3piece wheel is heavy. This common sense became the passed one.
The theme of SP5 is "challenge to lightness".
The know-how for design work, technology for strength analysis and balancing work from the experience in motorsports. We utilize all of them in this SP5.
DISK
The disc on the face of the wheel is the same 10 spokes as the wheel supplied by SSR to the Super GT. It has an excellent shape for securing strength balance and rigidity, and is particularly advantageous for weight reduction. The dimple engraved on the spokes is not just an accent, but a design for lightness that follows it for GT.
SPOKE ＆ RIB
A spoke face that has been thoroughly shaped to the limit. The crotch of the spokes is randomly arranged in shapes that increase rigidity (with ribs) and shapes for weight reduction (taper cut of edges). It balances lightness and strength at a high level.
DISK FLANGE
The weight reduction of the wheel is only with reliable strength securing technology. SSR's inner rim is an HTM rim with a unique heat treatment technology that increases hardness. Without this technology, the groundbreaking thinness and tremendous strength of SP5 cannot be realized.
HTM RIM
For 3PIECE wheels, the fastener, which is the tally of the disc and rim, is an important part that affects the rigidity of the wheel. SP5's design is slimmed while maintaining rigidity. In addition, the commitment to lightness and strength extends to the number and placement of piercing bolts.

CENTER PART
The center part is available in all four types (SL, NR, MD, HP) shapes that can be selected according to the specifications of your car. The color of high metal bronze is a new color from this model.
