Technical Wheel bolt lenght

[jte]

Hi, I bought 3mm Wheel Spacers for my Punto mk2 with alloy rims.
Do I need longer wheel bolts or is standard bolt lenght enough?

They'll almost certainly be too short. Ideally you want 1 1/2 threads through the back of the hub, no more.

You need to measure -- no way round it.

Hope you didn't buy universal spacers...........
