I've been really tempted to bite the bullet on getting the Polestar upgrade (MY17 S90 D4 R-Design) however, my fears on insurance have swayed me against this....
I may be lucky on insurance this year, but next year? What if an insurance company refuses to insure?
Yes, the upgrade may make the gear changes smoother, less delay etc but tbh its not that bad..... the stock D4 has enough oomph....
If only it was a simple (permanent) "within 5% power uograde therefore no change....."
