Good question Jody... I would like to know the same as it looks that I will be doing more of this type of set-up. Here is a pic of our Impala project. I can speak from experience on the ride quality. This car was built a) on a rigid full frame "race car" type chassis and b) is a heavy beast especially with the BB in front and it rides like nothing I have had before. Its very responsive and corners like no BIG car I've seen. I am accustomed to the "old skool" pro-street type chassis with a stiff ride quality and this was a treat to drive.
But in the same light as you, this car will see track time and I (coming from a racing background) would like to know how it will relate to weight transfer and reaction from preloading the rear.
