[QUOTE="Cixo-cixo, post: 737437, member: 46832"] Did some digging around about how much performance gains one will get if one buys lighter rims? Answer is very very little performance gain.... [B]-0.111 secs acceleration and 1.8 km speed gain by shedding 37.2 kgs ( about 9.2 kgs off each tire+rims)[/B] track tested results [URL="http://www.hotrod.com/cars/project-vehicles/116-9905-light-vs-heavy-wheels-comparison/"]HERE-0[/URL] Other dyno tested sites [URL="http://www.audizine.com/forum/showthread.php/467909-Dyno-Runs-The-effects-of-wheel-tire-weights-on-wheel-horsepower"]HERE-1[/URL] and [URL="http://www.s1000rrforum.com/forum/s1000rr-hp4-tech-performance-chat/39681-effect-lightweight-wheels-dyno-numbers.html"]HERE-2[/URL] also supported the track test above ( i think ) Any real experience or data on your bimmers after you change your rims to lighter set of tires+rims? So other sites wrote that if you want to get rims, it should be either for LOOKS or PERFORMANCE. Since results/numbers show insignificant ( relative to real world driving conditions ) - this leaves only LOOKS into the equation. Hrmm....What do you guys think? Cixo [/QUOTE]
