I've already have 4 points grounding for my 96 civic, do I still need to Voltage Stabilizer? Does Voltage Stabilizer gonna do anything to my car in this case?

Any one has experience? thanks.....

 

well i did not feel any difference on the car after removing the voltage stabilizer

 

but after I added the 4 points grouding wires, the rpm stay much more stable, and all the lights are more stable....it does helps... but I just don't know if I still need the stabilizer in this case, does it gonna help more???

Anyone get any idea??
