I have the Tryolsport caliper sliders on my GTI VR6....there was a
noticeable but slight difference in braking under "extreme conditions"
ie auto-cross & high speed lapping. One needs to relube these sliders
often, and depending on the grease used they collect sand/dirt.

It is better to wear out than it is to rust out.
