I can't agree with that 100%, they're effective with "good enough" OEM mounts. Sure if they're original B13 mounts or in really tough shape, then its not gonna do shit. But if the car's seen a set of new ones in the last 20 years since new, it may suit his needs. I used inserts on 7-8 year old mounts on my U13 and that really improved the precision of the shifting The OEM were in good shape, and that's only a DD, it worked well. Speaking of shifting, the rear linkage shift mount bushing IMHO is a must have.
But +1 on not solid mounts F or R, man that makes me feel like one of those 1970's beds in a cheap motel - where did I put that quarter?
