Cragar SS Wheels & SSBC Calipers

I've wanted to swap my Keystone Classic 14" wheels for a set of Cragar SS 15" since I've owned my stang (>25 years). Finally pulled the trigger and ordered them locally.

But, the fronts hit the calipers. I had installed a SSBC (Stainless Steel Brakes kit) more than 15 years ago. I thought those calipers were the same Kelsey Hayes 4-piston ones used in the late 60s. I was really surprised to find out the wheels didn't fit.

Anybody have an ideas that could help (or even just make me feel better!)?

My second option is to just go with 15" Keystones. I like 'em; just not as much as the Cragars.

Thanks.

Where do the calipers hit the Cragar wheels? What year is your car? Which SSBC kit did you install? I have 15" Cragars on my '66 with the factory installed front disc brakes. There is plenty of clearance.

Sorry, should have included more info. Car's a 68. I don't know how to answer "which SSBC kit". The calibers are 4-piston and they have the external brake line going between the two halves of the caliper. Other than that, it was so long ago, I don't recall.

They still have the calipers on their website. Pretty sure its this one:
https://ssbrakes.com/i-10093495-1964...let-a62-2.html

I thought they were the calipers that Ford used stock.

I didn't see the fit issue first hand. The shop called and said the spoke hits the caliper near the point where the spoke connects to the rim. Sounds like the spoke angles in toward the inside of the wheel.

The Cragars were the 15x7s.

I find it hard to believe the Cragar SS's don't fit with your disc brakes.

It really doesn't make sense. Cragar SS's have been used for decades on everything.

BTW, your '68 should have single piston calipers and not 4 piston calipers. The 4 pistons were used from 65 to 67.

Nothing wrong with having the early 65-67 calipers on a '68.
I ran my original 66 GT calipers on my '68 for years.
Interference of the earlier caliper with the Cragar SS wheels
surprises me too. Seems like I've seen those two together
successfully before.....

You need to go look at the interference yourself. I have seen several instances of wheel-caliper interference that was easily remedied with a little bit of judicious use of a grinder.

Huntingky, are they 14x6? The 15x7 has a 4" backspace and the 15x6 is only 3.25".

I'm going to go look at the amount of interference tomorrow, but I'm pretty sure the 15x6 will work. That's what I'm hoping, anyway.

Yes, they were 14x6 (I believe, this was many many years ago), wheels long gone now.

My Cragars are 15x7 with what I measure as about 4" backspacing. You can see in the attached image that I have a healthy 1/4" clearance to the caliper (indicated by the red line).
