Dashpots are commonly used in dampers and shock absorbers. Coil springs were used with hydraulic telescopic shock absorbers. It included coil springs and hydraulic telescopic Koni shock absorbers. Damping was provided by hydraulic telescopic shock absorbers on all four wheels. Separate shock absorbers and coil springs. Vehicles typically employ both hydraulic shock absorbers and springs or torsion bars. Porsche substantially revised the suspension, replacing torsion bars with coil springs and shock absorbers. The suspension used standard 308 components with adjustable Koni shock absorbers. Hydraulic telescopic shock absorbers were in the front and rear. Like the PT-17, reinforced suspension (torsion shafts, shock absorbers, and elastomer bumpers) are used. Stacks of rubber shock discs act as shock absorbers. The suspension consisted of conventional leaf springs with hydraulic shock absorbers. Chemicals such as UV absorbers and stabilizers are added. Suspension includes Bilstein shock absorbers on manual versions only. The rear suspension for both comprised leaf springs with bias-mounted shock absorbers.
