V12 Inspire

I'm hoping to race in the Time Attack 2 class (lightly modified cars, still street legal, still fully caged, etc.), so besides removing a lot of the interior (black leather interior is nice, but essentially useless in 1,000°F Texas weather), and caging it up, what other modifications would you guys recommend so that my TL can actually look good and go decently fast going up the 'Peak without embarassing myself around what will probably be mostly Porsche 911s?

Ninja Edit: sorry for misspelling "Planning". On iPad, I have sausage-fingers, and I commonly make embarassing typos. Doesn't help that I cracked the screen a few months ago :P . Also, I know I'm gonna need wheels and tires, so I already have that planned out.

a really good suspension setup with dampening, sway bars, lighter wider rims, good tires, a J35A3 swap with accord trans, headers/exhaust, a way to deal with heat soak.
