Brake Pads
Any suggestions for pads for my 1993 90cs? For fairly normal driving I have been told not to go with anything too fancy. I need a rear caliper so I thought this would be a good time for an upgrade. Would the Quattro Discs and Calipers fit? Is it worth it? How about slotted or cross drilled. Since this is just for the rear only I thought I might just go with stock. Hopfully my front brakes will go out soon and give me an excuse to have some real fun.

Re: Brake Pads
ATE Power Discs are great rotors, and they look cool behind your wheels, too. Zygmunt carries these, and stock as well as higher performance pads, too. As far as the quattro stuff fitting, I've no idea, someone else can field that one.<ul><li><a href="http://cyber.virtualrep.com/zygmunt/store.tpl">Zygmunt motors</a></li></ul>

Re: Brake Pads
Upgrading the rear calipers is not required. OEM will work fine. Your rear brakes only contribute about 30% of the braking effort on the car. Upgrading the rear calipers is a waste of money, unless you've seriously upgraded the fronts. Even then the rears offer more braking effort than you will ever need! Thats why the rear disk's are unventilated, single disk, and the pads are smaller than the fronts.
I have a set of larger-stronger "race brakes" on the front of my 93 90, and I still run the OEM rear brakes.
The Quattro rear caliper is identical to your current one.
You could get a set of better pads, but not up grading the fronts, while doing only the rears, is going backwards on how you should upgrade brakes.
Installing a set of "performance pads" should always be done on all 4 wheels at once. Or the fronts first. Making the rear brakes more effective, over the fronts, is not a good thing.
Especially with an anti-lock system and street driven car.
For Race setup, one can make the rear brakes more effective, but this is normally accomplished hydraulically, with a brake bias adjustment.

IMHO (and the flames will no doubt come), slotted/drilled rotors only enhance the image of the car. The alleged increase in performance is nothing without the proper brake pads.
The brakes on my CGT are all factory stock (same system as 80/90). The only improvement I made for track days (the brakes would get too hot and the pads would give up) was to replace the stock pads with Hawk Blues. This was an incredible difference and only cost $100 or so. I have had no need to do any further improvements (I also upgraded to 16" wheel/tire combo). Grassroots recently did a very good article on brakes in the last six months I'd recommend you read.
Hawk pads are not really for street use, I'd probably recommend Axis Metal pads for good all-round use.

Re: Ditto Miktip
I use Hawks HPS or HPS Plus as a street compound pad, on my front Wilwood / Brembo setup.<ul><li><a href="http://www.racerpartswholesale.com/hawk1.htm">http://www.racerpartswholesale.com/hawk1.htm</a</li></ul>

here's another web site who sells ATE Power Disc rotors and Zimmermann "cross-drilled"...as for pads
I'd go with Mintex Red Box pads, which this place sells -- it's just not on their web site.
I agree with miktip and Dwight. You should increase performance with the front first then the rear. Or, all 4 at once.
My combo currently: Zimmermann and stock pads until they wear out and then I'm going to use the Red Box pads.<ul><li><a href="http://www.germanautoparts.com/">http://www.germanautoparts.com/</a</li></ul>
