I changed roll center at the same time too. And I don't know about yours but the traction is low to medium in our local track. I think it's generally easier to drive the car with thicker oil (less piston hole) but the available grip wasn't just there with my set up. The car was still drivable if I made sure to squeeze brake and throttle slow enough but by no means "easy to drive". The fact that it was ok at large sweeper but not ok at esses and hairpins made me more suspicious of piston locking.
This car's suspension is just so foreign and you have to take both heave and roll dampers into consideration at the same time and this makes me fight hard to get the right set up.
Anyway I hope I can find better one in my 3rd outing soon.
