Black XD Brake
 

I've installed a handful of rotors on light duty race cars and regular cars over the years, ranging from hi-performance slotted to cheapo budget no-name rotors. I'm no pro mechanic, just an avid auto-crosser and DIY'er, but I think these are the best bang for the buck. If anything, avoid the no-name stuff or serious budget stuff. They rust like crazy, and do not have a consistent enough run-out which may lead to brake judder. These come from a respected company and for long lasting corrosion protection Black XD Brake kit paired with kevlar or LUK Schaffer carbon brake pads is definitely the way to go for your Saab.
