From what reading I've done on other forums (I'd like to find a real reference on this topic, drilled vs. slotted vs. blank, but no luck so far) blank, plain face rotors are really better for street driving because of pad wear and overall surface area. Drilled, slotted, and combination rotors tend to eat pads. And, cheap drilled rotors have a tendency to crack. I also have read that modern, good quality pads don't have a problem with gases and contaminants that would justify the slots or holes.
Basically, people are saying fancy rotors are purely for aesthetics these days. Not sure where I stand. If formula one cars use blank rotors aren't they good enough for us?

Found this.

Lot of good reference material; not much on slotted vs. blank discs, but enough to assure me it doesn't matter for street use.
Has anyone here had problems with increased front bias after doing the A8/TT upgrade? Anyone done or seen 60-0 distance tests before/after the upgrade?

So your's has that black running down the side of the car too... Was that standard on the white 2.8L cars?
So I noticed on my way to and from work (hour drive, back roads) today that the car doesn't really warm up. Heater works perfectly, the cabin gets nice and warm. I was watching the temp gauge and it never gets much above C. It reaches the 1/6 mark between cold and hot but that's about it. Oil temp gauge doesn't seem to move above the 150 degree minimum.
Is that normal for these cars in 20 degree weather?

Thermostat is stuck. Seems pretty common on the 2.8Ls from the 90's. My sons 96 just did this. Heated up fine if idled in the driveway or driven below 20 mph with the gauge going right up to the mid point on the gauge, but as soon as you get up to 40 mph or more the temp comes right down and sits about a needles width above the C. His thermostat would open at 190 degrees like it was suppossed to but not close until the temperature got back down to about 70 degrees. I had it in a pot of water on the stove and watched it do this. Can't quite figure out how it happens because it was never stuck, and it opened just like it was suppossed to. Anyway a new thermostat cured the issue.
