Go with Wedsport TCo5N in 18... Aggressive offsets I believe off the top of my head 18x9.5 and 18x10.5 +10 or +12 and come in various colors and ONLY WEIGH 17 pounds!

Like 2000 bucks for the set, made in Japan. Weds do a cast/forge process so the wheels come out super light and super strong... Just a different thought then then typical track wheels.
Also could look at Enkei RPF1 18x9.5 and 18x10.5 (+15) those only weigh around 18-19 pounds and are super cheap!
