The installation is complete. I have put a some miles on the car and pushed it only a few times. My initial impression is very positive. The car has quicker turn-in and less body roll when cornering.
In contrast to some of the above posts regarding increased understeer with the stiffer front sway bar I have found that the car exhibits less understeer.
The new springs drop the cart by a little less than 1". So far I am very pleased with this mod.
Pictures to follow in a day or two.
