if you have a lot of bumps and potholes, then you don't want to make any of the bushings that provide for/aft support(tension rods, traction rods, etc.) too stiff. for those, use urethane bushings.
replace the bushings that provide up/down support(rucas, rear toe rods, upper strut mounts, etc.) with spherical bearings.
in all cases these are good.
-Nismo power brace
-strut tower braces
-trunk brace
-fender brraces
good luck.
