Look your kit up on Wilwood's website. There should be a drawing stating all the dimensions the brakes take up, Holeshot should be able to supply you with their data as well so you can compare. Thanks. Pretty sure I got the right part number and now have the caliper radius. But I will check the actual radius with the wheel off. I'm kinda partial to the Penta Star version. Yep me too, Like the look of beadlocks, By the end of last season the radials had moved round the rim almost 180 degree, moved quite a lot at first then seemed to bed in but I'm worried about applying more torque. We are only allowed 10" rim in one of the classes we race as well.
