Wheel / Caliper Issues
#1
Hello All,
 I just installed a Wilwood brake system w/12" disc. and my vintique 54 series 15x8 steel wheels with 4" back spacing are hitting my calipers  right at the first hump. Even with a spacer.

A= 1/16
B= 6 7/8
C= 2 3/8
D= 2 15/16
E= 4 1/2

I have talked to tech support at Vintique and at Wilwood with not much feed back from them.
My question to the forum  is:

Will Magnum 500 mags work with my brakes?
Will going from 15" to 17" help me?
Not having different wheels to try and just going by approximation / guessing is driving me nuts. (short trip for me)

Thank you ,
Bru

Doh!
Hate it when that happens.
My guess is that you will have to go to 16's or 17's. If you head way north on I5 I have a 17x8" SN95 Mustang wheel you can have. The backspacing it totally wrong for your application but you could stack spacers or something to test fit it and use it as a mock up tool.

I had to go with 17's to clear my front brakes. Hurst Dazzler 17X8 wheels with 4.5" backspacing are probably one of the least expensive options.

Most places will not give you yes or no fitment answers once you have gone custom. Measuring it yourself is probably best.

Magnum 
Bentworker,

Thanks for the offer but I think you are a bit far north. You aren't pinned on the members map, but I believe you are up in Redding.

I was hoping the 15 x 8 Magnum's would fit. At least I could use my tires.
The way it stands,  I'm out 5 painted rims, 4 chromed poverty caps and 5 brand new tires.
Ain't life grand? Bouncy

ok this is more of a guess than anything but magnums have 4.5" backspacing, and by the looks of the damage they would clear. You don't need a brand new set yet, just check with auto shops or even junk yards all you need is one 15" magnum that's in terrible shape to try and fit.

Which Wilwood set did you get? I have Wilwoods in the front with 15" Magnums and no problem. In the rear i had another set of disc brakes that were touching a little. I ended up grinding a tad out of the caliper to increase clearance. The rears were one piston floater calipers so i would be less concerned grinding the outer half than with the wilwoods.

-Backspacing is not the problem, in fact I believe the problem would be worse with the added backspacing.
-Good suggestion about going to a junkyard and picking one up. I'll do that this week.
Thanks

I have the mustang kit and I did try to grind a bit off for fit. It's just way too much to take off
and they will only fit with the spacers.
 I had to stop my "make it work" train of thought and re think on how to make it right.

I was considering 140-11074 (12'') or 140-11073 (11'') if 74 doesn't fit my Weld ProStar
Which one do you have @tony_muscle?

73 modified Grandé 351C. Almost done. 
71 429CJ. In progress

I have the WIL-140-13477 kit. This kit has 11.3" rotors. I have the regular solid discs.

I have the 11074D 
I talked to Willwood about dropping down to a 11" disc since the same calipers are used with different mounting hardware.
They had no comment but according to there size chart I would get about 1/4" more clearance . Still not enuff if I want to get ride of the spacers.
