Get rid of the rear toe in. Increase the dampers to extension 9, compression 10; or extension 8, compression 9. Lower the LSD to 5/5/5 then increment 5/6/5, 6/6/6, 6/7/6... so on until you find some minimum value that works, you can scale that up in ratio to a higher setting if needed later. Aero, I'd start at maximum for testing these other variables, then gradually scale it down and find if there is a performance threshold. Also, with the dampers boosted you should be able to run camber at higher levels also, so maybe try 3.0/1.5 with 9e/10c dampers, etc. Also explore other camber ratios to compensate for over/under steer issues as they arise.
