this car is not an easy one to drive, don't blame the setup if you're trying this car for the first time. be patience and build your condifence lap by lap

i did this lap with these temperature just because i do every hotlap in these conditions but the setup is good even with 29° air and 38° track (round 2 logitech mclaren challenge official temperatures) my pb with 29° 38° is a 43.6. 

i recommend to use TC 3 if you're struggling with the rear and you can also use less rake ( 1 or max 2 click less in the rear height) 

if you also have understeer in S2 you can use less differential but i advise to use mine that at least have a good traction out of the corners that help you in the last sector.
