NPG upgrade brake kits

[MadDog]

Anyone have any experience with the NPG upgrade brake kits ? I was thinking of getting the kits to mount 300mm front rotors and 278mm rear rotors, but the description indicates some fitment required. I emailed NPG a while back on what "fitment" precisely meant, but I have had no response.

As for the rotors, are there any preferred makes ? I was thinking of plain rotors with slots (not drilled).

thanks,

It means some mods will be required. I don't believe they're that extensive. Take a look around the suspension & brake forums. You should find sumthn. And yes, the npg kits work perfectly well

The front brake adapter kit bolts right up using the 300mm rotors with no modifications needed. Bingo bango.

Using the 278's on the rear is more of a hassle, as the 278mm rotor thickness is CONSIDERABLY greater than the original rear rotors, so you have to do some grinding on the insides of the caliper bracket to get it to clear. You also can't use new pads with new rotors - again, because the thickness is too great for the caliper to fit around it. So you have to either have the rotors turned down a little, or shave the pads down. And finally, the inside diameter of the 278mm rotor hat is slightly too small to fit over the rear hub, so you have to either grind a little on the inside of the rotor hat or grind a little on the outside of the hub, to get the 278mm rotor to seat on the rear hub. AND once you have everything fitting together, the pads only sweep about 65% of the rotor face, so you should probably coat the unswept portion with some high-temp brake paint to keep the rust away.

The only thing I have to say is the rear pads or rotors do NOT need to be shaved down. Same goes for using the Focus SVT front rotor on the rear of the Contour. Grind the brackets. New pads. New rotors. No problem.

I should of mentioned first that I am doing this because my rotors are thin and should be replaced soon. This is not a track car, nor am I tough on my brakes but I might as well upgrade if I am there.

So if I understand correctly:
1) 300 mm SVT Focus fronts + NPG brackets = no problem
2) The 278mm rear rotor might require some shaving to fit over the rear hub (1 answer yes, 1 answer no ?)
3) grind down the rear caliper bracket interior to clear the thicker 278mm rotor - am I thinking of the correct part:

Is there any danger by installing the 300 fronts and not putting on the 278 rears at the same time ?

As always, I appreciate your help.

When installing the rears on mine, with the caliper piston COMPLETELY bottomed out, there was no way on earth that a loaded caliper would fit over the new 278mm rotors I had just bought. Just doesn't open wide enough. Not sure why you didn't have the same issue; maybe it depends on the brand of rotor and the brand of pads, and the thickness varies.

My Guess would be that it depends on brand of pads. The ones I used with my 300mm rear kit were used pads that I had on for a few months before and they cleared without issue. Its that close that brand thickness or pad material could make it sway eitherway.

Any vendor recommends for the 300mm fronts ?

I ordered the front and rear kits for my car a couple of weeks ago from NPG. The kits came in yesterday and Joey emailed me the files for installing them today. He answered the phone the first time I called to ask about the kits and he called several times to clear up the delay in shipping the kits to me. He was on his honeymoon so I understood. Once he returned, he shipped my kits promptly and kept me in the loop by email with a tracking number. Just thought I'd let anyone know who was thinking about ordering from Nautilus Performance.

Let us know how the fitment goes as I am considering the NPG kits.

It will be probably next month as I'm also rehabbing a set of wheels. As soon as I get the wheels finished I'll get to the brakes.

Well, I thought I would post some pics of the finished product and let you know of how it went. The front was a breeze. I had to grind a small amount on the strut mount for the bracket clear and enlarge 2 holes

Well, I thought I would post some pics of the finished product and let you know how it went. The front was a breeze. I had to grind a small amount on the strut mount for the bracket to clear and enlarge 2 holes. Otherwise, a piece of cake. The rear was much more work. Grind some on the rear shock mounts. Grind the inside of the rotors, which were the old front ones, to get them to fit. Grind some, install, check for clearance, repeat several times. Grind some on the caliper mounts. After that, I needed to cut the mounting bolts down from the kit because they were bottoming out on the caliper brackets before they were tight. The fronts were tapped all the way through, the back, only halfway. Once I completed one side, I was able to do the other rear in about 40 minutes. All and all I'm happy with the finished product. It looks so much better with the larger rotors and I can't wait to mount up the other wheels to show them off.

Did you have to sand the pads down on the rears to make them fit? Or turn the rotors? Anyone tried the 300 kit for the rears?
