What adapters do I need

[Blue74l]

This is really so hard to answer over the 'net.

If u have a look on the back of the wheels you will see some cast in #'s. One of them will say ET50 or something similar

I cannot remember my back ET but i think it is 40. My fronts are definitely 50's

This is with 16" 6" & 7" boxster wheels

I dont run any spacers, but my car is Australian 1974 L that has disc as standard

I did have to turn a bolt around on the spring plates and cut a bit off the bump stops for the back.
