This question is for DD purposes...

Do I have to use the same rotors on the rear as I use on the front of 2003 S-Type R...IE If I am using drilled and slotted rotors on the front can I use just slotted on the rear (and still use the same pad type)?

Any performance danger issues?

 

Yes.
I don't like drilled rotors for the street. Inspect them often for cracking at the holes. Slotted is considered much better.
See the attached picture of what to look for.

Brilliant pic!

 

OH POOP! I better check mine considering the flogging I give them.

Not a money thing. They are warrantied for life against warping or cracking.

 

Is that picture from a car or motorcycle?

 

I am soooo impressed you even thought to ask. A tech in action

 

I already have the slotted and drilled for the front application...but that is a great pic, thanks for the heads up...definitely keep an eye on them...

I drive the car fairly hard from time to time, so I went with the drilled because during the summer the brakes get pretty hot...

 

The rotor pictured is from a drilled Lincoln LS front rotor. Or at least it is suppose to be!! I did not take the picture.
