Not to be harsh, but any of you that think they are getting a good ride or great handling on the stock shocks and neuspeed race springs havn't been on a properly dampened system.
A shock is valved to handle a specific range of ride height, and a specific range of spring rates. Go out of these ranges either direction, and ride quality and handling will suffer.
The stock shocks are valved to handle the stock ride height, and the stock spring rates. You are dropping the car by more than 2", and more than doubling the spring rates. Its not hard to see that the stock shocks can not handle those springs.
Can you physically pair the stock shock with the stock springs? Of cource. But the shock is not going to do its job, which is to properly control the kentic energy of the spring. You will end up with a very bouncey ride (which some might confuse with soft ride, but a properly dampened spring is much more comfortable than a underdampened spring), and eventually blown shocks.
