent of the rule is to avoid safety concerns with messing with an airbag. I don't think anyone's going to protest that change regardless of what class you run, but if you want it to be legal, since that wheel came with the sport/M-sport options, I think* you can swap in everything else from that option package:

*The fuzzy part then is, "the resultant car must meet all requirements of this Section"... is not changing the steering wheel a requirement that applies prior to or after the option package allowance? Nerdy reference: I need a M:TG rulebook to help me with the order the rules are resolved.

Ok, that makes more sense. It seemed strange that just a different steering wheel would provide me with any advantage.
