If you’re basically never going to the track then I wouldn’t say you intend to track. People take stock cars to the track and don’t have issues, even aftermarket coilovers intended for the street can attend track days with no issues. When people say “track” more often than not it’s not an actual track day, it’s a non racing / play day on a track - 10-20min sessions.
When a manufacturer or equivalent hears you say track days, they assume you mean full on racing with subjecting the car to a lot of repetitive abuse for extended amounts of time.
i have 6/6 on my Wrx and I would say it’s pretty stiff, I wouldn’t want it any stiffer for a daily driver ( I could probably soften my damping more if I had slightly stiffer springs tho). Factory STI suspension is only around 5 I believe
