My understanding is that the usual 25mm Eibach spacers for a 350Z are S90-4-25-019...
Number of Holes: 5
Bolt Hole Circle Ø [mm]: 114,3
Thread Size: M12x1,25
Centering Diameter [mm]: 66
Track widening per axle [mm]: 50
Thickness [mm]: 25
Rim Offset [mm]: 15
I've seen it stated before that the same spacers will fit a 370Z, but checking compatibility, it recommends S90-4-25-050...
Number of Holes: 5
Bolt Hole Circle Ø [mm]: 114,3
Thread Size: M12x1,25
Centering Diameter [mm]: 66
Track widening per axle [mm]: 50
Thickness [mm]: 25
Rim Offset [mm]: -15
So the only difference is "rim offset", but I can't work out what that refers to or whether it is important...
And while I'm asking questions, can anyone confirm that S90-4-30-036 will fit? Most compatibility checks say they don't, but i'm not sure if that's just because they are pushing the legal limits of the tyre poking out.
