1300 R rear Mag wheel on a ....

Would a CT on a 1300R rear Mag wheel fit on a 1800 S.
wanting to try the darkside and have a 1300c wheel sitting arround would it fit??

It is a reverse Foots Mod. It can be made to work, but will not fit without changing several of the parts or milling the 1800 Rotor to work on the 1300 wheel and keep the 1800 brakes.

Probably better to get an 1800C wheel and sell the 1300C wheel.

I dont know if will work in reverse but it should , lets say you have done the foots mod with the 1800 caliper on your 1300 and you decide you want to go back to the 1300 wheel, you can put an 1800S rotor on the 1300 wheel and leave the 1800 caliper in place, so long way around what you want to do should work. good luck
