I have a set of Kinesis K20 ultra-lightweight 3-piece wheels. These wheels are some of the best quality, and most lightweight wheels on the market. The Sizes are 18x9.5 fronts and 18x11 rears. The bolt pattern is 5 on 4.5'', the same as 5 on 113.4mm. I had billet aluminum adapters made to fit my Lighting from 5x4.5'' to 5x135mm. These adapters make the wheel backspacing the same as a factory Lighting wheel, so they fit the same as your stock wheels. The adapters are included with the wheels!The lips are polished and the centers have been powdercoated gloss black. The rear wheels come with mounted set of BFG G-Force TA 335/30/18 tires with 75% thread. The rims are in very nice shape with almost no marks or curb rash. These wheels will cost you $4000 new, not to mention the rear tires that are worth $300 each new. I'm ready to sell them and start on a new project. Looking for $1600 for the 4 wheels and 2 tires.
