I've got a set of wheels from an old car that I think might look good on my z31 and after looking at some guides online and doing the math I think that they will fit with the use of a pcd adapter (anybody got any experience using these - OK to use for every day use?) and without having to change the tyres...anyone care to do the math and confirm?

 

Current setup:

5 Lug bolt pattern: 5x114.3

15x6.5 +20mm

Tyres: 215/60/15

 

New setup:

5 Lug bolt pattern: 5x120

17x7.5front 8.5 rear +41

Tyres: front- 225/45/17 rear- 220/40/17

 

Going by the guide on ZBUM's site the offset should be alright, particularly with the addition of the pcd adapter...but I have been trying to work this out at 2am so my math may be way offv:o so anybody in the morning fancy a mental arithmetic work out then feel free to have a go...pretty please :D

I have some PCD adapters/20mm spacers for that pattern - sold them to FunkySi last year not realising they were adapters so he returned them.

cool, I could take them off your hands if I get any confirmation of my late night maths! If no responses then I'll try to go over the figures a t more reasonable hour tonight and check that they will fit.
