Does anyone see a problem with using different pads in the front than in the rear for the Brembos?

I was looking at getting the Project Mu NS but they only had the rears in stock but they did have the B Force in stock for the fronts (but not the rears). The reason I'm asking is because I know that the B Force is a street/mild track and the NS is straight street so would there be any problems running harsher pads up front and milder pads in the rears? The guy said there shouldn't be any problems with it but I just want to make sure. Also he is giving me a pretty good deal on them since they're the last ones in stock for a couple months so I would like to know ASAP.

Also I'm getting the Stoptech slotted one piece rotors all around so I'm pretty happy . My car has been LONG overdue for a pad change.

Also does anyone know how hard it is to install rotors? Like does anything special need to be done or anything like that? I don't feel like taking it to the stealership and paying an arm and a leg for something I can do myself since the pads are already pretty easy to install.

 

When I go to the track, I use Pagid Orange pads on the front and Axxis Ulimates on the rear. This was reccomended to me by StopTech. The main reason for the difference is that the pagid pads are 3 times more expensive than the ultimates. Since the rear brakes don't do nearly as much work or see as much heat as the fronts, you can get away with lower performing pads in the back. As for changing rotors, I changed my entire brake system myself, and it really isn't that bad. You'll have to remove the caliper to get the rotor off, so you'll definitely need a torque wrench to put things back together, but just doing pads and rotors is easily a one day job. If you've run your car pretty hard, you might want to think of doing your brake fluid as well since you're taking all your wheels off.

 

You should be okay running pads that have a higher coeffcient of friction up front than in back as long as the two aren't night and day. You'll just have a bit more bias towards the front.

 

I run Project Mu b-force on the front and oem on the back (cause it didnt wear out) on my non-brembo and have no problems execpt for a minor squeak at low speeds.
