Morning chaps ... hope you are all well. The weather here in the UK is the worst its been for hundreds of years and the build up to the olympics is also causing complete mayhem here in the London area. Never mind and back to Porsche matters !

I am interested in collecting any spring rate data for 993 suspension setups. So far I have data given which may or may not be correct but at least a couple of them have been quoted multiple times on various forums so should be correct. It would be great if anyone can add anything as I might be specifying some custom springs for my PSS10 setup. I find that I would like it a little stiffer, maybe 15% 'by feel' but to work that out is quite diffificult especially as the front rear relationship isn't linear. Does anyone know KW and/or KW clubsport ?


M032, 145/217
M030, 165/285
PSS10, ~220/380
RS, 245/456
RSR, 375/550

Could you guys list your sources when posting this type of data? Makes it easier to distinguish real #'s from speculation.

I made it all up

Your values for ROW M030 don't match what Porsche says they are.

Did you measure these yourself or are you passing along something you read online as gospel?

Bill, Do you know what the rates for US spec 993TT are?Thanks in advance.I hope this is not viewed as a hijack.

Bill, did you pull these numbers out of your *** again? Such a liar

Bill Verburg

993tt is 29N/mm front & 55N/mm rear w/ 22/21mm swaybars

Bill uses the wizard-behind-the-curtain reference source.

I have found the stock and M030 #s to be the hardest to come by, the spring wire diameter, coil diameter and length are all well documented but not the spring rates and I don't remember where I got those from but probably from a set of RoW M030 springs I had sitting around a few years ago.. If you know better please do let us all in on the big secret.

The rest all came from various factory docs

Thanks Martin, I remember that Gert used to have the M030 rates posted but has since taken that info off the site,

It would be nice to see the factory specs
