Have anyone try out the Hyper Ground System and the Hyper Voltage System from Sun Auto yet? I heard that the two systems work really good with the RX7 but i have not heard anything about the RX8. If anyone have try these two part before, can you let me know how good it is and if it is worth the money.

 

I've installed the Hyper Ground System and it smoothes out power delivery, noticably reducing the surge around 7K. The car also seems to go through the revs slightly faster. I've yet to install the ground wires but I plan to in the near future.

 

is it hard to install, how long did it take u

 

Two wires that connect to the battery terminals. takes about 15 minutes.
