new wheels... but not for the Alfa 4C.

In a rare departure from selling strictly 4C parts, we are offering Marvic's masterfully made line of magnesium race wheels for historic Alfa Romeos. 

These wheels are perfect replicas of those fitted to the GTA and GTAm cars. Faithfully sand cast in time honored traditional methods in order to offer one of the most authentic renditions of the original Campagnolo Magnesium wheels.

To make them usable on the racetrack with modern tires, they are triple redundancy strength tested to ensure there are no cracks. While the old stock vintage Campagnolos are great for show, they should be limited in their racetrack and road use due to the inherent fragility of older magnesium castings.

A variety of widths and offsets are available. Check out the website under "wheels" for more details, or click the image below.
