Hmmm...
182 Press Release:
"The new Clio Renaultsport 182 also offers the options of a Cup chassis upgrade and a Cup spoiler pack. The Cup chassis option, costing £200, adds Michelin Exalto 2 tyres with stiffer sidewalls, a 3mm lower ride height, stiffer springs and dampers and new steering geometry plus Anthracite colour wheels.
The front track is 20mm wider and the rear track is 10mm wider improving the cars’ stance on the road and improving the road holding. With higher spring rates at the front, the Cup suspension is firmer and provides more responsive behaviour. These modifications are complemented by the adoption of tyres of an extra-stiff structure. Steering response is thus more direct, with a more incisive front suspension. Also enhancing driving efficiency are the flexible lower leaf of the front bumper, and the larger rear hatch-mounted spoiler, providing greater downforce and aerodynamic refinement."
Compared to the Cup:
Suspension lowered by 3mm
Higher front spring rates
Firmer ride
Front track 20mm wider
Rear track 10mm wider
Front castor increased by 3
Tyres have stiffer sidewalls
Enlarged rear hatch spoiler
(Renaults own words)
Sounds pretty similar to me...
Ok, so some things have changed, such as the wheelsbase & front hubs, but it aint "massively" different to an original Cup that was my point.
