The TMS laps were great. We were all autox racers so being paced at 80 was disappointing, but we'd probably have killed ourselves if we could go flat out

I think my car has enough grip that it felt like I could have taken it to at least 140 with reasonable safety but my car has that big spoiler and the trans-am body is actually pretty decent for aero.
The only mods I've done is adjustable race shocks, K&N air filter, iridium plugs because swapping out f-body plugs sucks, and a high performance muffler. Within the stock category, I'm allowed to also upgrade the front swaybar and use any cat-back exhaust as long as I use "stock" style cats. LS1 F-bodies are deliberately intake and exhaust restricted to ensure that from the factory they didn't compete with the vette, so you can get back nearly 20hp with a simple free flowing air filter and cat-back exhaust. No intake work is allowed, so I just have the filter and it noticeably improved throttle response.
I like the white camaro rims

It sets off the red paint and gives it a bit more of a race-car look. They have identical geometry to the stock rims and they're really cheap ($60 each if I recall correctly) so they're an obvious choice to use as my race set.
4 full size tires in an F-body...
Slide passenger seat full fwd and tilt forward.
Slide drivers seat fwd about 6 inches.
Fold down rear seatback.
Place down old blanket to protect interior.
Stack 2 tires, level, behind the passenger seat. The top tire can go slightly farther outboard than the lower tire. Place towel between tire and ceiling to avoid black scuff on ceiling liner.
Using another towel to protect the passenger seatback, fold it back upright and slide it back until it touches the tires, holding them from sliding around.
Behind drivers seat, place one tire angled up so it's leaning on the two tires behind the passenger seat.
Protect driver seatback with towel, and move drivers seat until it also touches the tire, holding it into place.
Open liftgate.
Place tools in rear covered cargo compartment. Do this BEFORE putting last tire in otherwise you can't open the covered compartment very far.
Place last tire on center of raised rear deck, touching the tires up in the rear seat area.
Carefully close deck lid making sure tire doesn't hit glass. If you pop the glass out by slamming the lid shut on the tire, it's your fault not mine

This works with the standard 8.5" wide tires. I know it works with the biggest tires you can reasonably put on 16" rims, and it should also work just fine with the 17" firehawk or older vette rims, but the clearances might be a bit tighter. Worst case, you can put one tire up on the front passenger seat but I never had to do that.
I worked this out so I wouldn't have to tow a trailer to and from events since it was at least a 3 hour drive each way. On the other hand, if I had a trailer I could just keep all the crap in the trailer and loading/unloading before and after events would be a lot easier. I think I may end up just getting a small trailer kit and customizing it for my race equipment. That way I can keep other stuff like replacement brake discs and more tools/parts in there just in case I break something on race day.
