If I use the discount rotors and get a rebuilt caliper, I can fit it up quite well before it ever goes on a car.

If I use the discount rotors and get a rebuilt caliper, I can fit it up quite well before it ever goes on a car. Tim That must be a really impressive steel wheel. I haven't seen one yet that will clear a caliper that size on a rotor as shallow as those. I strongly suggest you find a SRT Jeep and break out a measuring device. The center hat of the rotor is less than an inch away from the rotor surface. The caliper sticks out nearly three inches from the surface of the rotor. Your wheels are going to smash the caliper before you can get the lug nuts on. There's a good chance it will contact the outer radius of the caliper too. Mission: Impossible.

I cut the centers out of the wheel, recentered them, and welded them in. Its a 17x7.5" wheel with 3.5" of back spacing. The reason I used these if the fact that I can bolt the brackets on the drum spindles and everything clears. Modern brakes for 200.00 in salvage yard parts. Comes with dual piston calipers and 12" rotors.

Now I just need to find calipers in a salvage yard...Then its measure up and make new brackets....for the largest brakes I can fit on a 68 Charger.

I will have less that 700 in the whole project. I have made the setup for 12" rotors with dual piston calipers that bolted up to the drum spindles and hubs. Its the challenge of making something different that I enjoy.

My rotors are 360mm, and with how the 8 piston calipers sit on them...it is does fit under an 18, but not a ton of room to spare. With the extra 20mm in diameter...so 10mm on one "end" so to speak pushing the caliper out further be interesting to see how it goes squeezing into the same sized wheel. (and depending on the shape of the top of the Jeep caliper too )

They are a little thinner than the ones I use, so at least that helps offset the weight with the extra diameter.
