In addition to the great improvement in geometry, the ATS spindles offer numerous bolt on brake systems. Everything from stock C5, Z51, C6 Z06, or any aftermarket C5/C6 system will bolt right on.
I would say that adding the ATS spindles made as much difference in the drivability as adding the LSx engine.

Great car Andrew!!!! I been following this thread for awhile and I just finished thumbing through the Run Through The Hills IV pics. I was hoping you had more information about this 70' Chevelle pictured. I 
have one and would like to copy some pieces of the car.

I can't really comment as to how the ATS spindles compare to stock, because my car hasn't been stock in a VERY long time. I can tell you that it is a completely different experience driving the car with the ATS spindles compared to the b-body spindles that I had before. The bump steer is totally gone and the car tracks straight as an arrow even on roads that are bumpy. With the b-body spindles the car would dart around when one wheel would hit a bump and the other one didn't. It was a little unnerving.

I took the car to the track this Saturday. The weather was awesome. Clear skies, dry, and high 60s. I only made 3 passes because my time was limited and there were a ton of people at the track. All passes were made without fooling around with tire pressure or shock settings. Drove it right off the street, into the staging lanes. My first pass netted the best MPH to date; 112.31 MPH. The second pass netted a my best ET to date:
60' 2.064
1/4 12.602
MPH 110.97
This is my last trip to the track for this year and I am very pleased.

So I gave Autometer a call to see what words of wisdom they may have for me. Basically they told me that they have been unsuccessful in making their tachometers work with the low voltage signal that comes off late model ECU output wires. Their suggestion was to purchase the 9117 box that taps directly into the coil harness and converts the signal (whatever that means) to a square wave that can be read by the tach. My initial reaction is that this is BS, to get me to buy an $80 dollar box that costs them 5 bucks (at most) to make. I am going back to Radio Shack for a collection of 99 cent resistors.
This brings up another point. Why couldn't the GM engineer who worked on the GMPP harness pick up the phone and dial up Autometer, VDO, and Stewart Warner? Between those 3 brands I bet you will cover 95% of the aftermarket gauge market. It would have been a 15 minute discussion to determine what these tachometers need in order to function properly. The information could have been easily outline in the harness instructions. Instead, they put this in the documentation of the harness:
"Note the signal is a low voltage square wave, some older style of tachometers may need a pull-up resistor in order to read the signal -- this detail is left to the user"
WTF?!?!?!
