As part of our forged Sprint™ line, the VS-5RS was built to be extremely light while still offering a meaningful strength increase over our flow formed wheels. Engineered for drivers looking to shed as much weight as possible to improve lap times.
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.
10K tons of pressure
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 which gives us total control over the final product, resulting in exceptionally deep spokes and stronger designs.
True motorsport blanks
“Forged” doesn’t mean strong. Many forged wheels focus on weight reduction so much that they end up with the same load rating as cast wheels. Think all forged wheels are stronger than cast or flow formed? Think again! We added up to 1,000 pounds of extra load capacity per vehicle compared to our flow formed line MORE STRENGTH
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.²
Weight optimized
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.
Independently tested
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.

The flow formed EC-7 featured our first barrel design with Brembo 380mm clearance behind 18” wheels. That clearance is carried forward to the new Forged version. Typical blank forgings can have poor brake clearance profiles. By developing our own new profiles and new dies, our wheels can clear Brembo 380mm kits behind our 18” wheels and 400mm carbon ceramics behind our 19’s. IMPROVED BRAKE CLEARANCE
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.
