I'm new to this forum. I live about an hour west of Chicago. My project is a 1975 Pontiac Trans Am. I have owned the TA for 17 years. I am new to going fast around corners. Used to just be a straight line guy. 1/4 mile is 10.50@116mph. One autocross event and I am hooked. Currently my TA is getting a Heidt's sub frame and rear 4 link. Brakes will be Wilwood 12.19" with 6 piston calipers. Tires are Rushforth Live wire. Nitto 555 245/40 and 285/40 tires. Engine is a 462" Pontiac making 562 hp.
