We all know that the steering wheel turns the wheels and the rest car follows (or leads if you over cook the entry). But what many neglect is that all driver input into the wheel have to move through an entire system of pumps, pulleys and arms before the wheel actually turns. Most of the system is unable to be changed because of the cost and difficulty of chaning most of the components. One thing that can be changed is the tie rods. The tie rod (inner and outer) are the two peice arm is what actually turns the wheel itself (via the spindle). But because of the small diameter of the rod and the age of the parts, many times the original rods are bent or worn out. Also, the thin rod is easily bent at the track, so an upgrade will regain steering feel as well as make the system more durable. I chose the units from Tein (Techincal Innovation). Following is a comparison to the original unit (Tein on top, stock on bottom)

The traction control arm/rods (which will be referred to as t/c rod(s) as that is the common name used) are the arms that attach the lower control arm of the suspension to the front of the car. Stock units use a gel filled bushing that leaks after about five years. Being that the units on my car were closer to 15, they were due for a change. Replaced with (now discontinued) Project Silvia units utilizing a spherical bearing as opposed to a bushing, the new arms are adjustable (allow change is toe angle of front wheels) and add a whole new dimension to steering feel and feedback. The wheels no longer wobble about on a blown goo bushing! In the following photo, they are the blue arms behind the brake rotor.
