THE SP20 uses the familiar MacPherson strut front suspension design and twin trapezoidal link arrangement at the rear. The latest 323 upgrade brought with it improvements to the suspension mounting system including an additional front transverse member and a stiffer front crossmember. Improvements to the rear cross lateral link and central mount aimed to further enhance vehicle dynamics. The SR2 suspension incorporates additional rear performance rods and heavier duty front and rear stabiliser bars (22mm diameter front, 15mm rear).
