Thanks for a reply , I was figuring on 20mm both front and back, as I have the standard rays engineering forged five spokes wheels which I want to keep as they are already staggered. Car is not lowered, sorry should have said it was all standard. I was looking at 114.3 and 66.1 hub centre, which I understood is the right size?
was a little concerned that if the studs are 24mm would I need 25mm spacers or would the stud ends fit in the wheels?
