Not long ago, changing your older muscle car over to a coil-over suspension meant big bucks and a lot of fabricating. This type of suspension was for race cars and serious street performance cars only. Not for the masses, and not for you. Today, thanks in part to a growing number of events that combine driving and racing — road racing, in particular — there are now a number of kits available that make converting to a coil-over suspension system much more feasible for owners of classic muscle cars.
