18" wheel weights and size.
Also, I want to minimize unsprung weight if possible. Where can I find information on the weight of stock wheels versus that of aftermarket or other AMG wheels.
Agree Wheelexperts.com?
18" AMG monoblock 18x8 ET31 27.5lb (cast)
18" AMG monoblock 18x9 ET35 28.6lb
18" OZ Superleggera 18x8 18lb
18" OZ Superleggera 18x9 19lb
18" Renntech 18x8.5 20.8lb (cold forged)
18" Renntech 18x9.5 21.2lb
18" Fikse FM5 18x8.5 22lb (forged center)
18" Fikse FM5 18x9.5 23lb
18" SSR Intergral 18x8 19lb (semi-solid forged)
18" SSR Intergral 18x9 20lb
I do not put in Brabus or Lorinser weight since your aim is to lower unsprung weight. Brabus and Lorinser would be heavier than the AMG wheels (low 30s lb)
Tire size 245/40-18:
Michelin Pilot Sport 25.0lb
Bridgestone S-03 27.5lb
Toyo T1-S 24.0
Dunlop SP9000 26.5
Yokohama AVS db 25.1
Yokohama AVS Sport 25.3
Tire size 275/35-18:
Michelin Pilot Sport 27.0lb
Bridgestone S-03 29.0lb
Toyo T1-S 25.6
Dunlop SP9000 27.1
Yokohama AVS db 27.3
Yokohama AVS Sport 28.0
You can see that S03s are relatively heavy tires
Hope this info help
Like JustinTRW I'm going to upgrade my C32 wheels to 18's. Does anyone have weight data on the Brabus Monoblock VI 2-piece. I'm considering:
8.5 x 18 Front
9.5 x 18 Rear
Will the new wheels influence the performance of my vehicle? If so, how? Thanks is advance guys!

Tomaso.
