F1 Car bug

Some how the Indy car has better handling than the f1 car and they are both stock every turn I take with the f1 smoothly it slides but on the other hand the Indy car has better handling around a turn than the lotus e23 f1 and doesn’t slide. I compared the f1 and the Indy cars lateral g and handling
F1 9.8 handling 1.86 lateral g s at 60 and 120 2.96
Indy car has 8.9 handling 1.73 lateral g s at 60 and 120 is 2.40
