what i read it said "Last but not least, the Cup chassis now comes with a higher ratio steering rack (7.5% quicker than the standard chassis) which, combined with other specific development work, favours feedback to the driver in conditions of varying grip.
The Clio Renaultsport 200 Cup weighs 1204kg boasting the best power-to-weight ratio in its class at 166hp per tonne.
The Cup chassis and steering setting is standard on the Clio Renaultsport 200 Cup and optional on the Clio Renaultsport 200. Externally it can be identified by anthracite finish to the alloy wheels and red brake callipers."
