I am trying to find the OEM spring rates for the 997-3, I looked in the manual no go. anyone know or how I can find them?

If you take the wheel off I believe it is written directly on the springs.

part number is written - dont think the spring rate is - may be able to use it to call h&r

I too have searched, and not found, rates for 997 GT3, but probably should be close to those for 996 GT3?

Stock 996 GT3:
Front: 225 Linear
Rear: 550 Progressive

I will makes some calls to Porsche through my dealer to see if we can get the data and I will post if I find anything. I wish they would give you more of this info in the manual. this car is supposed to be a track tool well lets get some specifications in the book to work with.

Yeah, if it's a track car then they should provide data. Feel like asking them for downforce and drag information on the GT3, GT3 RS, GT3 Cup, and GT3 Cup S?
