I am looking at getting a set of rims that have 4.25 inches of backspacing. The rims are 17x8's and I have a 86 vert anybody know if this will fly? I also have a turbo coupe rear I want to put in but I am pretty sure they will not work with that right? Any help would be greatly appreciated
hey brad...with the turbo coupe rear end it would set the wheels out 3/4 of an inch more, so that would be like a 5 inch back space on a stock rear end. might work..but you would need 5 lug axles...ones off a 94/95 stang will work.
OK I am getting twisted up a bit here. If stock backspacing is 5 inch and I want to go to 4.25 will the rim stick out farther or tuck under more with the 4.25 Also will the 96-04 front spindles work or just the 94-95. I saw some stock 79-93 spindles on Ebay that said all you had to do was change the hubs and rotors on the front that isn't right is it?
Answer to your question is it'll stick out 3/4" farther if the wheel is other wise the same width.
Spindles come in several variaties.....
'79-'86 spindles were all pretty much the same.
'87-'93 V8 spindles are different than the non-V8 spindles (which are still that same as '79-'86 spindles). The V8 spindles from '87-'93 are beefier to support the larger brakes Ford placed onteh V8 cars startign in '87.
'94-'95 spindles are the same.
'96-'04 spindles are 8mm wider than the '94-'95 spindles for reasons I can't remember.
