The Clio RSR Project incorporates a targeted and carefully engineered weight‑reduction programme, focused on replacing heavy OEM components with lightweight motorsport‑grade parts, optimising mass distribution and improving dynamic response without compromising usability or cabin quality.

​

​

Key Weight‑Saving Measures

​

• Replacement of OEM front seats with RECARO Pole Position (ABE)

• Removal of rear seats, rear belts and associated hardware

• Lithium battery relocation behind the passenger seat

• Lightweight motorsport washer bag tank

• Removal of OEM sound‑deadening materials in selected areas

• Custom exhaust system (63.5 mm) with reduced mass

• Removal of rear wiper assembly

• Lightweight PVC door cards and rear interior panels

• Replacement of OEM steering wheel and airbag with Sabelt Renault Sport Cup wheel

• Lightweight front subframe (Renault Sport Cup replica)

• Lightweight flywheel (Madeno Racing)

• Reduced‑weight intake system (Renault Sport Cup airbox)

​

Final Result

​

The vehicle achieves a total weight reduction of approximately 130 kg, combined with a significantly improved front‑to‑rear balance thanks to the battery relocation and the removal of rear mass.

 

Final measured weight (1118.5kg with 10L of fuel): 1111 kg
