Patt Posted March 15, 2018 Report Share Posted March 15, 2018 I have the opportunity to buy a cheap Cayman sports suspension. I can't seem to find any information regarding the changes between the models. I guess due to the numerous options, I can't even find a firm figure for curb weight. Generally it looks like the Cayman is 20kg heavier although I guess that could even be more with the 18 way adaptive seats fitted. Do you think they would change the spring rates for that ? Keep in mind I'm generally 20kg heavier than most of you lot Thoughts please. Link to comment Share on other sites More sharing options...
Menoporsche Posted March 15, 2018 Report Share Posted March 15, 2018 That’s the difference of half a tank of fuel, or a heavy weekend bag. The car weighs 1300kg plus. I wouldn’t worry about it. Link to comment Share on other sites More sharing options...
Greenman Posted March 15, 2018 Report Share Posted March 15, 2018 I think there are some minor differences between base and S but otherwise I suspect the Cayman suspension is identical to the Boxster Link to comment Share on other sites More sharing options...

Greenman Posted March 15, 2018 Report Share Posted March 15, 2018 Extracts from SIT: I cant see anything that talks about Cayman/Boxster differences, but below does show that base and S are different (though no doubt many components will be shared: Chassis variants Like the previous models, the new Boxster and Boxster S models have different chassis variants. ::: 4.2 Front axle The front axle design largely corresponds to that of the 911 Carrera (991) and is tailored to the requirements of the Boxster with respect to driving dynamics. ::: Suspension strut The lightweight suspension strut consists of a double-tube gas-filled shock absorber and a concentrically arranged coil spring, which is in turn adapted to the different vehicle variants. Standard chassis - Boxster Spring rate: 25 N/mm Standard chassis - Boxster S Spring rate: 25 N/mm PASM chassis - Boxster Spring rate: 28 N/mm PASM chassis - Boxster S Spring rate: 28 N/mm The springs are color-coded to indicate the spring tolerance and the chassis variant.

Rear Anti-roll bar The design of the anti-roll bars in terms of diameter and thickness has been adapted to the vehicle weight and driving dynamics. The following variants are installed: Boxster Boxster S Standard chassis Manual transmission 21.7 x 3.0 mm 21.7 x 3.0 mm PDK transmission 21.7 x 3.0 mm 21.7 x 3.0 mm PASM chassis Manual transmission 21.7 x 3.0 mm 21.7 x 3.0 mm PDK transmission 21.7 x 3.0 mm 21.7 x 3.0 mm With rear differential lock Manual transmission 21.7 x 3.6 mm 21.7 x 3.6 mm PDK transmission 22.5 x 3.5 mm 21.7 x 3.6 mm Suspension strutThe suspension strut consists of a single-tube gas-filled shock absorber and a coilspring, which in turn is adapted to the different vehicle variants. There are two clamped threaded connections between the suspension strut and wheel carrier toimprove the camber rate.The springs are color-coded to indicate the spring tolerance and the chassis variant.Standard chassis - Boxster (manual/PDK transmission) Spring rate: 38/40 N/mmStandard chassis - Boxster S (manual/PDK transmission) Spring rate: 38/40 N/mmPASM chassis - Boxster (manual/PDK transmission) Spring rate: 44/46 N/mmPASM chassis - Boxster S (manual/PDK transmission) Spring rate: 44/46 N/mm Link to comment Share on other sites More sharing options...
