Professional Engineering is not Universal

Tragically many aftermarket parts may “look” good, but at the cost of sacrificing quality, weight optimization and ideal geometry.

The Real Cost of “Discount” Parts:

    • Performance limitations
    • Increased wear and tear
    • Likelihood of catastrophic failure
    • Higher overall cost and opportunity loss

If you can’t afford to build it right to start, then how will you afford to build it again?

Driving to Win Since 2009

History – CorteX Racing launched as a U.S. retailer in 2009. As we grew, our R&D facility at Sonoma Raceway in Northern California became well established as the testing grounds to prove and optimize our novel designs.

In 2019 we expanded CorteX East with our retail and install shop in Ohio. Today, CorteX dealers and installers can be found globally.

Unparalleled Quality, Excellent Value

At CorteX we design, build and race what we sell.
