On both products there is a quality issue.

Similar to brake pads. You can get cheap pads or go with MetalMaster, ceramic or multiple combinations.

I have been looking at front rotors for a while since my 1987 924S is now at minimum at 19.1mm thickness (my rotors have it stamped-Pelican says 18.5mm to replace).

The inexpensive rotors will stop the car. There may eventually be slight vibration, warping under sever-continuous braking (heat build up) or rust. The steel brake lines will, under normal driving conditions, should not rupture or deteriorate. If you "occasionally" feel the need to push your car, you may be more comfortable (stopping) with the specifications of OEM performance standards and material quality.

On a related note, when you change your brake lines, replace all the fluid. Do not mix original DOT 3 with a synthetic brake fluid. It has been mentioned the combination of fluids may clog the cyl and lines. This should be done every couple of years anyway since brake fluid attracts moisture. Flush the clutch lines as well. This is easy to do if you have a power brake bleeder. Without this tool you may have a hard time getting the slave cyl bled.


I will stick with the tested Zimmerman rotors and OEM lines.
