@FJ ,
Volks wheels are VERY expensive , last time i checked a set of Volk CE28N 17" costs $2000 above for brand new that is like 2000@86 = Rs 172000, not including duty :(,
Other option is Volk CE28n knokoffs they are exact copy of Volk and are know as Rota DPT , and a complete set will run you about $600-700 .
And please yaar , dont go for the KHANDAANI rims , RX-7 deserves good tuner looks with slick JDM style wheels.
Fahd.
