i'm definitely considering weight. i'm on stock 203's currently... according to
http://felgenkatalog.auto-treff.com/ , they weigh in at 11.23kg front and 11.93kg rear...
11.23 kg = 24.71 lbs
11.93 kg = 26.25 lbs
pyspeed claims the v701 is "approx. 24 lbs", so we can assume 25lbs is more accurate. i intend to rid myself of the super heavy runflats during this switch, so overall it should be an upgrade where weight is concerned.
i see the 224m is...
11.20 kg = 24.64 lbs = front
11.70 kg = 25.74 lbs = rear
it would certainly be difficult to justify the v701 vs. the 224m. the advan rs is the next step in that direction (as far as looks), but they're over $600/ea.
