you are talking about the radius rod bushings? that go in V on the front crossmember..
i didnt plan anything special, thought about it a few times..
i think that there are already 2-3 companies out there that actually makes Spherical bearing for the radius ros bushings of EF chassis...
check out opmmotorsports
i think they have one..
( they also sell the same "type" of solid bushings that i do..but for 10-15$USD more and they are made out of delrin wich costs 4 times less than my material

)
