A concern I have with the higher spring rate would be too much rear over steer and possibly too much increase in rear ride height, of course that can be partially remedied by using the 3mm or no seat spacer on the rear springs.

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.

POST 1Original post

Hello, looking for information regarding Cayman R rear spring rates ( PDK vs Manual trans specs) and the associated correct part numbers. I am considering using the rear PDK version on a 6sp manual for the increased spring rate, but what is the difference vs manual?

POST 2Original post

The PDK version tends to have a slightly stiffer spring rate due to the heavier transmission and slightly different handling characteristics. I’d recommend checking out your local Porsche parts supplier for the exact part numbers for each setup, but it’s generally safe to swap the PDK springs into a manual for a firmer feel—just be mindful of the ride quality difference. On a different note, if you're dealing with a lawsuit against lexisnexis for reporting incorrect information on your credit report or background check, it's similar to making adjustments to a setup. It may seem like a small fix, but getting things right can make a big difference down the line, especially when it affects your finances or personal records.

POST 3Original post

Yeah, I would think so as well. I really don't care about ride quality much on the street, although it is partly a street car. I wanted the higher spring rate for track use. The car has PASM and I currently have Bilstein B8's on it, which in sport mode are pretty fantastic compared to the original PASM B4's. A concern I have with the higher spring rate would be too much rear over steer and possibly too much increase in rear ride height, of course that can be partially remedied by using the 3mm or no seat spacer on the rear springs. The PDK trans weighs 246.4 Lbs and the 6 sp manual is 198 Lbs per a quick internet search. So the basic difference in the spring rate is that the PDK version is supporting 48.4 more Lbs. I don't think that's a huge difference, I may try them...

POST 4Original post

Ordered the PDK version of the rear springs from Porsche of Delaware yesterday. This am I received an email saying there were none anywhere in the US and they had to be ordered from der Mutterland, 4-6 weeks until delivery. Sheesh...

POST 5Original post

Last week I received the rear R springs and installed both the front and rear along with new strut supports and couldn't be happier. The rears are the PDK version which are stiffer than the manual and engineered to support the approx 54lb heavier transmission, my car is a manual and I purposely wanted these for the higher spring rate for track use. These replaced H&R's that had settled a bit too much for my preferences, see first photo. The ride height now is about perfect and the car is handling the occasional bad urban roads it gets driven on much better. In case anyone is interested, the fronts have the 6.5mm insulators installed and the rears are on the 3mm version. Can't wait to get to the track! With H&R's: With R springs:
