Replaces the rubber caliper slider bushings with solid ones. I at the same time replaced my SS lines so I didnt' notice these specifically however people seem to indicate they do help. My pedal does feel firmer however that could also be the SS lines.
Looks like I'll be needing another new set of XP10's for the front, didnt realize that the heat on the brakes got so high that my pads (specifically front right) wore down to the metal on metal with the rotor, prolly from the 110 to 60mph braking on the front straight going into a left handed turn repeatedly.
So I've also started looking at the Brass bushings as well (incase my rubber ones are melted) (won't help with the heat) but I've read that they do help with spngy brake feel.
On Tyrolsport they are $100 ish!!! but for every other car including BMW's they are at most $50 ish dollars for a set from Turnermotorsports... why are the VW ones so expensive? what makes them so special?
Any pro's and cons? does the increased maintenance on the Brass bushings out weight the benefits? anyone else sell these besides Tyrolsport? wish I was near Turnermotorsports so I could just try different BMW bushings till one fits...
