I can confirm this - my Pagid Blues went on to my 4-pot calipers with no problem. I think your troubles stem from the fact that the pads you have are not for your car, they are being butchered to fit, so will never work properly. Get your money back, and get a proper set. If they get arsy, tell them the pads are not "fit for purpose". Good Luck !

 

Fitting a set of Pagid Blues to my WRX has been a nightmare.
The supplier could not get a WRX set ,but recommended that a bespoke set could be made by machining from another vehicle.Full assurances were given that the machined set would fit the 4 pot caliper.
Of course they did not fit-The backing shim plates did not align with the securing pins.
So back to the supplier -No problem mate we'll open up the holes to give the appropriate clearance.Fine.
Nope - opened the hole in the wrong positon.
Frustrated I managed to drive the pins through on 4 of the pads. I had bought 2 sets.
VERY tight fit on the rotor.But assumed everything ok.
Nope-Pads were now binding on the rotors obviously creating enormous heat build up.
Removed pads and returned to supplier.
Measured pad thickness -15.5mm should be 14.5mm. No wonder binding!
No problem mate we'll mill the pad to the correct thickness and redrill the pin holes again.Bloody Pagids always a problem with fitting.NOW they tell me.
Forget it mate I'll have my money back!!
Anybody else had this sort of problem?

 

Sorry to hear you have had so many problems, but, Pete at Scoobysport stocks pagid blues for the 4 pots ? so they are obviosuly not that hard to get hold of .
