I recently replaced my brake pads on my 94 ls400. I used the ceramic pads from car quest. They are much better than the ones that were on there previously. These are very quiet, give off much less brake dust, and have a very good feel when stopping. The only thing I dont like is the metal part of the pads are bright blue and you can see part of this through the rims. I paid about $85 for the front pads. If you are concerned about the look, you could paint the metal part before installing them.
regards,
Jeremy
