Yeah thanks, saw this on MB world, I think the 21's look a little to big, I'm sticking with 20's and going to drop the beast proper with a lowering module, I think Rentech makes one and Merc. might not have issues with the warranty if Rentech is used possibly, I am checking into it now, will advise...

P.S. ^^^ what was the exact size of those 21's what was the width of tires,(front & rear) and offset if you know, also how did it ride and perform with the 21's ...
