Dear Readers:
Sorry in advance for a long post here,
I know you can take the Granada rotor and have the snout turned down so it will fit older wheels, but can you remove the wheel studs and machine that surface down about .20 of an inch and the put the wheel studs back in? (width grind, not diameter like for the snout modification.)

I am asking because I believe that would then make your wheel sit in .20 of an inch further no?

I would assume that the lost space would not really effect the lug nut grip on the studs as that would still be eaten up by the thickness of the wheel mounting surface itself.

Biggest issue I think might be structural integrity of the stud mounting points. It looks relatively thick though, does anybody know, what are the general thoughts out there on this idea.

I am asking about getting the wheels to move inboard about .20 - .25 of an inch and thought this might do it. I have custom Bullitt Wheels from Wheels market.com that are 17x8 with 4.5" backspacing. The rears fit wonderful, however I think the fronts sit about 1/4 to far out and want to make them move inwards. I have plenty of room between the backside wheel lip and the upper control arm.

I know that the factory ford Bullitt's have 5.72 backspacing and people must use a 1" spacer to make them fit, (resulting in 4.72" backspacing). I have seen pictures and they look great. I don't really want to use spacers and bought these wheelmarket.com ones however they only have 4.5" backspacing and I want to move them in ever so slightly. I am in the midst of a granada brake swap and already did the Shelby control arm mod. I had this thought that maybe the wheel mounting surface on the rotor itself could be machined a little bit and then I would get my magical .20 or so of an inch move inwards.

Looking to complete this project soon so any help is greatly appreciated and will reduce my project time.

Thanks in advance.
Matthew

I'm sorry but modifying the rotor to compensate for the wrong choice in wheel backspacing is not the right way to fix the problem. There is definitely not enough meat in the rotor face to allow you to turn almost 1/4" off to correct for the wrong wheels. You might be willing to take the risk but is it fair to let all the other motorists on the road bear the burden of your bad decisions? When the rotors break and you kill someone in an accident replacing those wheels or rolling the fender lips is going to seem relatively cheap.
