rear suspension help

[Killasbc]

for start this is the suspension set up in the rear.....metco double adj uppers, single adj lowers...stock springs..ARB...and QA1 single adj shocks.. everything is Spherical/heim joints

i had a th350 in the car and was foot braking the car at 1,800rpms with 29x11.5 qtp hoosiers, 3.5 degrees of neg pinion angle and the car worked great at a 1.39 .60 foot

i blew the transmission up and decided to put a power glide in it with a trans brake(leaving @4,300)..since the first gear is soo low i also changed the rear tires to a 28x11.5 qtp hoosier ( with doing so my lower control arm angle went from +3 degrees to +5 degrees) and i took some pinion angle out and is now at -1 degrees the car is now every inconsistent and the best .60 ive gotten was 1.49....any ideas?? i need some help

Hello
Seeing how you are leaving at 2500 more RPM's I would suggest you have a little more fine tuning with the suspension now such as adjusting the rear shocks and make them a little more softer to hold the weight when the weight transfers seeing how you are running a drag radial. But if you are running a slick I would suggest a little more firmer and let the sidewall of the slick come into play. Because leaving on the foot brake and trans are completely different animals. And in that case it effects your weight transfer throughout the whole entire vehicle.
Hope that can help!
Thanks
Brad

its not a drag radial...it pretty much a slick wit 2 lines in it like the m/t et streets...iknow they make brackets to bolt onto the rear to change the lower control arm angle but do they make any kind of brackets to bolt into the front of the lower control arm bracket to take angle out of the lower control arm?
