I recently purchased and self fitted a set of Norbitt (after market) front Disks and Saab original Pads (made by TEXTAR!!) for the grand sum of £76 including VAT (but not postage) from Neo Brothers. Norbitt are a Swedish after market manufacturer who specialise in Saab and olvoV parts, etc. Most other price quiotes I had though were in excess of £120 inclusive.
One BB member had a set of Norbit disks warp earlier in the year, but I haven't had this happen (yet!).
A local parts supplier (who is normally very reasonable) quoted me £80 as the cheapest available price for Lucas/Girling disks for the 9000.
By the way, fitting is a fairly easy job and the Haynes manual guidance, as with BillJ's web notes, are sufficient.
Not to be awkward, but I've got the German and Swedish catalogue (June 2002) in front of me (because I'm sad) and they don't do Brembo. They list Zimmermann @£25/ea and budget @£19/ea. Pads are £26 per set.
I must admit to finding the torx headed screw that holds discs on a %*£[email protected]~ to get off, and have had to spend some fun time drilling them off.
As a recommendation I've got soem Textar on my AERO and these seem fine. I got through budget discs in 6 months and found them to be a waste of time & effort.
If anyone wants to be on the safe side, you can get Saab original front disks and pads from the likes of Elk Parts for around £130.
Whilst I went for after market disks, I'ts worth noting that the braking effect significantly improved once the worn original Saab disks & pads were replaced. Undoubtedly as good an improvement would have been noticed if Saab original parts were used. My point being, worn disks with pistons heading towards maximum reach, are evidently less effective than when fitted with new disks and pads - with pistons fully retracted.
Re Torq 40 retention screws on disks. I think BillJ's website suggests going straight in with a Impact Driver, rather than rounding off slots in the first instance with a screwdriver.
I found one or two wacks with an impact driver did the trick nicely without any damage to screw heads (although my car is only 4.5 years old).
