stiffing up the chassis. i have not driven very many american vehicles lest a few. most that i have driven inspire the tail first type driving style. depending on how your car does, i would suggest larger anti roll bars (again depending on how you like your car). on my car i have the rear anti-roll bar larger tha the front. strut tower braces, and tie bars would be good too. roll bar gies some good stiffening and safety (make sure to get them tested). is the car lowered? perhaps a camber kit with some fine tuning to get your own feel. again i do not know the mechanics of the trans-am, so i dont know if any other modifcation for use would be needed to make room for other componenets. of course brakes are a must. a higher redline is always better to, but i dont think the trans-am could really handle it.
