AST Suspension Uniball Control Arm Bearing Kit for Clio 3 RS

What you lose by keeping the factory rubber bushings on your Renault Clio 3 RS

Under heavy braking or hard cornering on track days, the original factory rubber bushings of your Renault Clio 3 RS flex under load. By refusing to upgrade to a rigid spherical bearing system, you accept a loss in front-end precision, suffer continuous alignment shifts in camber and toe, and allow a vague, numb feeling to take over your steering. Keeping flexible rubber components also means a slower response time during rapid weight transfers and uneven wear on your high-performance tires under intensive track day use.

AST Suspension Engineering: A locked-in, ultra-communicative front end

This kit designed by AST Suspension completely eliminates that weak link. Comprising 4 uniball joints along with their dedicated inserts and spacers, this system replaces the soft rubber bushings to offer a completely solid, direct connection. Unlike other overly complex suspension solutions on the market, this product offers the massive advantage of installing directly onto the factory control arm without any modification. You keep your stock arm castings perfectly intact while completely transforming the dynamic handling of your racing chassis.

Frequently Asked Questions & Technical Alignment Guide

Does this uniball kit cause excessive vibration for daily driving?

By removing the factory rubber, road surface imperfections are filtered less, transferring a raw, direct stream of information straight into the steering wheel. Failing to make the switch to a uniball setup means keeping a muted, soft ride, but it also deprives you of the genuine steering feel that is absolutely vital to exploit the full potential of a Cup chassis.

Does installing these uniball spherical bearings require special tools?

The kit is fully engineered to match the original internal diameter of your factory control arms. Pressing out the old rubber bushings and pressing in the new spherical bearings is done using a standard hydraulic press, with no machining or welding operations needed.

Is a wheel alignment necessary after installing this kit on the Clio?

Absolutely. Because your front end will regain its absolute rigidity and return to its perfect nominal position, failing to perform a proper alignment (toe and camber) would neutralize the kit's effectiveness. We highly recommend fine-tuning your alignment settings immediately after installation.
