ingram4868 Posted May 25, 2009 Report Share Posted May 25, 2009 I have a spare OEM rim in the shed and it weighs 27.5 lbs if that helps any. Link to comment Share on other sites More sharing options...
Imatk Posted May 25, 2009 Report Share Posted May 25, 2009 I got this from the SVT forums. "The exact weight of my 20x10" rear Alcoa is 14.6kg = 32.18 lbs. The weight of the GT500 stock rim (18x9,5") is 13.3 Kg = 29.32 lbs." Link to comment Share on other sites More sharing options...

The weight of the GT500 stock rim (18x9,5") is 13.3 Kg = 29.32 lbs." And the tire weight difference as listed on Tire Rack is: Goodyear Eagle F1 Super Car....... 255's - 28lbs. 285's - 30lbs. vs. Pirelli P Zero........... 255's - 25lbs. 275's - 29lbs. Now it would be nice to get an exact weight of the 20x9" Alcoa also. It appears to me that the "myth" of the 20's being so much heavier "rolling mass" at each corner may be just that, a myth......... If you are someone who is concerned about a possible 1.5 or 2.0 lb. extra on each corner, you certainly are not going to be road racing a 3900lb. GT500.

R Well they are heavier and are unsprung weight which adds to that heft. 20s are not for handling... they're for looks, but they DO look awesome If the stock 18s were forged you'd be looking at a much larger gap.
