I'm 95% sure these will work, but I want to run it by the forum peeps to see if y'all agree. These are made for Mazda anyway. The kit includes longer studs to replace the stock ones and the 10mm hubcentric spacer.
Those are different - the longer studs are part of the spacer. The one I'm buying is a regular spacer that includes longer studs to replace the stock studs on the hub. I'll be ordering it next week not sure when I'll install it. Probably the week of July 4th.
I guess I could, but that would mean I would need to get 10mm for the front (to keep the offset same front/back) and I'm not going to spend extra to put longer studs on all 4 corners. Besides, I might get H&R springs to replace the Eibachs and I don't want to push the wheels out too far as to rub the rear fender lip.
(rear wheels are sunken in 5mm compared to the front. That's how Mazda designed it.)
