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

Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

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.
POST 3Original post
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)
POST 4Original post
Almost everything except rear spring rates is the same. Minor difference. Why do you ask?
POST 5Original post
What Hardback said. TT is almost 200lbs heavier and requires different spring and damper rates. Other than that, the chassis, brakes are identical.
POST 6Original post
The lower front lip spoiler on the C4S "notches" up in the middle. The turbo front lip spoiler goes straight across.
POST 7Original post
Turbo has the thicker GT2 Sway bars as well.
