The org 172 cup has different CASTOR angles to the std 172. Did they use this geometry on all 182s or just the cup and cup packed 182s ? (Hubs are different i think).
Does anyone know ?
some reading
The changes between the 172 and the 182 aren't just about power and pretty exhausts, however. The chassis has undergone revisions that are more significant than they first appear. The
front track (distance between wheels) has been increased by 12mm and the rear by 16mm; the wheelbase (between front and rear wheels) has also been stretched by 13mm. All this talk of millimetres may not seem much, but in essence it is pushing the wheels further out to the corners of the car, giving better stability and improved grip.
The suspension hasn't been left out either. Stiffer front springs (up 10 percent), and a
thicker anti-roll bar at the rear (up 2mm to 24mm) grant 12 percent more stiffness overall. The
castor angle of the front wheels has increased from 1.35 to 3 degrees - this helps to keep the wheels more vertical with the road under hard cornering. All these small changes, coupled with a newly designed, 10mm wider tyre co-developed between Renaultsport and Michelin, keep the 182 firmly pressed to the tarmac.
If all these handling and performance mods aren't enough, buyers can choose to have their cars fettled at the factory for an extra £200. This buys you the Cup chassis option which stiffens the suspension more, lowers the ride height by an insignificant 3mm, and strengthens the steering set-up by the use of larger-diameter bearings in the hub carriers. This keeps the front wheels at their desired steering angle when subjected to cornering forces and acceleration changes - so there's more feedback through the steering wheel. You'll be able to recognise a 'Cupped' Clio 182 by the new eight-spoke alloys finished in Anthracite (dark-grey) and fitted with stiffer sidewalled tyres.
