Re: Autocross FAQ

you're good to go for ST from those mods. Its borderline whether or not the throttle body mod is actually ST legal, but nobody will say anything about it.

The subwoofer will really hurt you b/c of weight, but I don't think its technically illegal.

Re: Autocross FAQ

Does it use line-level or high level inputs? I take my subs out before every race, it takes about 10 minutes and is a bit annoying but it's totally worth it.

well i've got my entire system attached to the sub box, an amp for the sub and an amp for all the door speakers, so all the wiring is run to the box, i may remove the amps from the box so all i have to do is disconnect the sub

Re: Autocross FAQ

What I did was get a couple large molex connectors at Radio Shack and cut the wiring for the amps a couple inches from the rack, and routed them through the molex quick-disconnects (just all the signal wires, not the power and ground wires). So I still have to unscrew those big wires from the terminals, but everything else just as a quick clicking plug.

Re: Autocross FAQ

yeah I'll have to look into that, I should just have to remove 1 power wire, as it goes into a distributor block and splits it between the amps, and the RCA's are pretty easy disconnects anyway.

Re: Autocross FAQ

So my HKS exhaust (which deletes the 2nd cat) puts me in FSP right away?

Current list of mods:
Simota SRI
Progress Springs
17x7.5 wheels with street tires

Planning:
New shocks
F/R (or just rear) sways (MS3 or Hotchkis)

First time out is probably going to be this Sunday. I know I am no where near being competitive but just want to know where I stand in a class.

Re: Autocross FAQ

As I said, TECHNICALLY, yes. But it's such a minor thing that no one is going to care at all, until you start getting super competitive. If you were running 9" wheels with 255's you would definitely not be allowed anywhere near ST, but with such a tiny discrepancy, it really won't matter. Just have fun

Actually, i think its ok to delete the 2nd cat in ST, it doesn't say you need to retain all your cats.

Re: Autocross FAQ

I'm going to be doing my first ever autocross in late July with CART in CT. What do you guys recommend for tire pressures on the Speed 3?

I also know that you need to take everything out of your car. Do you guys usually leave your floor mats, spare, ect at home or do you take them out when you get to the event?
