Necessities to prep a 4th gen for AIX?

Hello all,

Im looking for some guidance on what is necessary to prep a front or mid pack 4th gen f body for AIX. I am not new to f bodies, as i currently have a '95 z28 with a H/C/I 370lq9/t56 that is prepped for autocross/track days in the manner of koni yellows, strano springs, watts link, Brembo 4 piston caliper in front, all new bushing/balljoints, all the other usual suspension components. Ive decided a goal to get into AIX can be attainable because I am not too far off of the mid ohio track record according to their website. Mainly what i would like to know is:
What kind of power and weight does most of the competition have?

I have read the CMC/AI/AIX rules, but still have a few questions.

What is considered a NASA legal cage for AIX. Is a 6 or 8 pt sufficient?

I realize i would gut the interior, but I don't know if the fixed back corbeau seat I have is legal, I assume it has to be a metal type seat?

On the website regarding rules, you MAY use lexan for front windshield and rear window. By the cars ive seem I assume lexan is REQUIRED front and rear?

I see how CMC and AI are required to run toyo tires, is AIX open to any tire?

Thanks for any and all help.

Some mediocre autocross clips!

Im bored to death here at work so i figured id share a couple clips with everyone. The car is a 95 z28 with a lq9/t56 swap and 4.10s. Engine is forged pistons and rods with stock crank, cam, ported heads and ported fast 102, 11:1 comp.

Suspension upgrades include a bmr road race k member, all new moog bushings and ball joints, kyb shocks and struts, strano springs, adj pan hard bar, brembo big brake kit (same caliper as 4 piston ctsv), two piece rotor, hawks pads, and rear lca relocation brackets. Stock sway bars and all stock control arms, stock torque arm. Used 315/35 17 hoosier a6s on all 4. The car struggles with loads of understeer on corner exit. The alignment currently sits at -1.75 camber both sides, 4.5 ish caster and -.125 toe both sides. Im looking to reach about 2.5 degrees of camber.Yes tons of mods are in my future, but i still manage to be competitive in A class (miami valley sports car club nasa). Yeah i know it puffs blue smoke lol...
Hope the iphone videos arent too bad.
