I see what you're getting at. But the body mounts should probably be adjusted or repaired if the control arms need to be different lengths to sit the rearend square. A little error is good, but they should be very close. If the arms are unequal, there will be all sorts of bias in the launch.

Solid suspension bushings are great, but wouldn't you agree that extra reinforcements need to be made to the body mounts (torque boxes)? Beyond what a urethane bushing needs anyway.

In all of the mustangs i have set the suspension up on...none have ever sat exactly square in the car.it only takes a minimal amount to get the rearend to be centered in the car which is where you want it.

It may not sound right but come over to my house and get up under the car with me and i will show you in person

as for bushings...yes some torque box reinforcements are needed.especially on a car running the times that this car is running.I would recommend installing some battle boxes on the uppers and lowers before ripping them out.....because once you tear them up real bad its a bitch to fix.

so in order...

get battle boxes
get solid bushings for the axlehousing and the upper and lower control arms
get an anti roll bar

put it all in and get the suspension set up....and it should 60' in the 1.3-1.4 range on slicks

Yep that is true. Due to production tolerances all mustang rearends sit more to one side vs being perfectly lined up.

How "close" you guys consider it to be perfectly square? And where are you measuring your squareness from?

I've seen rearends in cars off up to 1/4 or 3/8 inch shifted to one side of the car or the other....it makes a big difference.

with all things being the same under the car i take my measurements from the frame rails and get a centered measurement from there
