Hey I got a silver 2000 w210 e55 with stock wheels on it right now. I saw a set of wheels I think I'd like on the car but I can't figure out if they will work or not. So many different things I've read about et of wheels and etc contradict each other. So I was wondering if these would fit.

Staggered 18' Porsche Wheels (Came off of a Porsche 911)

18x8.5 (et-40) & 18x11 (et-25)
Porsche fit 996, 997 & 991 Turbo & C4S application
They are the techart formula gt
