Stiffer steering rack bushings are good stuff; I have solid aluminum ones in my Mustang. It makes the steering feel crisper since you're not losing some of your steering motion to rubber deflection. Just do some research and make sure there aren't possible issues that can arise out of it; in Mustangs there are sometimes problems in doing Al. rack bushings thanks to Ford's sloppy production tolerances. The two flat mounting surfaces on the k-member that the rack mounts to can be slightly out of plane, so when you go and torque the rack down solidly to these two out of plane surfaces, it bends the rack housing slightly - thus resulting in the rack sticking and slipping inside the housing where it's in contact when you turn the wheel. Just FYI, I don't know how good FHI/Subaru's production tolerances are...
