When i go throught right turns, my car starts to get a heavy shake ans it starts to slow my car down alot. I really cant accelerate through the turns. I've replaced tires, wheels are balanced, and its a new brake setup and they are working great but it still has a horrible shake. Please,if anybody has any ideas post them.

 

Have you checked your axles? Did you do a motor swap?

 

Might need alignment. especially toe problem
Too much chamber -- steering wander around
Too much toe -- tires left and right cancel each other foward or rear motion.

 

Really does sound like the axle. If an axle has gone bad this could happen, if this is the case, you should hear a knocking sound when you turn on that side.

 

When you mention "shake", is it shake from jitter (stop and go, jolting) or shake
(left, right, up ,down)
if its the first one, might be that the rotor (disc brake) is not balance, Brake issue, someting not installed correctly.

if its the 2nd shake, sound like the alignment or axle issue.
