well, i'll put in my $0.02.
i got the master power kit in my car.
the positives:
the kit was complete
it supposedly uses all factory hardware, so you should be able to get new pads @ the local parts store
the not-so positives:
imo, tech support was difficult to contact or get a return phone call.
the kit only offers 10.75" rotors
if i had to do it over again, i'd do the f/m/j body setup here & get 11.75" rotors for (probably) less $$$:
