I had these Volks wheels on my S for almost 50k miles and I love them, they are light weight but much wider than the S 19" stock wheels. Therefore, I still lose about 5 to 8% range with these wheels on my S, but not by much. After I traded in my S for the X75D, I was trying to sell my Volks because I didn't realize they would fit the X with stock 20" tires. I am so glad I didn't let them go because they fit my X and are much lighter than the stock 20"wheels. here are the specs in terms of weight. Stock 20" weight: Front 30.7lb (wheel) 62lb (with tire), Rear 32.4lb (wheel) 64.3 (with tire) Volks 20" weight: Front 23.7lb (wheel) 54.9lb (with tire), Rear 24.3lb (wheel) 55.5 (with tire) Weight of tire only: Front 31.2lb, Rear 31.5bls Weight reduction: Front -7.1lb, Rear -8.8lb I have not get a chance to drive much yet, but the car feels a bit quicker and I expect to gain at least 5% range which would be nice.
