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.

Anyone know what the spring rates are for H&R 30mm lowering springs for a 996.1 C2 please? Have seen the Vogtland version seem to be relatively low rates and thinking they may be more compliant for crappy UK road surfaces?
Hi, no idea what the rates are but I have a set of these together with Koni Special Active dampers and an X74 geo setup. Around the awefully maintained B roads of suffolk it is fantastic, I do occasionally ground but only in so much as I have to look out for ridiculous dips and go slow over huge speed bumps, not an answer to your question but hope it helps.
Which springs do you have? H&R or the Vogtland ones?
Well I could have been clearer I guess, but H&R.
I have this spreadsheet from a 996 thread on Rennlist. It lists mainly 997 though for standard, but don't think there is much between 996 and 997. But seems like H&R are a smidge firmer than standard at the front and a smidge softer at the rear. Spring rate spreadsheet
H&R also do two springs, blue and black, the black one is firmer and lower and also sold more in the States from my research.
Not aware of that in the UK, mine appears to be the only H&R option, they are blue and an x74 30mm lower.
Yeah, same here. It seems there is discussion about it on the US forums, but older posts, so not sure if this was ever the case or just people getting it wrong. I thought their "track" springs were red. I mentioned it because that might be why there are 2 rates on that spreadsheet? I just looked on the H&R site and it only has the one spring listed now, and coilovers of course.
Thanks for all the comments. That spreadsheet was really helpful and shows the Vogtland springs to be quite a bit weaker than the others and strangely less than standard which surprised me. Thinking H&R is likely going to be my choice I think now.
