Steering a bit rough
 

I recently took my car in (RC 350 F Sport \ 2015) to check what this grinding noise on my brakes was and I received a loaner. The loaner was the same car in a different color and the steering felt so fluid compared to my car as well as the paddle shifters and shifter. It feels like my car is a bit stiffer in turning the wheel, shifting feels hard as well as the paddle shifters.

The brake issue I'm resolving this weekend, it's just pads are worn and rotor has a small lip (They wanted to charge me 400 bucks for replacing pads / resurfacing rotor).

I just wanted to know if you guys had any idea why turning the steering wheel is harder than on the loaner I got. They're about the same mileage. Mine is 13k, there's was 11k)


Thanks,
Thomas
