I agree with you there Trooper but he's already got the money into the electric, if it's a simple fix mites-well use it.

There is a reason for that...the front roll couple of the stock sway bar and stock spring rate is quite low, with the stiffer after market springs your wheel rate went up even though the sway bar was disconnected....add to this that the center of gravity is now closer to the roll center of the car effectively shortening the moment arm against the roll center, your car will naturally roll less....it's simple geometry. It probably handles as good as you need it to for what you are doing....which is perfect in this case.
(Look back a few pages for a dissertation on roll couple)
Like I said, it's a trade off. It would certainly be much faster through the corners with the sway bar....but in this case, we've traded corner speed for....what, a few pounds right?
If you like it....then it's a good trade.

Just for the record... it's a 26.5 lb weight reduction when removing the front swaybar and installing the swaybar-delete kit. I didn't do it to gain any time in the 1/4-mile, but it offsets the added weight of the turbine and intercooler almost perfectly!

Nah... you need springs. 
Actually, I need a swaybar less since I have lowered springs.
All kidding aside, my car sways MUCH less through hard turns with my Steeda springs and no front swaybar, than it did with the factory springs and front swaybar installed.
Daily driver = absolutely no need for a swaybar.
Road racing = definitely need a swaybar.
You'll never SWAY me on this topic!

Here you go....
(Quoted from my discussion with Leo)
Lots of drag racers disconnect the front sway bar for weight transfer...and thats okay, but you sacrifice cornering ability.
Back in the day there were some racers on oval tracks doing away with the front sway bar too....mostly dirt track cars but some asphalt boys subscribed to this method as well. You can do it but you have to return the wheel rate to it's original value so that the car feels the same in a turn.
First solve for wheel rate:
Spring rate X motion ratio (D1/D2) then solve for the anti roll bar rate at it's attachment point-(solve for it's motion ratio) X bar rate and then add to get the the total wheel rate. This is known as "Roll Couple".
Now increase the spring rate to bring the total wheel rate (with out the sway bar) up to the same wheel rate it had with the sway bar and it will have a similar corner response to a car with the sway bar still connected.
The down side is that with the increased wheel rate the tires will run hotter under all conditions instead of just hotter during cornering.....which is why that method was sh*t canned back in the stone age.
My suggestion is:
Leave the sway bar on....disconnect one link at the track....drag race.....hook it back up...drive home.
Best of both worlds.

I think so too, I mean its the only thing I can think of. The gauge did work before they rewired everything. I wonder how hard it would be to find this wire and fix it myself...
