It's very difficult to see the offset stamp on the back of the hub.
I can say they fitt really well on a 300zx and perfect on an old datsun I had.
I'd say +22 ish in the rear and +30ish on the front...
Gold bolts are in good nick, rear tyres are full tread depth (265 brand name tyres).
... Perfect for a 5 stud silvia, r31, gts-t etc.
Pistons are sold, pending payment.
