zman2002 C4S

Do the C4S and the Turbo share the same suspension (are they interchangeable)?

Byprodriver

I was present at the Porsche C4S press introduction in 2002 where Porsche PR claimed the C4S was mechanically the same as the Turbo except for the engine & rear spoiler. I'm not sure if that translates into the exact same part# in every case or if that changed in later years.

Hardback

Short answer is no. Part numbers are different. Turbo is heavier than 4S.... different setup.

(When I researched the X73 suspension there were different part numbers from 4S to turbo)

Almost everything except rear spring rates is the same. Minor difference.
Why do you ask?

What Hardback said. TT is almost 200lbs heavier and requires different spring and damper rates. Other than that, the chassis, brakes are identical.

The lower front lip spoiler on the C4S "notches" up in the middle. The turbo front lip spoiler goes straight across.

Turbo has the thicker GT2 Sway bars as well.
