has anyone used psi tunings new polybush top mounts

Yeah Ive got a set on my a3. Can't really tell much difference to be honest. On coilovers so the 10mm drop could have been achieved by adjusting them and the fact that although they state to work with standard top mount/caps I had to invest in some polo top mount/caps to keep everything flush under the bay. Personally I would recommend just getting standard replacements or cupra r items. Not to mention my customer service from PSI left something to be desired. Certainly wont be ordering from then again.
