Offset question

[66coupe]

Will a 18x8 rim with a 40mm offset work with eibachs? Also what size tire should I run? Thanks in advance Jason

I don't know about the Eibachs, but they will work without it that's for sure.
In order to keep your speedometer within the factory specs, you would want to go with 255/40/18.
