My friend at TDW help me put the KW V5 back on but this time with 14kg/10kg Swift springs. Car feels way more neutral now and still have plenty of front end grip. It handle bumps and manage car weight pretty well and overall gives a lot more confidence. 

I had many laps with predictive in the low 1:21 but they all got ruined by traffic. It's expected for any open lapping day where there are no run groups and large differential in lap time. A 1:21.9 turns out to be PB of the day which is not too bad on 4 day old SC3 tires that's almost cording.
