I recently rebuilt my brakes with slotted discs in front and stock discs on the rear, with Raybestos QS Ceramics on all corners, plus Earl's stainless steel brake lines. I also was coming from a stock setup so the dust was terrible. I went with the Raybestos mostly on Bill R's recommendation, low dust and long wear. So far I'm happy with the setup. I also rebuilt the front calipers since I figured they needed it. The kit from BMA is cheap, like $3.00 ea. It's really easy to do if you use compressed air to take them apart and then to expand the new inner o-ring to put it back together -it's about impossible to do it without it.
Btw, I also installed a Sachs kit, M5 sways, uppers, lowers, links, adjustable front camber kit along with 17" rims -it's a lot better car imo. You won't regret doing any of those mods.
