so i need to have the disc mounted to the hub before i can really do any measuring. thats not hard, just need to get the discs re-drilled to fit the ae86 hubs.
once i got the disc on then i can measure to the outside of the disc. but how do i know where to mount the calliper so i can get an accurate measurement to the strut.
hope i didnt just ask what you said, im bit confused!
