I just put 18x8's with 4.5 inch back spacing on the front with a 245x40X18 and 18x9.5 with 5.25 back spacing tire is a 275x35x18 mounted on Boss 338's Gray's. They look awesome. Suppose to pick up car from the body shop Wens day night/Thursday and finish the exhaust and install the 3:91's for the car cruises this week end. Will post picks. Car is a numbers matching 340 10.5.1 Barracuda, black with charcoal Grey 71 bill broads.
