Going 20inch on the w212 amg's does it raise the car?
Also does it handle better with the 19's or 20's?

It raises the car a bit, ride is stiffer as expected. Performance wise 19's are better.

I've been thinking about 20's but haven't made the move as the standard ride comfort isn't amazing coming from a 760li.

So last thing I wanna do is make it worse by adding wheels and drop. Both of which I'm ready to do

Anyone make the upgrade and have any input? Seems for a 20" on the rear, tire size will be 285/25/20 - less sidewall so stiffer ride and pothole alert.

c32_amg

Yup tyre sizes I've been researching are 255/30/20 front and 295/25/20 rear.

Not much cushioning on the sidewall so defo a harder ride and possibly cracked wheels.

I run 245/30/20 Front on 9" wheel and 285/25/20 rear on 10.5" wheel on my E63. I also live near Chicago where the roads aren't that great. The ride is harder on 20s with thinner sidewalls no doubt, but it's really not much worse than the stock set up. I want to go back to 19s and do a fatter tire set up for next summer.

^ Good Info - debating 20's - if they are no worse than stock than shouldn't really be an issue. Is the ride that much worse?

c32_amg

I've noticed a few members say they are going back to 19's after having 20's

Enough said! lol

I was considering 20" when ordering new wheels. Like raudiace4 stated, everything I found indicated better performance with 19". The ride was less of a concern for me since most of the roads here are pretty decent. The clincher was when I couldn't find tires with the correct load rating...given the weight of the wagon, that wasn't something I wanted to take a chance on. I went with 19" HREs with a 10" rear.

Anyone interested in a group buy - not sure if we can get a decent discount.. maybe in an HRE FF01 - Flow Form 19"?

There is definitely a difference in ride quality from 19's to 20's. For all intents and purposes the E63 is a performance vehicle - it was never meant to float around like a Rolls-Royce. From my experience if a customer is unsure about going to 20's due to ride quality then it makes me 100% sure that 20's aren't for them.

Mine has the 20" and I think are really harsh for the PNW. I would loved to have the 19"

If anything I'd go from the 19's that are on my car down to 18's. Might not look as good, but would ride even better than stock I'd think, more sidewall and less chance of the rims getting curb rash. Just a thought.

Good grief. Should have read this thread before dropping $4k on a set of 20" gloss black rims going in next week. I will never track this car so saving tenths on performance isn't a concern for me. But I guess I will find out how ride quality changes, sigh.

Niche Veronas, which they had to paint gloss black, then some Nitto tires. I know jack about wheels and tires so I let the local high-end wheel shop hand-hold me (my E63 is usually the cheapest car in the garage when I swing by, lol).

David, Very cool that your giving "real world" advice here....
