Average Torsional Stiffness

During development we did not stop at OEM targets. We exceeded them significantly.

Axle-by-Axle Technical Analysis

The result is sharper steering, outstanding stability even at high speed, and a purer, more engaging driving feel.

Front (20x10)

Camber Stiffness +0%
Torsional Stiffness +0%

Rear (21x13)

The result is sharper steering, greater high-speed cornering stability, and a more communicative feel for the driver.

F1 Method, 9RS Application

Controlled Production, Wheel by Wheel

We produce 9RS with rigorous processes, constant checks, and extremely high quality standards. Every wheel has a unique serial number and a dedicated technical sheet.

Different material. Same method.

9RS is made of forged aluminum (AL6061-T6), while Formula 1 wheels are made of magnesium (AZ80). The material changes. The method does not.

The 9RS project is developed by the same engineering team responsible for Fondmetal Formula 1 programs.

Not mass production. Controlled production, wheel by wheel.

9RS Track-Day Engineering

Engineered for Extreme Track Loads

Traditional aftermarket standards are developed for general road use. 9RS was engineered with structural margins dedicated to track-days and high-grip tires.

Reducing unsprung mass means:

More effective braking
More responsive acceleration
Greater turn-in precision

We follow the same principle used in Formula 1 programs: reduce inertia and keep an extremely solid structure, turning every driver input into real performance.

Formula 1 Legacy

Historic F1 Logo on the 9RS Centerlock

The 9RS centerlock features our historic F1 logo used in GR01 and GR02 programs. It is an identity symbol also used on drivers helmets and suits during Fondmetal Formula 1 campaigns.
