Genuine Right Sill Extension - Ready to Paint - Renault Clio 4 RS

The essential component for your Clio 4 RS structural integrity

Driving with a missing, cracked, or poorly secured sill extension exposes your lower fender structure to road debris and instantly degrades your chassis' aerodynamic flow. On a Clio 4 RS or a Clio Cup, every bodywork detail matters: the absence of this genuine part creates a visual break that significantly devalues your sports vehicle.

A genuine Renault part ready for professional painting

Why risk the approximate fitment of an aftermarket part? This right-hand sill extension is an authentic Renault part. It guarantees a flush fit without modification, strictly following factory mounting points.

Please note: This product is delivered in a raw finish. To achieve a professional result consistent with the original look, an application of primer and the manufacturer's specific paint code is required. This ensures a perfect shade match with the rest of your bodywork, unlike pre-colored plastic parts that may age differently.

• Specific Fitment: Right side (Passenger side).
• Extended Compatibility: Clio 4 RS, Cup, and R3T models.
• Finish: Raw, ready to be painted according to your color code.

Frequently Asked Questions

Is the part already painted?

No, this right sill extension is delivered in a raw finish. It must be sent to a body shop to be painted in the exact color of your Clio 4 RS (Sirius Yellow, Frost White, Deep Black, etc.).

Does this part attach to the bottom of the front fender?

Yes, this element specifically bridges the gap between the bottom of the front fender and the start of the side skirt. It is a zone highly exposed to stone chips during spirited driving.

How to ensure a perfect installation?

While installation is accessible, rigorous alignment is necessary to respect the lines of the Clio 4 RS. Our workshops in Cambrai are at your disposal to carry out this service.
