To form such a thick blank we require special equipment capable of 10,000 metric tons of pressure, well above what most other brands use. This extreme pressure increases the strength of the aluminum by eliminating porosity and improving the grain structure.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eTrue Motorsport Blanks\u003c\/strong\u003e\u003cbr\u003e\u003cspan\u003eMany companies use 3rd-party blanks intended for non-motorsport wheels which can severely limit sizes, concavity, spoke design, and critical brake clearance. We designed our very own blank profiles from scratch which gives us total control over the final product, resulting in exceptionally deep spokes and stronger designs.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eI-Beam Spokes\u003c\/strong\u003e\u003cbr\u003e\u003cspan\u003eOne of the most noticeable features of the SM-8RS is its use of side-milling on both sides of each spoke, creating an I-beam effect. Any excess material that doesn't add strength is carved out using a precision CNC ball cutter. Side-milling is often deemed cost-prohibitive by others, but for true performance without compromise we believe it's essential.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eA Stronger Lightweight Wheel\u003c\/strong\u003e\u003cbr\u003e\u003cspan\u003eOur forged Sprint™ wheels are lightweight without the strength compromises found on typical lightweight wheels. First, we carved out as much material as possible, then we purposefully added one pound back to reinforce critical areas, creating a stronger inner lip and a higher load rating.¹ What's the point of a lightweight wheel if it's fragile?\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eLoad Ratings (lbs)\u003c\/strong\u003e\u003cbr\u003e\u003cspan\u003eJWL Load Standard: 1,168\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eTypical Forged Wheels: 1,213\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eAPEX Forged SM-8RS: 1,400\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eWeight Optimized\u003c\/strong\u003e\u003cbr\u003e\u003cspan\u003eWe conducted extensive Finite Element Analysis (FEA) to reinforce high-stress areas and to remove material where it didn't improve strength.

We believe independent testing is critical to protect consumers in this unregulated industry. We chose STL, an independent lab in Ohio, to test our Sprint wheels far above JWL standards, including increases in testing duration, impact drop height, and total load.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eTougher Inner Lip\u003c\/strong\u003e\u003cbr\u003e\u003cspan\u003eIntroducing the Sprint™ spec inner lip, with a unique channel profile that makes it even stronger than our previous designs.

Our new forged SM-8RS is no different and the 9\" and 10\" fitments were designed specifically to clear both the ND's large OEM Bremos and aftermarket BBKs.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003ePaintless Knurled Bead\u003c\/strong\u003e\u003cbr\u003e\u003cspan\u003eWhether it's a day at the track or months of street driving, repeated hard braking and acceleration can make a tire slip along the bead seat and go out of balance, causing vibration. Knurled beads help, but are less effective when painted over. Our forged line features unpainted knurled beads that stay sharp and maximize grip.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eBuilt for Impact Sockets\u003c\/strong\u003e\u003cbr\u003e\u003cspan\u003eTrack wheels need track tools.
