Cheers all -

For a big Porsche specs database I'm putting together, I'm looking for stock rear sway bar sizes for the early 997s.

Ian Kuah's article in Excellence on the C4S (issue #141) lists the front sizes as the following:

Carrera 2 - 23.6 x 3.5 mm
Carrera 4 - 22.5 x 3.5 mm
Carrera 2S - 24.0 x 3.8 mm
Carrera 4S - 23.6 x 3.5 mm

However, there was no mention of the rear sway bar sizes. Anyone have that info?

Thanks,

Superb, thanks. I'll go ahead and assume those sizes go for both RWD and AWD variants?

Best,

For the 4S I do not have the actual sizes
Front:
The anti-roll bars have also been redesigned on account of the available space
at the front axle as a result of the four-wheel-drive concept.
Rear:
The anti-roll bar for the 911 Carrera 4 has been retuned to ensure well-balanced driving dynamics.

I measured a few rear sway bars with my micrometer on '09 cars today, and here's what I came up with:

C2 - 18.5 mm
C2S - 19.6 mm

C4 coupe - 21.7 mm
C4S Targa and Cabrio - 20.8 mm

Looks like no change on the C2 cars. The bigger bar on the C4 vs. the C4S was a bit of a surprise.

Figure a .1 mm error factor on those C4 measurements, but I'm reasonably sure they will stand as accurate.
