Remember that the grind marks must run cross-ways on the caliper to prevent the formation of stress concentrations. Corksport's RZ kit instructions will have you grind them the other way; and while I haven't heard of any failing - I don't think anyone wants to be the first to have the calipers split while they're driving

Hubcentric spacer, notice the slight machining to get the rotor to fit.

Rotor sits closer than factory, so this area will need to be shaved down.

Hope this helps, Brian!
