This system uses Wilwood 12.72" diameter and 1.25" wide rotors. Due to the width of the rotor and the size of the caliper this setup will only fit a rear 8" or 9" wheel. I have yet to determine what width spacer would be required to fit the stock front 16x7 or 16x8 wheels. I suspect that if a 0.81" wide rotor is used, they may be able to fit with little or no spacers. I will check into this later.
The part numbers for the rotors, calipers and hats are:
Rotor: 160-2540 and 160-2541
Both of these fit without any necessary modifications to the wheel hubs or the rotor hats. A number of the rotor hats Wilwood offers do not have a large enough centering hole so to find a hat with not only the right offset, but a centering hole that is perfect within 0.010" was to me the holy grail of brake parts. I did, however, modify my wheel hub to use longer press-in wheel studs and drilled and tapped the hubs for rotor retention bolts, but both of these modifications are not 100% necessary.
Eventually I will post up the prints for the mounting brackets, but that will have to wait until I make my bracket for the other side of the car as I forgot to measure a few components before mounting everything up. So for now, enjoy the pictures.
Bigger pads... It's safe to say this is all overkill for regular street tires.
Because these are two piece rotors, safety wire is absolutely mandatory for the retaining hardware. DO NOT forget this!
Drilled and tapped wheel hub for the rotor retention bolts.
The bracket is pretty simple. It is made from 3/8" steel plate and uses two spacers that are 0.44" thick. Each spacer has a flat ground into it for clearance with the strut housing. I ultimately chose to weld these spacers to the mounting plate as I wanted to ensure that the shear point for the bolt was as close to the caliper mounts as possible.
Because of the extreme width of the rotor and caliper, the caliper actually has to be mounted behind the factory location for everything to clear the wheel without a spacer. If the caliper and rotor was moved any closer towards the center of the car (if you were to try to make it clear 16x7 wheels), the rotor will begin to interfere with the lower ball joint of the strut.
Most of the hardware has to be shortened to fit flush with the mount as the rotor to mount clearance is only about 0.125".
Included with the D2 struts was a set of what appeared to be brake line holders. They didn't seem to fit anywhere in particular, but with a hole in the proper place and mount of the holder cut off, it works almost identically to the factory hardware.
Because race car.
And so, onto the prints! Now I will make it clear that these are for open distribution and not to be used for profit! Or at least if you do, help a pal out.
