Hi, I decided to get new wheels for summer. I have a 2009 E92 335xi. This is my daily driver, but will have a few track days in its future. I'd like to stick with the stock tire size of 225/45-17 all around. Thinking of getting Pirelli P Zero RFT, Max Performance Summer, 91W. After a bit of research, I've narrowed the wheel search to 1) BBS SR, 17x8, 30 offset, 24 lbs, pressure cast, made in Germany; or 2) TSW Nurburgring, 17x8, 35 offset, 18 lbs, rotary forged, made in ?. I'm not into 'bling', I just want a good quality, strong wheel that's not more than $300 and still acceptable for occasional track use. Which of these is better quality? Does the 6-lb weight difference mean that much? Are there better ones I'm missing? I appreciate any opinions. Thanks.
