My FJ came loaded with after-market parts, including a lift kit and modified suspension. Unfortunately, it's got a weird vibration going on at high speeds. Anyone know of a good shop in San Diego that they've used for their 4X suspension needs that would have smart guys who could likely debug my problem? It's nothing obvious. TIA.

As others have posted, vibration is usually a tire balance problem. Wheel balance is resonant - it occurs in a relatively narrow speed band, say 52-58 mph, or 45-49 mph, etc., and at higher and lower speeds it goes away.
If you are experiencing vibration at all speeds, or vibration that increases with speed, and you have a manual trans, you might have a driveshaft issue...
I'd suggest checking the tire balance issue first (or at least rotate them and see if the problem goes away...).
