I understand this is a common problem with the 1st generation LS. Especially 90-92. I was wondering if the rotors of a 94 LS would fit on a 91 LS? I've
changed all 44 rotor on my wifes 91 LS and the vibration stopped for about 5 months. I know I'm not the only one with the problem. Please help. I have already had the rotors resurfaced which lasted another 5-6 months. Now it's starting again. HELP

 

you can use the rotors from a 93-97 Toyota Supra I believe or you can contact Steve Ganz from Carson Toyota and see what he suggests? Tell him you are from Clublexus.

Are you using stock Lexus pads or aftermarket pads?

I found that the aftermarket pads would start vibrating within 2-3k miles. They stock pads didn't have the same problem, but I would go through a set in 10-12k miles.
