Focus RS Buying Guide: Rolling chassis

Mounting the wheels and brakes at the front to the chassis are stronger lower A-arms with a hydro bush and a MacPherson strut with 25mm shorter spring to lower the RS's ride height next to a standard Focus hatch's. Sachs dampers are used and the anti-roll bar is 18mm thick, down from the standard 2.0-litre Focus' 21mm item to give the RS better traction.
For the rear suspension, Ford stuck with the Control Blade multi-link system, firmer settings, Sachs dampers, anti-roll bar and redesigned spindles to cope with the wider track. As with the front suspension, some negative camber was also designed into the rear suspension, while stronger wheel bearings were fitted to cope with cornering forces of up to 0.94g generated by the Focus RS.
The final change to the rolling chassis of the Focus RS over a standard model was the quicker steering rack. Ford used stiffer mounting bushes to help give more steering feel and the rack itself has 2.9 turns from lock-to-lock.
