I took my '06 cpe 6 spd to autocross this weekend and learned the limits of my car. Unfortunatly I killed a few cones in the process. I had some great times and crushed a couple mustangs in F stock. I usually autocross my sons Miata so the G was a completely different animal.
Any suggestions on what product should I use to get the scuff marks off the front of that car without damaging the paint? Thanks.

 

i tape my bumpers before going to autox.
you just have to wash your car with a microfiber towel and rub it off.

 

Or, if you don't want to tape them, I used a removable bra, which is now for sale:

I nail cones a bunch of time not perminate damage yet. I might blue tape it next time tho

 

If on the surface and a gentle polish like 3M Scratch and Swirl won't touch it...try some Detailers Clay like Clay Magic.

If scratched...take to a detailer. They'll use some 2000 grit paper, and light cutting compound, glaze and wax to bring it back perfect.

Bizarre the G Sedan classes higher than the coupe...I'm an Auto X guy and just picked a 6MT sedan. Trying to decide between DS and STX.
