Picked up the new S550 for the wife.
Mercedes S550 on 22" Vossen CVT Wheels, lowered and will be tuned by EVS Motors via Renntech.
I have a S600 coming in for myself next month. I have a Wald Black Bison kit and ADV.1 Wheels waiting for it.

BTW, I have brand new take off AMG 20" Multi Spoke Wheels and Tires for sale if anyone is interested.
20" AMG Multi Spoke S-Class Wheels For Sale. PM Me.
Which Renntech ECU upgrade are you having installed in your wife's car? What sort of performance bump are you looking at - the RENNtech website doesn't detail the modified performance you can expect...
