But what about brake rotors, can you use after market, as in slotted and/or cross drilled rotors (stock diameter of coarse)? Oh and did I also see that the traction-control can be dis-abled? The last time I ran Stock classes, the cars were just that, stock with very limited R-Compound tires in use. In fact I won an E-Stock and D-Stock club Championship with totally stock vehicles, only changed tires.

Hate to sound so stupid but, went Road Racing years ago and kinda lost touch with the Auto-X side of things, any help would be great!!

The rules for stock class have not changed significantly since I started in 1993, the only change I have seen in my times is the recent allowance for front OR rear swaybar changes.

The TRD rear bar has always been stock class legal for the 07'-11' Yaris, it is a factory port install option (good news for 12' cars, this could get added to your options list soon). The current rule however now allows you to use any rear bar. Or in the this case you could use the TRD rear bar and change your front.

Any air filter element in the stock box may be used, or you can run without if you want.

Any shocks up to double adjustable, must be within 1" +/- overall length of the OE shocks, and perch must be in the stock location.

Crash bolts can be used, but only the OE or equivalent, you cant use the cam style.

Traction control can be turned off via the factory switch, or the factory service back door method. You can not unhook the sensors, or mechanically disable the system in a way not intended by the manufacturer.

Any brake pad can be used, pre-1992 cars can replace rubber brake lines with braided, rotors must be OE or equivalent - they can not be driller or slotted.
