Ive been searching around for a grounding kit and have found that sean's custom one is good but he only does local and Gordgee's kit is also good. Can i get some feedback on other good kits and where i could buy them.

 

why? they don't do anything.

 

I heard it improves electricals in the car and better for AT also makes the engine bay look nicer and cleaner. I also want to put a grounding kit on my car but no sure what to go for 4awg or 8awg and where can I buy them

 

Yea i figure its the last thing i should do before a tune.
