AST Suspension Uniball Control Arm Bearing Kit for Megane 3 RS

What you lose by keeping the original factory rubber bushings on your Megane 3 RS

The famous independent steering axis front suspension (PerfoHub) on the Renault Megane 3 RS is a marvel of precision, but its factory rubber bushings represent its primary weak link. Under severe braking loads or hard cornering forces, these flexible components flex and distort. By refusing to upgrade to a solid bearing setup, you accept continuous alignment shifts in toe and camber, lose the vital road feedback through the steering wheel, and generate premature wear on your performance tires. Failing to install this motorsport uniball kit means allowing handling vagueness to creep into your lines and adding seconds to your lap times during every track day.

The Mechanical Advantage of the AST Suspension Uniball Kit

The solution developed by AST Suspension permanently eradicates all elastic deformation. This comprehensive package integrates 4 high-strength uniball joints paired with custom-tailored inserts and spacers. The massive benefit of this setup is that it requires absolutely no modification or machining to your factory parts. You transform your sports car's handling dynamics while completely preserving the structural integrity of your original control arms.

Frequently Asked Questions & Front End Assembly Tips

Why choose uniball bearings over polyurethane bushings?

Polyurethane bushings still retain a minor amount of elasticity. Solid spherical bearings, however, guarantee an absolutely perfect geometric alignment under load. Failing to make this choice means accepting a compromise on the steering precision of your Cup or Trophy chassis.

Does installing this kit require any modifications to my Megane?

No, this product has been engineered to press directly into the factory control arm bushing housings. Removing the old parts and inserting the new spherical bearings is simply done using a standard workshop hydraulic press.

Should I schedule a wheel alignment after the installation?

Yes. Because your front suspension will regain absolute rigidity and eliminate all operational play, skipping a full geometry alignment would neutralize the benefits of the kit. We highly recommend setting up your alignment specs immediately after installation.
