The first pic is an aftermarket Tein t/c rod. That is in my humble opinion a premium piece made of steel and carbon steel. No aluminum. Very good stuff.The second pic is the rear lower control arm (lca). Stock piece. It connects the chassis to the lower balljoint/wheel spindle. The sway bar is connected to the lca somewhere near the middle.The last pic would be the rear upper control arm (ruca), stock piece. It's function is to secure the upper portion of the spindle. The bolt that connects this arm to the chassis should have an eccentric washer that can be used to adjust camber in the neighborhood of about 2 full degrees.

Man you always come through for my gumby thanks so does the tein bar do anything for my suspension and could you tell from the pics if I have coilovers or just a shock and strut in the back? I know I don't have coilovers in the front but there adjustable at the top and the guy who sold the car to me said it had coilovers so im not sure if he just meant the back did?

How can I esplain....okay, the t/c rods main function is to prevent or minimize front to back movement of the spindle/wheel. The overall length of the t/c rod affects castor. Usually while encountering speed bumps for example, the stock rod with goo filled bushing will deflect and the tires will be pushed back a li'l bit. The same thing also happens when turning to a certain extent. It is not really noticeable the difference this part makes unless you have driven on the stock, worn out part and then you upgrade to a solid connection. Unless of course you are driving around with a worn, torn up bushing, then the deflection is very noticeable, thudding noises from the front end, shaking and a generally unbalanced feel from the front end.As for the coilovers, I have seen older sets of GAB's that look very similar to what you have to include the position of the adjustment knobs. Unfortunately though, the GAB replacement shocks is what you appear to have. They are very similar to the KYB AGX's in appearance to include the red color. The only way to know for certain is to remove the wheel and see if the shock housings are threaded where the springs mount up. Which I doubt is the case.
