SSR Professor SP5 wheels redefine traditional 3-piece modular design around a single core objective: relentless weight reduction. Utilizing a 10-spoke face geometry directly derived from SSR’s Super GT racing program, the SP5 pairs a stepped outer rim configuration with precision-machined weight-reduction dimples and alternating spoke ribbing to maximize rigidity without adding rotating mass. Joined to heat-treated spun aluminum barrels, this wheel offers high structural integrity, exceptional braking clearance, and a sleek, track-focused aesthetic tailored for high-performance coupes, luxury sports sedans, and aggressive street builds.
