Simplicity is the reason why the Yokohama Advan Racing GT Premium is beautiful. The 5-spoke design is made from a one piece, form forged A6061-T6 aluminum. The ADVAN Racing GT Premium Version, which began as a 20-inch version of the R35GTR, are now available in 19-inch and 18-inch versions to fit a wider range of cars. The wheels are available in three colors limited to the GT Premium Version. By wheel size, the colors are as follows: Racing Gloss Black (20-inch only), Racing Gold Metallic(20-inch and 18-inch), Racing Titanium Blue (20-inch, 19-inch, and 18-inch). (Color selection is limited in certain sizes.) The ADVAN Racing GT logo letters are 3D-machined on the spokes. The logos as well as the stickers are part of the wheels?E exclusive design, and result in a finish that says ?Epremium?E at first glance. The 20-inch and 18-inch wheel rims are knurled to prevent tire slippage.
