These A-Arms are the original solution to unwanted 4C rear end geometry changes and were first developed by Alfaworks performance UK to cure this issue. They are a very important upgrade when using 200 treadwear or stickier tires.

They provide crucial alignment improvements to the factory design, and improve both safety and handling.

Under normal loads and with street tires there is plenty of stiffness in the OEM bushings. BUT, as you increase grip of the tire, more load is deflected into the OEM joints and allows the rear wishbone bushings to flex and start rear steering the car. This situation reduces confidence and control of the 4C.

Using these rear wishbones is the best and fastest way to correct this situation. The uprated bushings that are pressed in, will eliminate unwanted flex in the rear suspension and increase precision. They will also make it much easier to control oversteer by making driver inputs more immediate and effective.

This is a track-day specific intended modification. Although once you install these, your car will still be completely “streetable” using the Cross-Axis Uniball bushings engineered to last indefinitely and operate noise-free on the Alfa 4C. The Cross-Axis style bushing is the best solution to give maximum stiffness, anti-vibration and longevity. Sold in pairs, as complete new wishbones to make for a hassle free and fast swap. No special tools needed for installation.

Developed by Alfaworks UK, Alfa9 is the official Alfaworks USA distributor.

These are made using only factory Alfa Romeo 4C rear a-arms, so you are guaranteed a perfect factory fit on any 4C model, and you retain all of the factory safety features built in. You get all the stiffness benefits, without any undo noise or vibrations added, helping you keep your Alfa 4C perfectly streetable.
