I don't have the loose rear-end anymore in high speed corners. It just seems the harder I go the better the car gets. Bear in mind I'm running all the latest parts. I'm actually 1mm less shims under the rear upper arm mounts too. The car is getting better every run.
Roll centres were definitely too low stock. I've gone up to med-high roll centre on rear and 2mm shims all around. When running stock, the amount of wear on the carbon were a dead give away the rear was washing out hence loose rear on-power.
I just need to try these new parts once I've finished experimenting with the XQ1
