i have about 400 horse at the crank but i dont have posi. id like to get posi and 4.10's. this will most likely turn the body into a pretzel. will frame ties and traction bars do the trick? or will i have to go threw and do a intense job and remove the torque arm and replace with strong sub frame ties. PLEASE HELP!

 

Get a set of Spohn Sub Frames, have them welded in like In the instructions and you souldn't have any worries. BTW the car is already a pretzel, the difference of subframes is simply amazing, **** that used to rattle and squeek Dosent anymore and it gives you a Great Place to jack the Car up, That alone is enough for me, since getting a Jack Under the car to a solid area to jack is a PITA. Most shops Will charge about $50 a Hour to install, If you remove your carpet Wire brush the Floor boards where the Welding Will be done, It shouldn't take more than 2 hours at the most, Just be sure to by Some Arersol Undercoat and coat all Welds after they are done.

Just my

 

i added subframes and made a world of difference. ran for a year with the bottle at roughly 300 to the wheels and i startd to crack the roof where paint was actually chipping. added a cage with my motor swap and everything stopped after the repaint. i wouldn't suggest going that route though until you have to.

 

Get an aftermarket Torque Arm. The torque arm has nothing to do with the body twisting, but if your making that much power to be concerned with body flex, you need to take that same stress off the tailhousing of the transmission, as they will break.

BTW, most hard top cars crack in the corners, even with stock engines.

 

Yup. Mine was cracked when i got the car and it had a v6 in it.
