I couldn't find the BBS RI -D wheels on the BBS website. Perhaps this wheel has been discontinued.

I do see FI-021 (9.5in) and FI-022 (10.5in) lightweight forged wheels currently offered, approx. $2,100 per wheel.

My question is, has anyone been able to measure or quantify the performance gains of lighter wheels on a 1M? Perhaps there are handling advantages. Are there advantages in accelerating and braking?
