17×9 APEX SM-10RS

Fitment Guide: 1st Gen FR-S/86/BRZ (+35) A mild to healthy amount of negative camber is encouraged. 2nd Gen GR86/BRZ (+48) These wheels require 5mm front spacers and extended wheel studs for strut clearance on OEM Gen 2 suspension. If additional negative camber has been dialed in at the knuckle, a larger spacer may be required. With aftermarket coilovers a 10mm-15mm front spacer and extended wheel studs are recommended to bring wheels flush to fender. Depending on tire size/model and how negative camber is achieved, shaving the inner lip on the rear quarter panel may be needed. Increased negative camber may be/typically required for wider compounds or lowered vehicles. S2000 (+61) 70.1mm to 64.1mm center ring needed for rear. Designed to clear the front upper control arms at full lock under load. Typically a direct fit, but a mild increase in negative camber is encouraged if you plan to run a track/race compound that runs wide. Click here for brake clearance information. SM-10RS Features 10K Tons of Pressure Our new forgings weigh as much as 120 pounds before machining. To form such a thick blank we require special equipment capable of 10,000 metric tons of pressure. This extreme pressure increases the strength of the aluminum by eliminating porosity and improving the grain structure. True Motorsport Blanks Many 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 to give us total control over the final product. I-Beam Spokes One of the most noticeable features of the SM-10RS 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. A Stronger Lightweight Wheel Our 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.² What’s the point of a lightweight wheel if it’s fragile? Weight Optimized We conducted extensive Finite Element Analysis (FEA) to reinforce high-stress areas and to remove material where it didn’t improve strength. The result is a wheel that is exceptionally light without the strength compromises found on typical lightweight wheels. Big Brake Clearance From day one, APEX has been on a mission to build wheels that clear big brakes. Our new forged wheels are the product of everything we’ve developed over the past 10+ years, including an innovative high-clearance barrel design and vehicle-specific spoke profiles. Independently Tested We don’t rely solely on computer simulations or unverifiable in-house testing. 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. Tougher Inner Lip Introducing the Sprint™ spec inner lip, with a unique channel profile that makes it even stronger than our previous designs. So even though our Sprint™ wheels are pounds lighter than comparable flow formed wheels, the inner lip is stronger. Deeper Concavity Our new forgings were redesigned to create extra deep, concave spoke profiles. Their new shape allows us to make any profile, from flat to deep and everything in between. Each one is optimized for a specific application using 3D laser scans of factory and aftermarket brake kits. Pointless Knurled Bead Whether 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. Laser-Engraved Specs As track enthusiasts ourselves, we know how frustrating it is to try to locate and decipher wheel specs that have been hastily hammered into the rim or become unreadable over time. With our new Sprint™ wheels, we chose to invest a little extra and laser-engrave the specs on the barrel, in plain sight, making them easy to find and read.
