Will 15" wheels fit over Wilwood rear brakes w/emergency brake built-in the caliper?

16.5 barley fit. 17" recommended . If you look at wilwoods documentation you'll see what the clearances are.

Kinda of depends on what rear differential. With the new IRS, you can go Wilwoods with 15" wheels, but not the parking brake. There just isn't room with the new spindle design to conveniently fit it in there. Several of us with this setup did either driveshaft mounting parking brake or hydraulic line lock. With old IRS and/or live axle, you can most likely fabricate the brackets to fit the spot caliper though.

I have 4 piston kits front and rear that fit under 15" wheels.

FFR Recommends 17" minimum, I will be buying 18" to have a bit more clearance. I have an IRS on my 33.
Using 15" Bogart bead locks and the Wilwoods do not fit. Only company that has a disc brake for a 8.8 Ford with the C clip eliminator is Aerospace Components in Florida. Luckily they are the same price as the Wilwoods.
I have the optional 12.19" Wilwood brake kit on my 33HR with an 8.8 with Moser c-clip eliminators and I'm running 15" Weld Racing wheels with MT wrinkle wall drag slicks. To run 15" wheels in the rear I had to swap the caliper with the integral parking brake for a Wilwood DynaPro 4-piston caliper (Wilwood #120-8538) and use a manual line-lock for a parking brake (Speedway Motors #910-31301). To get around the c-clip eliminators I mounted the caliper brackets on the inside of the bearing flange and used aluminum spacers to get the caliper lined up with the rotor. It's a robust set-up and looks like a kit supplied by Wilwood.
So Walter, if you want to run 15" wheels on the rear and still run a 12" brake it's possible using most of your Wilwood brake kit but there is no way those bulky calipers with the integral parking brake will fit inside a 15" wheel. And if you don't have c-clip eliminators it's even easier. The cost in brake system parts will be a bit over $400.

CVOBill, I am working on the '35 pickup and would like 15" wheels also. I have the FFR supplies 11.65" rear brakes. I just heard from Tony and he indicated I would need 16" wheels to clear brakes, but you got yours to fit with 15's?
He also indicated he used 5.5 backspacing all the way round, but I am having trouble finding these in 16" Torque Trust.
With full fenders he said 235 fronts and 265 rears are needed to fit.
Any helpful hints would be appreciated.

I just purchased 17" bullit style wheels for my 33 with the Wilwood brake kits and guess what? They don't clear the rear brakes! The just barely rub the top of the caliper. I couldn't understand why until i realized the 10 1/2" wide rear wheel actually has a jog or hump on the inside of the barrel so essentially my 17" wheel is a 15" on the inside. I didn't see that coming, ouch. After doing some research I find out that a lot of wheel manufacturers have this jog in the barrel so beware of 17" wheels too, they are not all the same. I had read a lot about offsets and back spacing, bolt configurations, hub bore diameter etc until my head hurt, but never read anything about barrel diameters. The fronts are fine with about an inch of clearance because the barrel is flat.
