When I put the Zimmermans (purported to be among the best as they are cast with the holes rather than drilled after the fact) on my '92 9000T I really wanted them to be the shiz-zat. I mean hell, I paid extra for them and they looked extra-spiffinatious through the SPG style wheels. But I came to realize that (at least in my application) they were all show and no go. They were *much* noisier and I could not acertain any improvement in stopping distance. Then after only ~5-6k miles they started to warp. Ugh... I took them off at that point and had them turned (against better judgement) and they lasted another 5-6 k miles until I eventually sold the car. Maybe it was my choice of pads with the disks that caused my dissatisfaction (actually had 2 different sets in that measley 10k miles, Pagids and PBRs) but I was... well, underwhelmed. -- -Fred W
