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.

Outcome without a verified action link

Rear springs do fit coupe or cab - no difference.

POST 1 / ORIGINAL POSTEROriginal post

So I understand that the various lowering spring suppliers specify different springs for the coupe vs. the cab/targa and this is due to differences in weight, but does anyone know why they specify a different spring for a C2 car vs. a C4 car?

POST 2Original post

I would guess it's also to do with the C4 being heavier than the C2.

POST 3Original post

its the differences in the weights of all cars, c2 manual, c2 tip, c4s manual, c4s tip, all 4 different weight, 4 different springs. I think the turbo and c4s are interchangable

POST 4 / ORIGINAL POSTEROriginal post

So is there a huge difference in weight between a C2 cab and a C4 cab?

POST 7Original post

C4/C4S/Turbo have a different front suspension design than C2.

POST 8 / ORIGINAL POSTEROriginal post

Hm, interesting, I did not know that. So apparently the suspension was tilted slightly towards the rear to make room for the 4WD drive shafts, etc.... So were the OEM springs different for the C2 vs C4 cars as a result?

POST 9Original post

C4 has completely different front hubs because of the AWD. The upper perches in the front are the same for C2/C4. The rear suspension mounting points are the same for C2/C4. I assume front springs are designed to hold more weight for the C4. Rears might be more heavy duty too.

POST 10 / ORIGINAL POSTEROriginal post

Yes, I've been able to confirm that the vendor made an error and they are not suited for a C4. The vendor has been good so far and is willing to correct things for me (waiting for their update). Having said that, if someone is interested in them, shoot me a PM. I'm in Canada, eh. Question: These are for a C2 cab. Wonder if they'd fit a C2 coupe with no issues? Although, they do sell springs specifically for a C2 coupe. Rear springs do fit coupe or cab - no difference.
