I believe the rears are 5.25 bs and the fronts are 5”. The fit is great to me because it squares up nicely on the car. I wish I had the cash to order custom offset wheels because I have plenty or room for more tire inside on the rears!
Just picked up 17's for my 66 Skylark, 17x8 front & rear with 4-1/2" back spacing (zero offset), 245/45/17 tires with almost 5/8" clearance on the rear wheel wells.
I really dig the Torq Thust wheels I saw at a recnt car show. Do you guys think these would fit? My car does have a 12 bolt already in it. I am not sure but it might be the narrow version. I am currently running the 5x8 rear rally wheels , I dont remember the back space but they might have custom backspace since I can fit the 275 tires with no rubbing. 18x8 4.5 in backspace for the front 18x9 5 in backspace for the rear what size tires would look great as well? I did borrow an 18x10 5.740 in backspace and the wheel fit, but will not fit once a tire is mounted. Just needed 1/4 of an inch to make it fit.
