The 17's are genuine MB wheels and at least 5lbs lighter.. maybe even more than the after market 18's .Happen to know the mass difference between the 18 and 17 wheel?
Perhaps something like 48lbs vs 43lbs?
I see ... -5lb sounds about right (?)The 17's are genuine MB wheels and at least 5lbs lighter.. maybe even more than the after market 18's .
I was also running a 235 on the 18's ,225 on 17's
So a bit more rubber to factor in also!
Handling is alot more snappier,and you are correct,the less unsprung weight the better as far as Im concerned..it's certainly an improvement, I used to have 18 inch OZ superturismo gt's on my audi TT and they where 7 lbs lighter than the standard wheel,that car was awesome in the twisty'sI see ... -5lb sounds about right (?)
Just figured less unsprung weight (say -10%) at each corner so handling would be snappier
I do know going from 48lb (oem 18s) to 41lb (forged 18s) does indeed make a difference
You just sealed my decision to go with 17" rims as part of brake upgrade to SLK350. I was eyeing 18" rims, but I was concerned that I'd trade ride quality for look. Thank you!
