ha ha ha. very funny about the wiperblades. i hope your not like everyone else ******* the ground kits when you never even tried one on your car.its all about wire resistance man. what conducts better, aluminum ground wire or copper ground wire? check resistance levels on a 200 strand aluminum ground wire and a 2,000 strand copper wire. electricity takes the path of least resistance and when the grounding kit is installed properly, the electricity doesnt have to work as hard to get back to the battery.like i said earlier, not sure about an hp increase(feels like it though), but the motor runs smoother, headlights are brighter, and audio system is cleaner.

 

For the price those batteries better be the best and last a long time. It would cost me $209 for one.

 

ive had mine for 3 years and still goin....

and ya about the grounding kit where did u get yers inthewerks?
