"My car is now getting on for a quarter of decade and in that time has probably never had any of the suspension bushes renewed. We approached local firm Poly Performance for some advice. Proprietor Andre Zimmerman was keen to help out. Within two days his company had created a bespoke set of polyurethane suspension bushes (34 in all) for all the suspension arms and links. Remember that an MX-5 is suspended by double wishbones at each corner."
