1984–87 Toyota Corolla AE86 (GT-S & SR5) chassis

This car is a unibody, so there's no separate frame to replace. The way to modernize it is to upgrade the original suspension, stiffen the body shell and fix the known weak spots.

Upgrade the original chassis

How it's built
Steel unibody
Front suspension
MacPherson struts with lower control arms, tension rods and coil springs. Rack-and-pinion steering.
Rear suspension
Solid rear axle located by four trailing links and a Panhard rod, on coil springs. The GT-S uses a 6.7-inch ring-gear axle with rear disc brakes and an optional limited-slip differential; the SR5 has a smaller 6.38-inch axle with drums and no limited-slip.
Weak spots
Rust appears in the rear wheel arches, rocker panels, floor pans, around the strut towers and at the hatch or trunk lip. Lowering ruins front roll center and bump steer, rubber link and arm bushings are usually tired, and the small rear axle is weak behind more power.

Stiffening the body or frame? We list 4 kits for this car, such as frame rails, subframe connectors and braces, on its Chassis stiffening page.
