Fitting issues with Wilwood brakes and Magnums
#11
Mike,
I just checked mine. I thought that I had 6 piston but they are actually 4. At one time I was looking at the 6 piston ones but went to 4 because of fitment issues as I didn't want to go larger than 15" rims as I wanted to stay with TA Radials. I bought these brakes 3 yrs ago when I was accumulating parts so I forgot about the change I made. Rotor size is on mine is 11.3" so there is a quite amount of difference in rotor size with the 12.19 that you have. I checked the WilWood site and they say that Min wheel diameter for those rotors you have is 16". Unfortunately they will not work with the 15" Magnums.

Measure the height of the stack of washers.
Then you know exactly how much spacer you need and whether it works in the first place.
It depends on the width of your rims and tires.

I went out and got a bunch of washers and it took 6 washers which turned out to be 5/8" thick to get the wheels to clear the calipers. Everything else will clear (tires to wheel well) but not much thread left on the lug studs. I guess I could get longer studs somewhere, I'm afraid that's going to put too much extra stress on the bearings.
What do you guys think?

There's no replacement for displacement Rolleyes

Either use longer screws or adapters that come with their own screws.
It will put more stress on the hearings but you should be ok.
I have 40mm (1.5 inches) adapters behind my rims and they have modern 18 inch high performance tires on them which have tremendous grip and no bearing has ever given in although we have mostly very curvy roads and I drive like a maniac.

I used some Allstar Products studs and 1/2" spacers to fit my 18" wheels. They are P/N 44112 1/2-20 thread 2-1/2" long with a .619 dia knurl. Those were plenty long to use with the spacers and aluminum wheels.

How about getting or having some front rims made with the proper backspace?

"I love my Hookers!" and "Get some Strange" probably have a different connotation to non automotive enthusiasts!

Thanks Mike,
I'll give that a try today.

Hey Mike,
I have the exact same issue... did this work for you? How did you solve it
