[RSPez]

Hi.

Just wondering what the difference is between a cup and non cup rack is, Iv read it is "Quicker" so I'm Guessing it's less turns lock to lock?

197 Cup

Since 2002, Clio Cup versions have been the benchmark by which all high-performance hot hatches were measured.

The Clio 197 cup was based on the hugely popular Clio Renaultsport 197 and featured a 20kg weight saving over the regular version, as well as cup chassis as standard.

The Cup chassis gave the car a lowered ride height of 7mm, stiffer springs (27% front, 30% rear), 10% stiffer dampers, and finally red Brembo 4 piston brake callipers.

200 Cup

The Renaultsport 200 Cup was the most track focussed vehicle of the Clio Renaultsport family.

With cup chassis as standard, it offered a lower ride height (7mm), stiffer springs and dampers and a quicker steering rack (7.5% quicker), which provided performance and cornering ability that was simply mind boggling.

The Clio Renaultsport 200 Cup also featured the best power to weight ratio in its class (166bhp per tonne).
