Flow Forming? What鈥檚 that? Well ask Fifteen52 and they鈥檒l tell you that flow forming is revolutionizing wheel craftsmanship, setting itself apart from traditional methods like low-pressure and gravity casting. The process starts with a cast wheel, which is then subjected to heat and pressure on its inner barrel while being spun. This technique stretches and compresses the aluminum increasing tensile strength and shock resistance all while reducing weight.
The Apex RSR is Fifteen52鈥檚 newest flow formed, lightweight mesh wheel engineered for ultimate performance. Originally launched as a forged wheel, it is now available in durable flow formed construction. Split 7-spokes are scalloped for reduced weight and maximum rigidity, the Fifteen52 Apex RSR delivers top-tier strength and speed. Two face profiles offer maximum brake caliper clearance and lip size, while variable depth lug bowls reduce weight. A reinforced outer lip and oversized lug pockets ensure track-ready utility.
Available in Matte Titanium, Frosted Graphite, Rally White, Radiant Silver and Asphalt Black colors, square and staggered fitments, light weight, and available in 18", the Apex RSR is ready to hit the road and track.
