M3-MADMONKEYMOTORSPORTS Race Lite Rear Brake conversion. This allows you to change to a smaller light weight M3 Race Rotor and M3 Race Lite brake hanger. Loose the weight and clean up that bulky HD caliper and heavy OEM rotor.
Included M3 Race Lite Brake hanger, M3 Race Lite Rear 9 inch rotor for OEM HD wheel, Spacer for M3 Race Light hanger 25mm.
You will need a GSXR1300 Brake Caliper for a 99-07 GSXR 1300. If you are installing on a stock HD swing arm you will need to drill a 3/8 hole in the brake hanger on the stock OEM arm. (You can still go back stock later).
If you have an M3 Arm you will not need to drill anything.
