Upgrading to 11.75” discs on the front?
Any reason why i should worry about the wilwoods not having dust boots? My car never sees rain or snow
I would say yes. I really dislike the fact that the Wilwoods don't have seals, although I heard that the more recent 4 piston calipers do have them. Don't own a set so I don't know. I recently pulled an old set of wilwood 4 piston calipers off a buddies car that had seized up pistons. Now, those were older design wilwoods that definitely did not have seals, and that car had sat for awhile before my buddy got it. But those things were complete trash.
So, just because the pistons are stainless doesn't mean they can't have problems. Dirt and junk getting into the caliper past the pistons is still bad, and you can still seize a stainless piston in an aluminum caliper.
For now im going to stay with my 1-1/32 master. Ok heres my options.
1. buy the complete stage 2 plus kit from doctor diff. $850
2. Upgrade to the larger piston calipers, braided hoses and buy the 11.75 caliper brackets along with wheel bearings and 11.75 rotors/pads. $450
3. Upgrade to the wilwood 4 piston calipers, braided hoses, wilwood caliper 11.75 brackets along with wheel bearings and 11.75 rotors/pads. $700
4. leave my current calipers (not sure if they are 2.75 pistons will have to check) upgrade to braided hoses, get the 11.75 caliper brackets along with wheel bearings and 11.75 rotors/pads. $380
Your #1 option should be more like $740, since you already have the spindles you need. And that would make it the same option as #3 really.
For me it would be #2 or #4. Check to see if you have the larger piston calipers already though first.
I run the Wilwood brake kit on my Dart. That includes the rotors, calipers, and master cylinder. I bought the car with the setup. The biggest issue with the Wilwood system is it severely limits what wheels you can run. The rotors use a 3.1" hub bore and that alone makes wheel choices difficult.

That's a different kit. The DoctorDiff 2+ kit uses factory 11.75" rotors, not a wilwood rotor and hub. So it's factory disks with a custom caliper bracket that allows the use of the wilwood caliper on the mopar rotors. No worries on the gigantic wilwood hub in this case.
I mean is there anyway the 4 piston calipers wont stop better than the factory style?
Is it possible? Yeah maybe. I can tell you the factory 2.75" calipers generate more clamp force than the 4 piston wilwoods do by the math. But it's not really a good comparison, because the single piston floating calipers will lose a lot more of that generated force because of flex, uneven application of the force across the pads, etc. than the multi-piston fixed calipers will. So I would say that in this case the wilwoods would likely perform better as long as they're functioning properly. Having said that, I've seen the wilwoods seize up. And I've seen the factory calipers work with some ungodly looking sludge for brake fluid. I would bet that the wilwood calipers would give you better braking with everything in new condition, but I don't know if in your application it would really be worth the extra money.
