i have been looking at wheels and tires for my 67 fastback. hard decission... for now im ordering new front and rear stock suspension that is 1" lower and im putting a 8.8" rearend in it. i have front spindle and brakes from a v8 car so its already 5-lug and im going to do a 5-lug conversion in the rear. im doing this just to get the car driveable (after 4 years of not being able to drive it). future plans include an irs unit out of an 03 cobra, tcp or control freak type front suspension, and baer brakes. i will lower it more if it looks like it needs it. im looking at 18" and 20" wheels that are made by coyswheel model c-5. i think 18x8 is the widest for the front so can i fit an 18x9.5 or 20x8.5 in the rear, what backspacing would i need. or 18x9.5 in front and 20x10 in rear would be nice maybe. i can add fender flares for clearance on the outside but i dont want to mess with anything on the inside. sorry its so long i tried to put all info you would need. ..thanks for the help..
