THE ’70S-ONWARDS CORTINAS feel very civilised thanks to double wishbone front suspension along with coil springs all round. Gone is the steering box too, being replaced with rack and pinion. Even the rear live axle has better control with angled radius rods. With all those links though, the only problem’s likely to be wear in the bushes although that’s nothing that a decent set of poly bushes won’t sort out. Generally, the suspension is similar across the Mk3-Mk5 range although most either swap in the whole suspension from the more-refined Mk5, or use a selection of components from one. Lowering is straightforward — springs and dampers are available off the shelf while you’ve got a range of anti-roll bars from 16-22 mm available as standard to tune the suspension according to use and engine weight.
The Mk3-Mk5 range of Cortinas have much more-modern suspension than the earlier versions, and it’s easy to improve.
