Chassis Resto/Mods

How to modernize the suspension on a resto project

For certain rare cars, restoring the components exactly to original is essential to preserving the vehicle's value. For most car enthusiasts, however, modernizing a restoration project makes a lot more sense. Called a resto/mod (which also refers to modifying the car), this approach takes advantage of all the improvements in automotive technology. There's no reason you can't have contemporary performance to go with that nostalgic style. It all depends on your style. Though not everybody may want this level of performance, the '62 Corvette shown here is a good example of just how far you can take the process.

The Setup

One common modification that's also found on a lot of street rods is to install Mustang II front suspension, either stock Ford pieces or an aftermarket performance setup as seen here. The chief benefit of this style of suspension is its adjustability for camber, caster and toe-in, something that's not possible on many older front ends. Also, the control arms on an aftermarket unit are usually made of tubular (rather than stamped steel) for increased strength. In addition, this Mustang II setup features rack-and-pinion steering (instead of worm gear), vented disc brakes (instead of solid rotors prone to fade) and coil-over shocks (for adjustability and reduced weight and size).

The engine mounts were also lowered in the frame, in order to squeeze in a new ZZ430 Chevy crate engine, which will be fitted with an 8-stack electronic fuel injection. The added benefit is a lower center of gravity for improved handling, but the frame had to be notched to clear the new driveshaft angle from the 5-speed transmission (to divvy up the powerband better than the stock tranny). The perimeter framerails were also boxed with steel plate for increased rigidity.

At the rear, the framerails were lopped off just before the kick-up section, which was replaced with a custom-welded tubular subframe. This new rear clip has a Ford 9-inch center section with a 411:1 gearset. The Ford 9-inch rear end is also popular among street rodders, but this particular one features a nodular iron case and an axle with disc brakes. In addition to a 4-bar layout, the rear suspension also has a diagonal bar or track locator (to prevent side movement) and an anti-roll torsion bar setup.

After the body is mounted on this resto/mod chassis and checked for fit and function, the car will be disassembled once again for painting and detailing. It will look virtually original, except for the big meats in the rear, yet furnish a whole new world of performance.
