I know - it's been covered before - but after serious brake fade incident yesterday and noticing that my disks need replacing anyway - what's the combination? Are the disks the same? what year model for the 9K calipers and what preference on pads - etc etc.

Um mine uses 94 model 9000 calipers. And straight fit disks from the same car (Though brand new ones).

I use stock 9000 pads on the front.... I did run a fancy carbon kevlar compound but they were not really good at low temps....

Excellent link John. It's allowed me to find, rather unsurprisingly, that the 9-3 and the 9-5 have the same disks as the Vectra

Johann,

I think its '89 and on for Aero 9000 and '90 onwards for all others with the bigger calipers. Backing plate needs to be trimmed slightly to get the larger calipers to fit, and you will also need new brake lines as well. This is a good excuse to get some braided ones. 9000 disks are slightly thicker, though 900 ones can still be used, as a new 900 disk is the same as the min regrind thickness for a 9000 one.

Piston diameter is slightly larger than on the 900, giving a fraction more pedal travel.

One slight problem with the 9000 brakes is that the pads are unique, which does limit the range of aftermarket pads. Rear handbraked 900 share front pads with one of the earlier BMW 3 series models.

Um, the Ate calipers on the 88-on 9000T and 90-on 9000 N/A versions do share their footprint with other Ate calipers, and the application list does sound a bit more interesting: BMW E30 M3, Ferrari 328 and Testarossa... That's at least the backside of the box of my Ferodo DS3000 compound says, and probably the reason these are made at all... ;-)
