I read it from Stillen Catalog and it said it will give you 2-4whp gain with G' kit.

One thing people forget... Electricity flows negative to positive, not positive to negative (you can thank Ben Franklin for the latter belief).. so definately crucial is a solid ground from the negative of the battery, (which is why i helped out that stock 8awg off the battery and supplemented it with a 4awg)

 

Don't want to make a new thread, so I'll contribute here. I must say, these grounding kits are FREAKING sweet, wow I feel like I am driving my old M3 with the SMG tranny. Love it!

 

I like the look of the grounding kit but I don't really notice much of a change. I guess my butt dyno is off.

 

Anyone bought the silver one?

how does it look?

 

I notice a huge change from 2-3-4-5 and downwards, however from 1-2 is a little bit on the laggy side.
