Me thinks he wasn't payin enough attention to what he was replying to.
Drilled slotted won't really make a bit of difference in how you stop on the street. on a street vehicle they're really just for show, which is fine, just don't trick yourself into thinking they make a difference in stopping power. Combined with better pads thy may make a difference but you will likely see the same difference with plain rotors and the same pads.
I'm not aware of any big companies currently making a kit for bigger brakes that will fit on your truck. There are a few other options though when they are available, though for either you need 95-97 spindles, and for one matching calipers and brackets. Problem is they aren't discussed much over here, I'll give you some general info but for more on them you'll have to go RPS.
First and probably cheapest is a bracket that will allow you to run 12" Sport Trac rotors. This is the one that requires the 95-97 calipers and brackets. It's not a problem as they are pratically identical to the sport trac units, the added braking power comes from the larger rotor and placing the caliper further from the wheel center. I managed to get a set of these brackets from the maker's last run and they look great, problem is he may not make another run for a while. That said he may have a set still on the shelf. They guy you'll want to talk to over there is Gumby and the thread is here:
12" brakes for 95-97 spindles
Now how do you feel about 13" Mustang Cobra Disc Brakes? If that gets you interest then you'll like this, there are at least two (possibly three) kits that allow you to run these. I'll warn you though this is a bit more expensive than the 12 inch brakes, all you are buying in these kits is a bracket and hub that allow you to mount the components to your truck, you still have to buy the cobra brake components. One kit is made by a user over there named TeeRev, there have been a number of these bought and run with nothing but good results. What he does is machine a bracket from 6061 T6 Billet Aluminum if that means anything to you, simply put very strong stuff, to mount the cobra calipers to your spindles. He then takes a new brake rotor and machines off the rotor portion so the hat is left as a hub similar to what is on the old mustangs. He machines them such that your track width is not modified. Mount the hub like your old rotor then slide the cobra rotor onto it. Problem is he has sold all the kits he already made and is not interested in making more to sell due to bad business people saying they would buy and didn't leaving him to foot the bill until he could sell them. We managed to work out a group buy if we can get 10 buyers willing to pay about half of the money up front to help cover cost of getting materials. For more information see this thread:
13" Cobra brakes for your 89-97 Ranger & 99-03!! for the group buy see this thread:
13" brake kit Yeah I bitched a lot in there, but they agreed to the GB. I'm on the list and we have 6 more people to go. Personally hoping that if we might have 5 with the same type they'll cut us a break and make them anyway.
The other option for cobra brakes just popped up the other week with very little info, and only one user. Who knows how they'll work, or if they'll work on anyone else's truck. Guy started talking about them last summer then disappeared for a year,and still hasn't given a price for them. I'll give the link to be fair but won't recommend them:
Another 95-97 Spindle Brake upgrade?
As for the rear brakes I see you are going to a V8. You could upgrade to an Explorer 8.8 with disk, but it's probably a little wider than what you have now. I think you could also put those disks or mustang rear disks on the axle you have now. you'd have to search on those though.
Long post but that's about all the help I can give you.
