Hi,
I need to replace the front brake rotors for my 1990 90 quattro 20v sedan...Just wondering what other audi/vw models front brake rotors will fit my quattro...I'm on a budget, looking for the best deal out there, any suggestions on inexpensive sources for front rotors? Any info is greatly appreciated...Thanks!

Re: Front brake rotors to fit my 90 90q20v? (CoroccoQuattro)

If you have the 10" front brakes, as most of these cars do, these are unique to the 20v sedan. I went through this recently. Rotors are over $100 each and hard to find. They are NOT the same as the 10v 80 and 90. I finally broke down and upgraded to the 11" brakes...calipers, rotors and pads. They come on quite a few models including the 5-cylinder S4 and S6, as well as the 90 V6. The downside is no more 14" wheels...they won't clear the brakes.

Definetely do the 11" upgrade. Usually calipers, pads, and rotors costs about the same as just the rotors for the 10.1" brakes you find on the 90q 20v.
You need a set of the Girling 60 dual-piston calipers (any dual-piston Audi caliper from 1985 to 1997), the 90q 20v sport rotors: 893 615 301 (no suffix) and a set of pads to match whatever car donated the calipers. Usually the calipers run $100 a pair used, the pads are about $50, and the rotors average $100 a pair for aftermarket ones. Compare to Germanautoparts.com's price - $137 each for 90q 20v rotors.

Re: Front brake rotors to fit my 90 90q20v? (billzcat1)

billzcat1 is right on, including his rotor part number...the factory pad number is 895 698 151 and the caliper part numbers are 895 615 123A/124A ...I heard from someone who felt that the roughly $100 he spent for Porterfield pads was very well spent. I ended up with Pagids or Jurids or...something not called Porterfield...and I don't like them...no bite at all when cold/wet.
