Handling vs grip

[totta Crolla]

There is not too much body roll, maybe 6 on your scale but there is a fair bit of rear to front weight transfer when lifting off, I find this really helps to balance the car.
I did try to stiffen the back end by adjusting the dampers to a stiffer setting and whilst it helped to promote oversteer the weight transfer was less and there were issues with lifting the inside rear wheel on tight corners.
I wonder if stiffer rear springs would be a benefit ?
Currently using 190lb fronts and 160lb rears.
