I did a few hours of driving today, hopefully this feedback will be useful.
Through uphill hairpins, the inside rear wheel spins more easily. I expect this is due to the reduced droop travel.
There are several mid corner bumps that used to bottom out the car quite violently. The rear is now stiff enough to resist this but the front tyres still touch the inner fenders over the biggest hits. Does removing the inner fender liners give much extra clearance?
It's hard to give feedback on the balance of the car as the grip level with semi slicks is high. Through slower corners it rotates a little better and turns in more sharply. At low speed the car feels more agile, however in longer bends the reduced roll angle gives less feedback.
In terms of comfort, for the most part I find the spring rate easy to forget, and the bucking from the driveline is less irritating now that it is more strongly damped. I wouldn't recommend them for a daily driver over rough roads, but for a weekend street and track car I think they are acceptable.
I will add some more comments after I have been to the track.
