Porshe 5 bolt pattern same as Chevy's?
 

I'm not so good at the metric/traditional conversion ratios. Is the five bolt Porshe pattern the same as the traditional Chevy five bolt pattern? I really don't like the prospect of trying to find a set of rims made for Porsche that will have the sizes and offsets I'm looking for. Anybody got some info on this?

No Chevy rims will not fit, Porsche is one of a kind and metric too! 5X130, there are aftermarket companies that have rims available with this bolt pattern. Good luck Darren

Traditional Chevy is 5-4.75", which in metric would be 5-120.65mm (Very close to BMW, which is 5-120mm).

Porsche is 5-130mm. Newer, smaller chevy's use 5-100mm.

Hope this helps.
