Brake discs ATE or Detroit Axle

ATE powerslots are plated, they dont really rust. the braking surface will eventually, when the plating wears, but the reas of it lasts a long time. I like mine.

I have a Golf 2.0 GL replaced front brakes with ATE rotors and Mintex Reds this time last year.

I have ATE powerdiscs on front and Zimmerman Xdrilled on rear. They both rust. I haven't had any problems yet with warping on either but I installed them about 2-3 monthes ago. I've heard that the Xdrilled can begin cracking around the holes so I'm watching out for this. So far I'm happy with the setup. I also have the mintex redbox pads. Slightly better than OEM and a whole lot less messy. My rims don't collect much dust anymore.

You can change to vented 9.4's; without changing the calipers! Just get vented rotors and the corresponding pads. The rotors are no different. Adirondack does a Mintex Red Box pads/ATE PowerDisc package - 2 rotors & a set of pads, $84.00.
