for enkies in the 15x6.5 size the ones to look at are the ES Tarmac (10.7) and the J-Speed III (12.8)... there are many other companies making light weight wheels other than Volk (Rays) and Rota.... Racing Hart, SSR, Buddy Club, RS Watanabe, Advan, Wed's, Mugen... theres a few of the other companies that have rims in that size that are light weight (<12lbs)
