2000 Cadillac Seville SLS from North America - Comments

I just bought a 2000 Cadillac STS. Perfectly smooth on the highway, it came with Goodyear Eagle LS's if this any help.

I've owned 2 olds auroras. I know it isn't a caddy, but it is a close cousin. I've heard of some vibration problems solved on the olds with new front hubs. I can only relate my expirience as follows. both of my olds had the autobahn package (the exact same transmission and differential as the STS). the first one came used with michelin energy MXV4+ V-rated tires. FANTASTIC ride. it was written off 2 years ago. last summer I bought a '98 with goodyear something-or-others and it was horrible. I felt every bump and crack and there was some sort of annoying vague thumping between 100-110 km/h. I went to my favorite tire dealer and had 4 michelins installed and balanced and had a 4 wheel alignment done. FANTASTIC! smooth as silk far above the posted highway speed, although I would never do that on an active road :) i'll warn you that 4 MXV4+, installation, and a 4 wheel alignment ran me $1200CAN, but I hate things that don't work properly. I would also get any modified parts GM has released installed as this would help as well.
