Go to you local car audio dealer buy the cables, connectors, etc... and build it yourself.
The performance gain isn't huge by any means 9barely noticable) not worth a $150+ kit, but for $25 worh of parts its worth it.

You can find diagrams for hook-up on this board by searching.

This will give you an Idea from the Daizen kit.

I would probably save a little more and get the HyperVoltage Kit from Sun. You can make your own grounding wires from Monster Cable, though I do have both the HyperVoltage and HyperGround systems on my RX300. The HyperVoltage system is way more noticeable than the Hyperground (ran a few tests).

I have pictures of my setup on http://www.cardomain.com/ride/2215309/5

For performance, I can notice a much sharper throttle response, no lag.

Contact points should be engine block, transmission, body, alternator, throttle body (though the latter two were tough in my vehicle).

"The HyperVoltage system is way more noticeable than the Hyperground (ran a few tests)"

Please explain this "(ran a few tests)"
What tests?

And this "The HyperVoltage system is way more noticeable than the Hyperground"
Define "way more noticeable".
Sorry I just don't get it.

These systems provide a minimal improvement at best, How are you noticing such a difference?
I could possibly see a big difference from old, stock insufficient wiring to a kit but not a big difference from kit to kit...

What I did was first use the Hypervoltage kit by itself and take it on a flat stretch of highway near my uncle's place. The pickup and torque was noticeable than without this device.

Then I tried just the Hyperground kit (with the hypervoltage) and I could feel some difference, but nothing like when the Hypervoltage was attached. Slight improvement in torque, throttle response.

When I put both of them together, it was a tad more noticeable than with just the hypervoltage system.

On the track (1/4 mile), I used to run 2.8 60 foots and with this system, I can hit 2.7s more easily.

WHAT WOULD I RECOMMEND?

Before you thrown down your hard earned $$$, get an Optima battery, cheaper than both if you get it at a place like Costco.

My only reason for getting the HyperVoltage and HyperGround was that I wanted to add as many modifications as possible to my RX300 (and unlike the GS series, we virtually no aftermarket performance products).

i just installed my homemade grounding kit, other than the fact that 8ga cable looks nice all over your car, i did not feel a diffrence in performance. glad i did not pay retail. i did notice the idle get a little better, but that could be all in my head.
thanks gilllexus that pic help out

To make sure all your efforts are not wasted, make sure all the wires are actually grounded. I noticed that the 2 wires I hade going to the inside fire wall were bolted w/ a bolt but when I checked the other end that connected to the fender it was not gounded.
I Used a test light connected to the battery and touched the ends of the ground wires.

Also make sure that your wires are connected to a "true" ground, the paint must be removed at the cnnection point oherwise it will be a poor ground.
As I said it is not a huge difference.
