Default vented rear rotors for 2007 300 touring?

My wifes rear rotors have very bad scoring(grooves) on both sides of the rotor. I noticed the fronts look brand new and they are vented, the rears are a solid piece. Does anyone make a vented rotor for the rear?

I've been looking online, but no one says they are vented, they say you will get solid or vented, depending on what you have on your car.

The brakes have a annoying pulsation when gently applied!

Well I got an email back from centri brakes that said if the vehicle came with solid rotors, then that's what I have to replace them with. So basically I'm screwed with ****ty brakes.

Who puts solid rotors on a car? stupid!

on the rear I can understand them being solid
The fronts should be vented because as much as 80% of teh stopping power is from the front braking system
Remember when stopping a car, the weight of the vehicle shifts to the front which is why you get nose dive under hard braking.
That will explain why the front rotors are vented, slotted or cross drilled and even larger than the rears with some cases having numerous pistons. (4 pistons as opposed to having two in the front)
Because of weight shift during braking, less rear braking is needed which maybe why the rear rotors are smaller and/or solid rotors. And in some cases will have drums in the rear instead of rotors
An easy fix is to purchase some slotted rear rotors and and some quality rear pads

I understand the fronts should be vented, but my mustang has vented front and rear. Apples and oranges I know, but this car is heavy and needs all the stopping power it can get.

This is what the rear rotors look like. Not sure if those are actual groves in the metal or imbedded pad material. I might replace the rears with slotted rotors and better pads.
