Last month, HPP brought you a selection of bolt-on suspension kits for your vintage GTO, LeMans, Tempest, or T-37. There were so many aftermarket offerings available that we couldn't fit all the manufacturers into one issue. So here we are again with four more companies that say they can help you turn your classic Pontiac A-body into a corner-carving conqueror of the open road, the road course, or the autocross.
Upgrading the suspension on your classic A-body is an easy way to improve its handling, give you greater performance, and gain a level of safety only modern components can offer. So as not to leave you in suspense any longer, let's get right to the kits.
