The 18" 513M wheels per BMW weigh 19.1 / 21.4
The 19" 437M wheels per BMW weigh 21.9 / 22.7
Current weights for BBS RI-D
front 19 x 9 22 5x120 72.5 bore = 7.4 kg (16.3 lbs.)
rear 19 x 10 25 5x120 72.5 bore = 7.7 kg (16.98 lbs)
Unbelievable! > 2.5 kgs (5.6 lbs) lighter per wheel !!! Over 22 lbs less unsprung weight in total.
$ = 2.5k per wheel...
