Rear Suspention questions

Ok The stock bushing and springs and struts are trashed. So I Wanted to get a few idea's before buying a kit or parts. I have done some reading and what Im trying to accomplish here is.... DOT's Tires not spinng at 5k launch then hook and the nose not droping 10 foot past the line and start breaking the back tires loose and the car steering itself on the long side of the track. lol i needs help it does everything its not suposed to.

I think Im going to do the eibach drag springs for the rear, southside bars or traction bars that are close to equal. adjustable uppers so I can dial them in at the track and all poly bushings. not sure on the struts yet. also got my buddie fabing up some sub frame conectors and beefing up the battle boxes. also it is a vert.

for the front I was going to leave stock springs and go with some lakewoods coil overs adjustable and the billet mount on top

I am also goin to do my inner tie rods and have it aligned but I think Its the rear steering on me at high speeds and the front end bouncing up and down.

please some construtive critisim would be awesome, trying to slow up the rebound ratein the front and stop the ass from dropping off the line

found some lca's

Found some, southside LCA's I read up about how they kill the battle boxes because the dont have any poly in the bushings?

has anyone had these problems?
or beefed up the battle boxs good enough?

My buddie is a welder/Fabricator who is also into Foxbodys, He thinks we can reinfoce them good enough.

also Most of the time it will be on street tires, I need a set of rims to mount my M/T Dot slicks for those weekend night street runs.
