Built to be driven
Upgrade to the tactile, mechanical feel and clicks of a gated manual for your fast shifting dual clutch supercar.
USA In-house manufacturing
Made in USA.
Everything we produce—from the Quickshift to the Carbon Fiber Aero and forged wheels—is created under one roof in the United States for complete control over design, development, quality, and finish.
Quickshift Conversion
Driver interface
Switch between
automatic to gated manual
to paddle shifters instantly.
Quickshift pairs a physical gated shifter with an electronic interface that communicates gear-change commands to the vehicle's existing transmission. The driver moves the shifter through its gates by hand, while the dual-clutch transmission executes the shifts and manages clutch operation.
Quickshift introduces the philosophy behind Limitless Engineering: create products that make exceptional cars more personal, engaging, and rewarding to drive.
Now available with clutch or without
With clutch
You control the clutch for a more traditional manual experience.
Without clutch
For ultra-fast shifts, the computer controls the clutch while you shift the gate.
Short, direct throw
Precision rev matching
Tactile engagement

Forged Wheels
Aluminum + magnesium
Two materials.
One standard.
Our forged wheels are engineered for any vehicle — with a focus on high-end cars such as Porsche, Ferrari, and Lamborghini. Choose any RF model, then configure the complete wheel face and full wheel barrel independently. We engineer the diameter, width, offset, and brake clearance around your car. Forged aluminum and magnesium, developed and manufactured in house in the USA.
Carbon Fiber Aero
Hand-built in houseCarbon Fiber
Aero.
Fully carbon. Hand-built in house.
Carbon Fiber Aero is custom-engineered for each vehicle, then sculpted, laid up, and hand-finished in-house in the USA.
Bespoke commission
Anything you can imagine.
Built once.
Commission your own build for absolutely anything. Any material, any car, any design—if you can describe it, we will work with you to engineer and hand-build a one-of-one piece for your vehicle. Carbon fiber, fiberglass, 3D-printed development, forged metal: the process bends to your vision, never the other way around.
