Both the front and rear suspension have been modified to suit the
demands of competition and to enable the accurate and easy adjustment
of camber, wheel alignment and ride height.
The front suspension is of the independent McPherson strut type with
aluminium wishbones and the rear suspension is multi-link with 'LSA –
System' (light, stable, agile).
• McPherson strut suspension
• Adjustable main spring
• Adjustable anti-roll bar
• Two way adjustable dampers
The front coil spring has a three-step adjustment range, the
corresponding spring rates are listed in the table below:
Colour
blue lilac 997.343.531.9B
golden yellow 997.343.531.9D

The spring is twisted into or out of the spring saddle in the individual
positions to achieve each spring rate. The maximum spring stiffness is
achieved by screwing the spring completely into the spring saddle.
