Just thought I'd put my .02 cents in here. For what its worth, anyone looking for a new or replacing their front brakes. The Z23 kit is a great product. I had some issues with getting the new pads into the existing calipers but the rotors and hardware, pads so far have been well worth the money and time.
I ended up having to buy new caliper guide pins for both sides ( $5.00/side), but the pads and drilled/slotted rotors have a huge difference from the OEM ones I had.
Im sure its been discussed a million times here already, I just thought Id share....
