AshDVS 20s on your P3???
The ride is going to suck!
Actually not , I had Marks Polestar as loan car a while back! Maybe having Öhlins suspension helped but it was good on 20s , a different brand of premium tyre than stock , maybe I was more vigilant of road nuggets , I certainly was on high alert most of the time albeit just home from Casa Iceton thence to work and then out to BMG but that was more to do with having a go of paddle shifting which for me requires a lot more learning as the power and responsiveness was epic , just being in the left gate of the shifter was enough for now.... (sort of power mode , ostensibly manual with the stick but paddles take over if you use them)
At least mine are XC rims not Polestar gold plated ones that may not be as strong. If I don't run them I'll probably put on the S80....it can do with some ride control the damn 4C is just shitfull on any setting , I prefer non 4C of the higher riding XC70 I just had as loaner! It was much more fun and in control compared to a much younger S80....
