i got the 10k/8k spring rates, and initially set the firmness to 16 (middle of the pack). i noticed the ride is exactly if not softer than stock suspension. i came from f-sport springs and it was a night and day for me, f-sport springs were a lot more firm than that. then i changed the setting to 14, this time it's exactly like my previous f-sport springs. i did not know those settings were this sensitive. for those with 10k/8k BC coils, what firmness are you on?
