Never had any issues installing them on new discs? I just checked and the front pad is a 19mm one. Ideally for the GT3 fronts you need 17mm. 19mm is a tad too thick when the discs are new. (like Pagid U8004 vs U8003, both fit but the U8004 can be very difficult to install unless your discs are worn a little).

The Endless is 18.5 mm fronts and rears. No fitment issues that I know of.

@TRD0524: I was referring to the Performance Friction ones. I think I'll give those a try.
