1992–2000 Lexus SC300 & SC400 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
- Double wishbone suspension with coil springs and an anti-roll bar. Power rack-and-pinion steering.
- Rear suspension
- Double wishbone independent rear suspension on a rubber-mounted subframe shared in design with the Mk IV Supra, driving the rear wheels through a subframe-mounted differential.
- Weak spots
- Rust is uncommon but can appear in the rear wheel arches and lower panels on cars from salted regions. Front upper control arm bushings and ball joints are a common failure, and the soft subframe and differential mounts allow wheel hop.
Stiffening the body or frame? We list 2 kits for this car, such as frame rails, subframe connectors and braces, on its Chassis stiffening page.
