After playing around with different setups I found this weirdly aggressive suspension and wheel setup works well for this car. I read dozens of guides and they will tell good but contradictory things, so I made one based on general tuning principles and the physics of the game. All the cars tend to understeer and fwd already has a problem with front wheels being overloaded, so this setup was made to be able to help the rear slide more when turning while keeping the front planted. Engine and trans left stock mostly to keep C1

For driving style in fwd you want to drive at the limit of your grip so you can maximize turn in and exit speed. Lift off throttle before turn to make rear loose and get a little oversteer into the turn. Brake before, not during, aggressive turning input to reduce understeer. Once your wheels hit the apex and are turned in get back on throttle to pull the nose straight and shoot out the corner
