Are grounding kits worth buying for the SRT-4?

Ever since I first read about them, I have been skeptical. I'm rather curious as to whether or not they make any sort of noticeable difference.

 

Ever notice when you go to put your windows up how the lights dim? These cars arent grounded well at all. Take a look at the size of the wire right above the TPS, and the one right behind the crankcase near the emissions line. Tiny. Very tiny.

Now are grounding kits really worth it? Hmmm well it could go either way. I bought some 4 ga. wire, and I'm going to swap the dinky wires out for the 4 ga. Theres a BUNCH of grounds in the car, but I'm just going to hit the ones in the engine bay. The 4 ga. will help out nicely. And its cheaper this way.

 

grounding system and voltage system made a pretty good differance on my car.
