The night pager sucks. Its hella janky and the pad over hangs from the edge of the rotor a little.
The only BOLT ON solutions you have without some custom fab or modification are the AZP wilwoods or the Doward Mustang brakes.
Both are 13" brakes
Wilwood is a 4 piston caliper- Mustang is a 2 piston caliper
Both include all hardware and bracketry
Mustang costs about half what the Wilwoods cost
So those are your bolt on options. Obviously price is proportionate to how many pistons you want. The Wilwoods are amazing, i have them on my MKIII, very good fitment, excellently engineered by Andy.
The Mustang brakes are also an awesome "bang for buck" upgrade. 13" brakes for about $700 out the door? Great. Of course you only get 2 piston calipers instead of 4 pistons, so the braking isnt as tight as the Wilwoods but its still a HUGE improvement over stock and costs half as much.
So take the differences into account and figure out what works best for you. Doward's mustang brake GB is over but I still have several brackets if you decide to go that way
