Need handling help..

well, you are right, i havnt had it aligned yet since the front end build, but i did align it with a lazer and wheel plates and got it pretty good. It drives straight when letting go of the steering wheel and all but yes, i do need to take it to be aligned on a machine. Does anyone have the 'Better specs' sheet for the alignment that used to be passed around here? I remember seeing this and it said to have them align it to these 'updated' specs rather than what the factory called for back then..I will tell you that when going a little hard into a turn, the front seems to feel like its ok but feels like the back end is what causes it to feel like its going to roll..kinda like when the back end starts following the turn of the front end, it feels floppy..not good at describing stuff..I will tell you i have air shocks on the rear because the rear sags so much.. I need to find new leaf springs badly..any recommendations for the leafs?

It depends on what you want for height in the rear as to which sprAngs you need. A lot of people are happy with the XHD springs. They were stock under the 340 cars.

I'll tell you this too......depending on "how high" you have those air shocks, that can affect caster. If they are too high for example, that will reduce the caster angle. these cars really need all the caster they can get and taking anything away can have a negative effect on how it handles.
