Hey all, I've got a leaky tie rod end bushing so I bought myself a new one with bump steer adjustment. Now my question is does it even make sense to adjust bump steer on tie rod end without adjusting ball joint on LCA, or would it actually make things worse?

No that sounds correct, bumpsteer is influenced by the relative angles of the tie rod vs LCA. Roll centre adjustment is a separate issue though.

Sorry it hurt my eyes when I tried reading it.

i've recently put in gktech v3 knuckles front and rear and some hardrace rca tie rod ends. the difference is night and day for a lowered car.

i use my car for grip setup and don't need the custom LCA but if you can afford to spend the money on these mods it will probably be one of the best investment. this is for the s13/180sx chasis.

Thanks, didn't really screw that font intentionally...

Unfortunately Gktech knuckles are for non-abs cars only and I want to keep my abs, but I've booked the car to fit those Gktech tie rod ends - so we'll see how it goes.

I do most of the work on the car myself but in this case biggest part of the job will be alignment so I think I'll let the shop do the whole thing
