Overflange 15-spoke design
- This is the fourth generation of the RC series, an acronym for Rally Competition. The 15-inch size for gravel is the debut.
- The RCⅢ 10-spoke design has been replaced by a 15-spoke design for the RC-4, which is more reminiscent of a WRC machine.
- Cast 1-piece wheel. The RC-4 is lighter in weight than the RCIII while ensuring sufficient drivability on rough roads.
- Designed for use with 15-inch calipers such as Endless brand for competition.
- Decals of the new RC-4 logo, which is based on the TC-4 and RG-4 logo design, are heat-transfer printed in two places on the rim flange.
- The RC-4 18-inch, which was preceded by a competition-specific model with PCD136 for the Yaris Rally2 Tarmac, will finally be available in the standard PCD114.3 size.
- The exact same mold as the Yaris Rally2 Tarmac model is used, and the tires are knurled to prevent rim misalignment, for trouble-free performance even in competition specifications.
- Three colors—Rally Gold and Rally Gun Metallic, in addition to Rally White for the Yaris Rally2, are also available. ADVAN Racing RC-4 rim decals are also printed in three locations.
