Autocross and a 904 transmission

What’s the basic rundown on your set up?

-wheels and tires
-torsion bar diameter/rear spring rate
-sway bars
-shocks

I would mostly just make sure to do a thorough pre-check on everything before going, especially since you’re not going to be changing parts or anything. If you have adjustable shocks you might want to consider changing the adjustment. Tire pressures are important too, but with street tires you don’t want to get too extreme with the changes. You can ask other folks that are running what they’re doing for tire pressures, as it will depend on the temperatures that day, the tire manufacturer, etc. When I did track days with my motorcycle some of the track day providers would post basic tire pressure recommendations based on track temps and sometimes even break it down by major tire manufacturer, not sure if they do anything like that at MoParty.

For the auto, especially if it doesn’t have a shift kit or anything I would probably pick a gear and stay in it. It will depend on the track though. What shifter do you have? My Challenger with its 904 had a slap stick shifter, which would make it easy. With that I’d just put it in first, “slap” it to second when I got the speed up and then probably just leave it there unless there was some really slow corners. But an A-body shifter wouldn’t be quite that easy.

If it’s your first time or close to it though I wouldn’t get too crazy with car set up changes, just have fun, try to pick the brains of some of the more experienced guys. If you make any changes at the track, make sure to only change one thing at a time. But most of your improvement will come from you, not your car, especially early on.
