Buggy springs front and rear are not exactly known to produce a good handling, nice riding car.....Raising the ride height will also raise the center of gravity on the car and adversely effect the roll center and instant center which will only compound the inherent poor handling of solid axles and buggy springs. Not wanting to build a cookie cutter car is fine, I'm guilty of the same thing.....Remember though that their are a lot of engineering opportunities to deal with in order to have a car that will go comfortably and safely down the road......
