why are the strut towers bad gounding points? They are an integral part of the vehicles chassis.....which is what you are supposed to run electrical grounds to, the chassis, not the body, although the WRX is a unibody type vehicle which translates into the chassis and the body being pretty much the same piece, for the most part. I am not trying to start a flame war here, I am seriously curious, maybe you know something I dont, and knowledge is power.....so please correct me if I am wrong.

AHHHHHHHHHHHH, I see, that makes sense.....
I guess I'll be moving my DIY grounds then....LOL
Thanks Kman*

ALSO.....
Bad ground point...think about it....the stud is set in rubber in the strut top, the body is painted, so the only place where there is any electrical contact is where the threads touch the sheetmetal ring that the edge of the hole in the strut tower top. Even if the stud touched any metal in the strut top, current would have to pass through the strut components to get to ground(the body).
Better to use a bolt which is held to the body by a 'captive nut'. A captive nut is a nut welded to the body on the back side so that you don't have to hold it with a wrench to tighten the bolt to it.
I think this is one of the main reasons some people see no improvement when doing the grounding mod. They used strut top studs which are bad grounding points.
AND FYI
"HKS has never claimed actual horsepower or torque gains from adding our HKS Circle Earth System grounding kit.
The person's post is correct assuming that the vehicle is operating at ideal and its most efficient standards. This means that the electronics controlling engine management for fuel injected vehicles are running at maximum effeicency and fuel is ignited completely.
In order for electronics to run as efficiently as possible, there must be as less resistance in wiring circuitry as possible. For all circuits, there must be a point of reference called a ground or earth,
which describes a "zero point" or a "fixed point" in which all things (related to electronic components) can be related to. Descriptions are relative and can only be descibed in relation to something that is fixed.
In this case, grounds are defnined as a fixed zero volt and zero current. In most cases, these grounding points inside the engine bay start to deteriorate due to oxidation (rust) with the electrodes and to the body of the vehicle. Wires start to become brittle and less ductile from engine vibration and heat. The materials that wires are made of start to lose there electromagnetic properties, therefore losing efficiency. Some of us know that the manufacturers of some vehicles in relation to its electronics is weaker in some cars than others. The older the car, the less efficient. ETC.
There are many variables that can lead to electronic signal inefficiencies. One type of alleviation to such is creating a more solid ground to electronic components by adding an aftermarket groudning kit such as our HKS Circle Earth System.
Here is an example. For older rotaries, mostly turbo models. Sometimes rotary engines bog at approximately 3500rpm, in which the secondary injectors start to fire. This is sometimes due to an incomplete/bad ground on the stock pressure sensor. By cleaning the ground wire electrode and sanding off some paint on the body where the ground wire electrode is attached, the bog lessens or dissapears. Some people actually rewire the ground wire using newer, thicker gauge wire. For myself, I have done the above and added an extra ground using our HKS kit.
The 12/24 Volt Tuners (stereo/sound fanatics) have been practicing such additions of grounds for a long time, to increase their stereo's potentials and sound quality.
This is as close as I can get to explain why grouding kits can be good for engine efficiency without getting too complex with equations and actual scientific theories. If you want to further research more explantions on this subject, I suggest that you go to the library or a technical book store and pick up a text book on electrostatics.
BTW, just because we do not reply on this forum, it doesn't mean that we don't defend our product. This is a voluntary forum. Sometimes when topics like these accuse us of such negativity (and reply with such sarcasm), we have to be careful on what we say therefore take longer to respond. Sometimes, it is a moot subject and we don't want to respond.
AND there is nothing wrong with a "BLING" factor because most people who I have talked to think it looks cool and well worth the money for its applicability and the highest quality materials used to make this product."
