Go to this link for instructions on installing body mounts.
I used solid aluminum and there is no discernable ride harshness. I didn't change anything else at the time, just the bushings. The steering feels more solid.
Just FYI, I've done some more updates since then. A quick test drive (haven't done a full alignment yet) showed even with: Hotchkis 1.25" antiroll bar, del-a-lum style control arm bushings, GR2 shocks, 245/45R17 and factory coil springs the ride is still very nice.
I think the stock springs, mild shocks, and "zero-friction" arm bushings make all the difference in keeping a nice compliant ride with good handling.
