I went to a Middle GA region autocross with a friend in his Mazdaspeed 3 this past weekend (mental note: reapply sunscreen after lunch break) and it got me thinking about possibly autocrossing a Protege, though likely not mine since it's a lolomatic.
I see in the SCCA rulebook that the Protege and 323 are both in H Stock class, which is where Civics, non-S Mini Coopers, and a bunch of other odds and ends are classified. Are BG-chassis cars competitive in stock class auto-x? It looks like you can change the following:
- Shocks: It looks like you could use the ZX2 S/R struts, as modifications to allow use of aftermarket shocks are allowed as long as you don't alter the adjustability range of the suspension.
- Wheels: You have to keep stock diameter, width, and be within 0.25 from stock offset.
- Tires: You can use any size DOT tire, as long as it fits on the stock size rim.
- Front anti-roll bar, cat-back exhaust, brake pads+rotors (as long as you keep stock sizes), and air filter element (no cone filters, just panel)
You can NOT, however, use poly suspension bushings. Only OE rubber suspension bushings. You can use poly bushings on the front sway bar, though.
Or if we aren't stock class competitive, how about STS class? Don't think we'd be challenging the 89 Civic Si Hatchback dominance, but would we be bottom of the barrel?
Wild speculation, blind guesses, and jumping to conclusions are, as always, welcomed.
