🏁 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 — 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 — 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.

🚨 Industry First for the 4C: Suspension Just Got Smart 🚨

Alfa9 was the first to bring the INTRAX 1K2 system to Alfa Romeo 4C owners looking for the ultimate setup — 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.

🎛️ EMC — adjust your rebound/compression damping on the fly, from the driver's seat, no tools required
🔼 EHC — 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 — 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.

If you've ever wished you could dial in your rebound & compression settings without crawling under your Alfa Romeo 4C between sessions, this is exactly what you've been waiting for.
