Hi yall, I have been dialing in my 2008 S over the past year and I have ended up with 3 clicks from hard. I have BC coilovers and they are the BR series with springs FR 18k and RR 10K.

BC suggests I don't go much further because it will decrease damper life.

My set up may not suit your needs or expectations but it's a data point for you. I'm sure my preferred damping is different than yours but that is what makes adjustable dampers so nice!

Thanks
Michael
