stay away from the plastic ones
-
Remove stock calipers and rotors and clean up the hub with a steel bursh.
-
You will need to bend or cut away part of the dust shield (try bending before you cut though!)
-
Install the hub centric rings and the rotors.
-
Mount the calipers (Make sure the bleed nipples are facing up!) and bolt them up
-
Install brake pads and lines.
-
Bleed the system.
Dust shield: don’t cut this! avoid sharp edges and a dangerous situation. the shield can easily be bent backwards with a hammer. if it still rubs the rotor after installation, use a large screwdriver to pry it away from the rotor.

Paint: I hit the caliper with a rotating wire brush drill attachment, then 100 grit sandpaper and brake cleaner. I used orange and black engine paints. I removed the bolts 2 at a time to paint them separately.
Brake fittings: threads match, use new copper washers, I am using a previously installed SS line kit
Wheels: 17-inch+, i have 18-inch
Piston comparison: 1x60mm MK3 piston vs 2x44mm & 2x40mm MB pistons

Hub: STI hubs are about 58mm. Take the rotor to the machine shop and bore the hubs out to 60.2mm. $64 labor
Dust shield: don’t cut this! avoid sharp edges and a dangerous situation. the shield can easily be bent backwards with a hammer. if it still rubs the rotor after installation, use a large screwdriver to pry it away from the rotor.
Paint: I hit the caliper with a rotating wire brush drill attachment, then 100 grit sandpaper and brake cleaner. I used orange engine paint.
Brake fittings: threads do not match. my understanding is that one fitting is flared and the other is inverted flared. They appear to fit at first but I had a leak. I used the stock evo banjo bolts and added a banjo fitting to my brake lines.
Wheels: 17-inch+, i have 18-inch
Piston comparison: 1x38mm MK3 piston vs 2x40mm Evo 8 pistons
Ebrake: no changes or adjustments, works 100%
