Pagid E1 blacks

Is anyone using these pads? The parts company owner uses them on his boxter S, his employee says they are street pads easy on the rotor and not noisy. All I can find in searches are pagid black rs7, r421 and rs14.

Still hoping one of you guys has the 411 on minimizing fluid leakage after caliper removal or tips on how to prep the entire brake system before caliper removal

Thanks...
