Cross-drilled rotors are an excellent way to get increased braking
performance from your VW/Audi. All Cross-drilled rotors are not alike, however. At
UroTuning, we use high quality Zimmerman/Brembo rotors. Each rotor is precision
machined on a CNC machining center (not a drill press). Lots of holes may "look"
great, but every hole takes away a small amount of braking surface (swept area).
Too many holes creates a meaningful loss of swept area and ultimate braking
power, not to mention a loss of overall strength. Each hole in a SportTuned
Rotor is radiused to prevent pad galling, and the radius depth is the set to the
rotor's wear limit.
Each kit includes two rotors and Pagid Brake Pads.FITS: 1997-2001 Audi A4 1.8T Quattro
