    No need to sand the pads. I used new rotors up front and had my front ones turned before installing them on the rear. I think the bias would be all wrong with the same size front and back.

      Is it important to install larger rear discs at the same time you install larger front ones ? I am thinking if you install harder braking (larger) front discs, this might cause the rear to fish tail under hard braking if it only had the OEM rear discs ?

      thanks,

        70%ish of your braking is handled by the fronts to begin with.. I dont think this would be affected nearly as much I believe are cars are equipped with proportioning valves on the brake hard lines themself... I believe these are there for this exact reason.. to help displace the difference in pressure due to different lengths on brake line itself..

        I could be wrong but I don't think it i will adversely affect it under "normal use" Now if you are going to track the car every other weekend..then maybe further down the rabbit hole you must go.

          Just to add my experience, I have had the NPG kit on my car, front and rear, for about five years. The brakes perform just fine. I didn't notice much difference in braking performance at normal speeds, but hard braking I would say is a bit better. They look good with the larger rotors, and installation isn't too hard. The front kit is very easy. The only thing needed is to drill the stock mounting bracket holes a bit larger as the bolts that NPG provides to attach their brackets are larger. The rear kit takes more work. First, you need to grind the inner surface of the stock brackets to gain more clearance, and since these are made of hard steel it takes a lot of grinding. I tried various methods and found that a carbide bit in a die grinder worked best. Be prepared for a lot of grinding and test fitting. Second, I had the inner rotor hats turned down .020 in order to fit over the hubs, and this worked fine. When I do my next brake job I am going to grind down the edges of the hubs so I won't have to pay for the machining. Third, I had to have my rotors turned down. Once I had everything assembled I could hear some scraping and figured that the pads were too thick, so I had the rotors taken down .010 on each side, and this solved that problem. I used EBC red pads. I plan to use Mintex pads the next time, I don't care for the EBC pads all that much, so maybe they will have a bit more clearance? If you have any questions, feel free to ask.

            Is Nautilus still the best place to buy the big brake kits ?

                Does the large front brake kit work with E1 stock rims ?

                  Pretty sure the kit was designed to work with factory wheels. I can but E0 wheels on the front of my car. I recall seeing photos of other cars with E1 wheels on them.

                      Your best bet these days is probably Summit Racing Equipment. RockAuto may have them but it is hard to tell if they have the right diameter given the sparse information provided on their listings. I checked the BAT website and they don't have the front rotors anymore.

                        Thanks for the recommend. I see a bunch of 300mm "Focus SVT" rotors on Ebay. but I would rather be sure about purchasing something so important. Focus SVT is 4-bolt, correct ?

                        I emailed NPG with some questions over a week ago but havnt heard anything. Do they only answer the phone ?

                          The Focus SVT is the exact same 4-bolt pattern as the Contour/Mystique/Cougar.

                          It has been the experience of many that it is best to call NPG instead of e-mail.
