๐Ÿ‡ฎ๐Ÿ‡น NTM Forged Wheels โ€” Made in Italy. Built for the 4C.

We just dialed in this Rosso Alfa 4C with a set of custom-forged lightweight NTM wheels, hand built in Italy.

As the exclusive USA partner for NTM, we were the first to bring this Quadrifoglio-inspired design to the 4C โ€” and the fit shows. Razor-sharp edge transitions, deep rear concavity, lines that flow with the car like they were always meant to be there.

Beyond the look, the drop in unsprung weight brings a noticeable sharpness to the 4C's unassisted steering. You feel it immediately.

Custom offsets available to dial in your exact fitment. Let's talk.

Tarmac Kit 1 just got better.

After years of Intrax RSA & 1K2 installations on Alfa Romeos, we knew exactly what needed improving. Inverted adjusters โ€” repositioned to the bottom of the unit so you can dial in your damping with the suspension fully fitted. No removal. No hassle. Just turn and go.

This is an Alfa9 development. Exclusively available in North America through us.

๐Ÿ Ten years of Alfa 4C-specific development. Custom-built for your car, your driving, your track.

The Intrax motorsport coilover kit for the Alfa Romeo 4C is built to order โ€” spec'd to your driver weight, vehicle weight, and aero package. We go further: tire compound, horsepower, and your car's specific performance modifications all factor into the final valving and spring rates.

Mounting points are upgraded to ultra-precise spherical bearings for maximum chassis feedback through the 4C's carbon fiber monocoque tub, giving ultimate accuracy. Beyond that, our Intrax 4C kits offer a range of upgrade configurations to further tailor your setup: 2-way and 4-way adjustability, optional Black Titan anti-friction coating, and ARC bump control reservoir upgrades. A truly customizable system, inside and out.

Backed by a decade of dedicated Alfa 4C development and a global customer database across motorsport and street applications โ€” real-world data applied to your exact 4C setup.

Alfa9 Supply was instrumental in bringing Intrax to the US market for Alfa Romeo owners, and remains the exclusive US distributor for Intrax on the Alfa Romeo 4C.

๐Ÿšจ Industry First for the 4C: Suspension Just Got Smart ๐Ÿšจ

Alfa9 was the first to bring the INTRAX 1K2 system to Alfa Romeo 4C owners looking for the ultimate setup โ€” with the XL inverted rear MacPherson design, ARC bump control, Black Titan anti-friction coating = Proven hardware, trusted by 4C owners who take their setup seriously.

Now, working with our partners at Intrax Suspension Technology in Holland, we're bringing something that's never existed on this platform before: in-cabin electronic control, combined with ride height control.

๐ŸŽ›๏ธ EMC โ€” adjust your rebound/compression damping on the fly, from the driver's seat, no tools required
๐Ÿ”ผ EHC โ€” front ride height lift control, so steep driveways and approach angles stop being a threat to your splitter and low nose

This is the first time the 1K2 has been paired with this combination on a 4C โ€” genuinely new territory for the platform.

It's in active production right now, and here's a sneak peek straight from the Intrax workbench as the electronics come together.
