Rear Upper & Lower Control Arms

Do not change the uppers if you go with poly bushing lowers.
It will eat the bushing alive.
Especially if you do any open tracking.

You can get away with it with a Pan-hard bar sometimes.

Keep your eyes on the bushings at the chassis end.

On the one Stang I went cheap on I ate bushings often.

After speaking to MM, Steeda, BBK and several others they all said the same thing.
Stock uppers are the best unless it is a Drag only car.
The big stock rubber bushings help keep The lowers from binding.

Replacement bushing are cheap. lol

PITA is changing them though.

Have you ever read this?
