2007 Sonata 2.4l, 4 cyl., GLS

Is there any reason why I can’t use slotted brake Rotors and the appropriate pads on the front brakes? I’m thinking that if I’m going to pay a lot of money for parts they may as well be performance parts

Performance brake rotors/pads are more expensive than the stock components. So unless you drive the vehicle in a manner where you can benefit from the upgrade of the brake components, it’s a waste of money.

No reason you can’t, but also no reason you really need to.
