Hey there,

I'm looking for some 21inch wheels for my s320cdi (with amg bodystyling) and really like the kahn rsx alloys. I'm being offered a good set off an audi a8, but I don't know if they will fit a w221 without the need for spacers and what not?

Also, for those who have a w221, what's the jump in comfort like from 19inch wheels to 21?

Thanks

the center hub on an A8 is 57.1 millimeters and the Mercedes is 66.56 millimeters so, if the wheel is hubcentric they will not fit without a visist to a machine shop. The Audi also uses an offset which is lower than the w221 chassis uses. The Audi is also a quattro so, all 4 wheels are the same szie and your car would look much better with a wider rear wheel and tire (commomly called a staggered wheel and tire)

in my opinion not really a good fit

Thanks for that Luke. I'm a real novice when it comes to alloy fitment and everything. I've come across the same alloys again; this time in fitment of 10.5 J21 H2 ET 35 (rears.) The fronts are 9.5. Should these fit?

Also is the fitment the same for the w220 and w221?

Thanks
