Bill,

I have about 10 track days on the car. I did not get a clear wrap, so there are some minor blemishes on the front bumper. I would expect a clay bar would take care of most of this. There are no issues with he windshield, it has never been cracked.
-Sparco Seat, I am 5'9" and 170lbs. I have plenty of room, but it would depend just how broad your shoulders and back are.
-OEM Wheel are included in the purchase
-Harness is attached to the roll bar, and the sub strap is attached to the frame of the seat. I will send more images to your email.
-Bodymotion Racing, out of New Jersey did all my modifications.
-Suspension was going to be the next on my list. The car is quite capable on track, but if you went with slicks, the grip may prove too much for the factory suspension.
