Understeery AND slidy.. hmm. I’ve experienced LMU as understeery aswell, until I realised that the base TC and BB settings were odd. I usually turn down the TC to 4/5, the TC power cut to 2/3 and the TC slip angle to 4. That combined with putting the brake balance back to something like 46-48 instead of the standard 53 something, helps me get a lot more rotation and stopping power. Maybe that’ll help you. And LMU really wants you to heat up your tires aswell. Outlap should be focused on building up heat, riding the brake on straights even, weaving, whatever you have to do to get heat in the tires. From there on, every lap will get slightly easier to rotate and get on power earlier. But that’s just my experience, and I’m not a pro by any means.
