Billet Specialty F-body guys come in and help please. Here is the deal.
Have a set of billet Specialty Drag Lights on the rear and want to run a set up front.
The car is a 2002 TA
Rear: 9 inch Moser cut down 3 inches on both sides. Mini tubs on rear of car. I have a 15x12" Billet Specialty set of wheels holding 29.5x10.5x15's on the rear now with a 40 spline spool in the rearend. All that is worked out.
Front: I want to run 15x6" Billet Specialty wheels with like a 225 15 radial up front. I do have a Wilwood 11.75" brake kit for the front. The wheel for these brakes has to have at least a 14" barrel which the BS Drag Lites have.
What I need to know is how far from the wheel flange of the wheel is it to where the barrel turns from 13" to 14" on the 15x6 with 3.5" backspace. I think this will all fit just fine with a .250 wheel spacer but I am afraid the tire will be out side the fender a little.
Has anyone on here used this wheel up front with those brakes? I need your input before I install the brakes and order front wheels.
Before you tell me to just put skinnies up front keep in mind I am running a spool with the rear tires. This car will also have a set of 315x15 MT drag radials on the rear. they have 13" of meet on the ground. I want the extra tire up front to help turn the car into the parking lot. I also like the look of a wider tire up front as compared to skinnies up front. So skinnies are out of the question.
Thanks for the help.

I know on my skinnies which are the 15x4's I still had to grind the calipers on the 1.75 back space so if the wilwoods are any bigger in size, they most likely will cause bigger issues. I don't think that 1/4 inch spacer is going to be enough to get out from under that part of the barrel to clear them. You might have to run a 16 or 17 up front to clear the brakes with the barrel.
My buddy has a 71 nova with the wilwood brakes and aftermarket rotors and his Billet's fit fine clearing the brakes and all. His are the 15x4's with the 2.25 back space. I don't know if that helps any

This kit has smaller 4 piston calipers. The .250" spacer might be needed to clear the caliper from the spockes. The outer diameter of the assembly is 13.7". I bought them to try and fit a 15x6 BS rim on the front. But I am not sure it will do it and still line the front wheel up in the car. This whole wheel deal is begining to ps me off. I have not installed the brake kit yet. I would like to find out if anyone has done this before I do so if I need to I can send the brake kit back.
I have concidered running 17"s up front but I really want all the wheels to be the same size. A sign of my age I guess.
I am worried you are right that even with a .250 inch spacer I still cannot get the caliper into the 14" barrel, and any wider a spacer will push the front tires even farther out from inside the fender wells.
I should have cut the front completly off the front of this car and just built a whole new front end.

Did you look at the PDF instruction sheet on wilwood's site? There is a measurement diagram on there.

I honestly don't think its going to work. I had ordered the wrong ones when I first bought mine and I had the 2.25 back space. I grinded the **** out of the calipers before I realized that I needed the 1.75 back space. The question is, are the wilwood brakes smaller (closer to the center of the caliper) than the factory's? If they are, they most likely will fit. If not, only a 1.75 back space will work because of the step in the barrel. Also I know you are not going to order a 15x6 with a 1.75 back space, that would look like ****.
Edit: 15x6 only comes 3.5 backspace.

This is the brake kit I have. It is the .81" thick rotor not the 3/8" thick rotor. Wilwood recommended this kit due to the weight and speed of the car.

Yes this is a majoe issue for me.
What to do?
I will either have to run skinnies, or go to a 17" front wheel wich I might not need this brale kit for, but I do not want that look with 17's up front and 15's on the rear.
I could run a different brand of wheel all around for the street but then I have an odd wheel on the rear for the strip.
I dont understand why it would be a big deal for Billet to make a wheel for the front that is much more f-body friendly. They make one for the rear it would seam they could do the same for the front. Basically the same wheel they have for the rear but factory width so it will fit over the stock calibers.
I will call them today and see if they are interested in modifying a pair of their fbody rear wheels to 8 or 6 inches wide. I bet it will be too big of an ordel.
I guess if I send this brake kit back I can use that money to buy a pair of front wheels and a 10" wide pair for the rear for the street and a 12" wide pair for the rear for the slicks.
This sucks, I really like the look of this rim.

I don't see why not unless they just don't want to do it.
I don't know if you want to spend that kind of money but you could buy the 15x10 f-body specific rear and get it cut down to 15x6, 7, or 8. I have seen rims cut down by some aftermarket companies. I actually saw a 17x4 chrome ZR1.

They dont offer a service to narrow the wheel for liebility reasons.
So I guess I ether need to change all the rims to something else or run a 15" skinny with this brake kit or send it the brake kit back and run 17's up front. Or buy the a set for the rear and send them off to someone else and have them narrawed.
I am leaning toward just putting a set of 17's up front and sending the brake kit back.
