In the end, the objective of a good performance suspension is to balance handling, braking, and acceleration, creating a car that is both fast and fun to drive instead of a white-knuckle experience that scares you every time you turn a corner.

Hotchkis makes TVS kits and suspension components for lots of 1960s-70s cars including first generation Mustangs (Stage 1 kit for 1964-66 shown here); Camaro/Firebird; Chevy II/Nova; 1978-87 GM A-/G-body; 1966-69 Dodge B-body; 1970-74 Challenger/Barracuda; 1967-76- Dart/Valiant; and 1963-72 Chevy/GMC pickup.

It includes tubular front A-arms, adjustable upper/non-adjustable lower rear trailing arms, lowering springs, 1.5 Street Performance monotube shocks, tie rod ends, and required bushings and hardware.

If you can’t swing an entire TVS kit at once, all of the components are available separately so you build your suspension in stages.

A well engineered performance suspension package, like the Hotchkis Total Vehicle System (more on that in the slide show below), can address handling problems in one fell swoop.The stock suspension—even one that’s completely rebuilt—cannot handle the big doses of horsepower, larger wheels, and modern performance tires we love to add to our vehicles.That can lead to serious handling and steering issues that can be dangerous on the street and downright deadly on the track.The rig’s control computer uses various data sources and controls the impulse forces to each of the hydraulic actuators (one per post) Sensors mounted on the chassis monitor the vehicle’s dynamics and its reactions to the inputs.That makes the shaker rig a powerful tool for component testing.

Hotchkis sent us this primer on updating the suspension on classic 1960s and ‘70s muscle cars to make them handle like a late model.
