Im not trying to emphasise who came up with it first, just that more research has been done than in this thread, and there are reasons that it is bad practice.
Im not confusing the 2 don't worry.
Due to the new tie rod end angle, when your wheel is centered your tie rod ends now angle inwards (the angle is level to the ground stock)
As you turn wheels your tie rod/ rack length alters.
You can see here, the tie rod end no longer points to the ground at straight ahead.
Now you can imagine/see what happens at full lock either way. Instead of being equal angle both sides, it is now different lock to lock.
It makes the car feel a bit odd, and WONT remove bumpsteer. Nissan spent alot of time getting this stuff dead perfect, to alter a few points and angles really upsets things.
As far as the FLCA, it was the dentsport items that I based them off, I never said they were new. Just easily rebuilt once made.
No use of the stock arm, and they use a 3/4 bolt not a small taper bolt. Ive seen too many fail when the taper was incorrect, or the finish on the material was too coarse.
Def hasn't had issues with the 3/4s so far, and its a similar kit, but witha 7/8 bearing, and youll see the Roll center cones sit in the bearing, removing (reducing significantly) lateral load on the bolt.
