I have basically swapped a gt3 into a c2...gt3 shares the c4 chassis.

Now knowing the engine limits, the turbo was probably a better deal..

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.

C4S is wider but afaik there's no difference between normal 2 and 4.

POST 1 / ORIGINAL POSTEROriginal post

How much wider is the C4 over the C2...?

POST 2Original post

Aren't they the same width? C4S is wider but afaik there's no difference between normal 2 and 4.

POST 4Original post

All c4�s are about 1.8 inches wider than the C2. It doesn�t mayter it its an S or not.

POST 5Original post

I don�t think my 2001 c4 is wider than the 2003 c2 convertible my wife has. I think the C4S is as wide as the turbo 996 I have.

POST 6Original post

According to excellence .1 C2 69.49" .2 C2 69.68" C4 69.49" C4S 72.05"

POST 8Original post

The C4 definitely looks wider. Interesting to know it's not.

POST 9Original post

So what's actually wider? Are they the same chassis but the 4/4S has just wider rear fenders/body? Are the wheels spaced out wider and actually provide a wider stance? I know the C4S runs a different offset in the rear and has a wider rim. My question is, were the rear fenders widened to accommodate this or was there more work done to the chassis. Working on a C4S before, the engine bay seemed as tight as a C2.

POST 10Original post

According to this video the Turbo is wider. I linked it right where he discusses it. And yes, I'm researching my next project. You Tube

POST 11Original post

Yes - 60mm wider than narrow body. I'm still curious around the how. What was done to make it wider.

POST 12Original post

Remember the GT3 is based on the C4 chassis, and is considered a narrow body 911. Only the GT2, Turbo and C4S are wide body variants. The how is the wider rear fenders for the inter-coolers.

Its just the rear fender skins. The cabin and engine bay measurements r the same inside the structural unibody rails. The area under the rail is bigger to allow for the intercoolers. The c2 and c4 r the same other then the frunk area to allow fir the awd. The frunk area is identical for the c4, c4s and turbo. I have basically swapped a gt3 into a c2...gt3 shares the c4 chassis. Therfore they r the same. There r also sheet metal differences around the engine lid for the c4s and turbo too, but the c4 is still the same as the c2 in that area.

POST 15Original post

I always think of the C4S as �turbo look.�

That's what it would have been called in the air-cooled days .

POST 17Original post

Hmm ,,,The C4S gets you the wider rims, wider stance, the look of a turbo and in the day, less cost. Now knowing the engine limits, the turbo was probably a better deal.. LOL

POST 18Original post

So an 2001 C4 is considered a narrow body car then.....correct?

Yes, same body as the GT3.
