Alfa Romeo GTV & GTA Suspension

from $2,950.00

New: Inverted Adjusters — Now Standard on Tarmac Kit 1

After years of fitting Intrax suspension to Alfa Romeo GTVs and GTAs, we saw an opportunity to improve on-car adjustability. At Alfa9's request, Intrax repositioned the adjusters to the bottom of the unit — making damping adjustments quick and easy with the suspension fully fitted. No removal necessary. This is what happens when your suspension supplier is a true Alfa fanatic.🏁🇮🇹

The Tarmac Kits

Developed by Alfa9 Supply and built to order by Intrax Racing of Holland — the most proven name in European coilover engineering. We are the sole official Intrax importer for Alfa Romeo in North America, and these kits represent over ten years of real-world development on GTVs and GTAs driven hard on American roads and racetracks worldwide.

Both Tarmac Kit 1 and Kit 2 feature single-knob adjustability of rebound and compression in 40 click steps — delivering the perfect damping ratio across the full range of adjustment. Every kit is built to Alfa9 specifications with your car and intended use in mind.

Tarmac Kit 1 — The definitive street and fast road and track day setup. Now with inverted adjusters for on-car adjustability. The most accessible entry point into a serious Alfa suspension.

Tarmac Kit 2 — For drivers who demand more. Higher specification components for track, hillclimb, and full competition use.
