The special aspects of the new casting 1-piece RG-D2 models include the step-rim form. Three types of concave spokes are standard designs for 18x7.5J/8.0J/8.5J, while 18x8.5J/9.0J/9.5J are the GTR design, and 9.5J/10.0J/10.5J/11.0J are the Super GTR design, each with as great a concave design as is possible with casting wheels.
ADVAN Racing FLOW FORMING JAPAN MADE logos are printed on the step of the rims by a thermal-transfer method, so everyone can tell these are ADVAN Racing wheels. The spokes are side cut on both sides, without joins, using the “advanced side cut” process. These 18-inch wheels have the racing rim profile necessary for 18-inch wheels to accommodate brake systems with rotor sizes of up to 400mm diameter.
RG-D2 are available in the following colors: Machining & Racing Hyper Black, Semi Gloss Black, and Machining & Black Gun Metallic which was newly developed.
The six spokes that are a tradition of the RG design have side cut machining in accordance with the latest ADVAN Racing technology trend, and advanced side cut swoops between two spokes with no join.
