Paul, The alloy ST4s wheels are heavier. I have the exact weights somewhere (search on Shazamm's posts) but I seem to remember that the 5 spoke allys are only a pound or so lighter than the 3 spoke brembos. I'll let you know about the ST4s rear dimensions in a week or so. I was hoping it'd be a drop in (with bearing changes) but I am now having some doubt. The front is easy, new bearings and a machined monster speedo drive, Job done. Rgds, Rob |
