so my car has always sat much lower in the back driver side than the back passenger side. mostly a quarter of an inch. now i think its worse.
car has a road and track box (bilstein hd's, road and track springs, poly bushings everywhere, k member brace, ect.), minus the panhard bar, torque arm, and solid steering shaft. and the rear control arms are extreme duty adjustables.
the front has poly isolators in the springs, and sits a tad lower on the driver side. maybe 1/8th of an inch difference.
the rear, right now measures a quarter inch lower on the driver side, but thats with my adjustable control arms maxed out on the driver side, and bottomed out on the passenger side. if i set them equal, i think its like 3/8s to a half inch difference, ill match them up today and measure.
i've tried measuring on different surfaces and all that too.
now to my knowledge its always done this, and when i had my griggs lower subframes done i had a very reputable mustang shop (Performance Auto Sport in Richmond, VA
) install them. they of course did them on the lift, on its tires.
ive had the rear upper control arm bushings replaced with stock replacements, and im about out of things to do.
i have a friend who's dad has installed many roll cages, and subframe connectors in mustangs. he says the back halves of these cars can sag to one side or the other allot of the time, and that then when my subframes were welded in it of course seized it in that position. he does this in a garage where the floor isn't level, so he says he puts the car on jack stands, measures it all up, make sure the stands have the car completely straight, then he welds them in. he says that this will straighten out the car.
only thing i can think of is that i rear ended someone a while back, and its shifted my front end a little. but its always sat lower. i do plan on fixing the front end also.
so should i get mm full length subframes and have this guy redo my lower subframe connectors? or is it still big no no to weld in subframes when the car is not on its tires?
only other thing i can think of is that the panhard bar will straighten out my rear end from side to side. from what i understand it works like an adjustable track bar on jeeps, it moves the axle to the passenger or driver side. so should i order a phb, and a battery relocate to put it in the back passenger side, and then see where im at?
soon i will level out my rear control arms and measure again.
also, id like to lower the front a little bit, what is the best way to do that, get oem isolators? or can i just pull the bottom iso out, and wrap the bottom of the coil with electrical tape a couple times?
thanks guys, looking forward to a response.
