ALT10 Forged Wheels — C6 Corvette
The ALT10 is the perfect addition to your C6 Corvette. Its split-spoke design brings a modern, sophisticated look to the car while the forged construction delivers the strength and weight savings a cast or flow-formed wheel can't match. Every profile is drawn for maximum concavity, and clearance has been engineered for the majority of big brake kits on the market. Price is for a complete set of four wheels.

- Valve stems are not included — your installer will need to supply them.
- Stock TPMS sensors are transferable; have them moved over during mounting.

We recommend working with an installer familiar with staggered forged wheel setups and low-profile performance tires.
Disclaimer
Made to Order
Each set is forged and finished to order in the size and finish selected at checkout. Because production begins once the order is placed, please confirm your sizing, offset, and finish carefully before purchasing. Build times are current estimates and may vary slightly with production volume.
Finish & Fitment
Finish appearance may vary slightly from photographs due to lighting, screen calibration, and the nature of the finishing process. Brushed finishes in particular will show natural variation in grain. Vehicle ride height, camber, tire choice, and aftermarket brake components all affect final clearance, and buyers are responsible for confirming their setup will accommodate this fitment.
Feedback & Legal
We are a small, family-owned business. If any customer or competitor attempts to misuse feedback systems — such as threatening negative feedback to obtain a refund, or leaving false or malicious reviews — we will pursue legal action to the fullest extent permitted by law. We work hard to build our reputation and believe in fairness and accountability for all parties.
