Default voltage stabilizer and grounding kit?

I have a 13 Impreza 2.0l. I have installed a grounding kit before and on an older vehicle it made a difference. I was wondering if a grounding kit would make any difference or if any one used a voltage stabilizer on a newer car.

It's meant to provide a better ground for the electronics. A lot of modern cars don't have adequate grounding given all of the electronics in the car. If you have insufficient grounds, the voltage doesn't flow as smooth as it should causing delay in commands and other issues.

However, while the theory may be sound, I haven't seen any proven results beyond the butt dyno. Some people swear by them, others say don't waste the money, but one thing that is usually consistent is the car those people are driving. The people that swear by them all have car X and those who call them a waste have car Y. I've thought about putting them on other vehicles I've had simply because they're not expensive and they couldn't make it worse I suppose but I never purchased one.

I'd be interested to see if these cars are any different after having one installed.

Thanks.
I may just buy a spool of 10ga wire and some eyelets and make my own. I have done it before and seems to smoothen out idle.
Will post results after I do it.

Try turning on every possible electrical load (headlights, wipers, A/C, rear defrost, both heated seats on HI, blower on 4, fogs, etc), then measure the voltage between each of these to see if there is a weakness:

Chassis
Block
Negative battery terminal

Ideally, the voltage will be zero.
