I have two setups for the McLaren F1 shared. The one with 6.0 handling I have top 30 on Watkins short alt so this car has some real performance. It likes tracks that keep the speed up like Watkins, Spa and Silverstone. Generally speaking the 6.1 handling version will be better but some tracks the 6.0 handling is better. Great setups and a cool car, give it a try
