Been trying the BMW E30 at hockenheim ring, which is absolutely awesome! However I had to restart the race so many times. Could be I lose focus after a couple of laps, but I really think the grip is reduced quite quickly. After 5 laps I really have to be very careful with the throttle input. For setup I already increase downforce, reduced rear ARB. Increased toe in rear. But still the rear is so loose. These cars are sooo much fun the feel of the car is amazing. I hope someone has some useful tips for me!
You can't do much. They have ruined the Group A by reducing diff preload so now it's completely open and it causes overheating of tires spinning too much on corner exit (in particular on inner part of the tire that goes 10deg higher than the rest). This differential saga must end...
