I need to replace my rear suspension and i already have a set of shocks for a 5.0 but i need the rear springs and can get a good price on new stock 5.0 rear springs. Would have the 5.0 stuff on affect the weight dist. and handling since the 2.3 is lighter? If anyone has put them on a 2.3, what is the handling ride quality like?
 
thers no differents in the rear springs except maybe rating,but up front the struts[like nomuffler said are differnt]are more stiffer do to the shock rating of the v-8 verses i4.i did a 5 lug conversion pro stars with 15-8 in rear and 15-3.5 in front and even if i hit a small dip in the road my car hits hard and stiff.there seems not be enough weigh in the front to make the strut move enough to take the shock.also i still have the stock 4-cylinder springs.dunno going back to 4 lug.
 
as far as i know 5.o springs have a higher spring rate the 5.0 guys use the 4 cylinder springs for drag racing because its a lower rate giving better weight transfer
 
my guess would be the 5.0L springs have a higher rating because the amount of torque a 302 creates compared to a 2.3l is substantial. What I am saying is that the front end lifts more when launching with more torque, placing more weight/force on the rear wheels...wich would require a stiffer rear spring to plant the rear wheels properly.
 
The 84-93 GT springs are the same as the M-5300-B springs. When I bought my M-5300-B springs for my 86 Lx it even came with a sheet of paper that gave '85 Mustang GT part numbers for replacement springs.

My 86 LX stock had 365 lb. in. front springs and 200lb. in. rear springs.

The GT had 425-530lb. in. variable rate front springs and 200-300lb variable rate rear springs.

So yes 84-later GT rear springs should be better for the rear.

Do tc springs and shocks work in a mustang also?

EDIT:

It seems the Tbird springs are almost the same rate and length as the SN95 springs. To put SN95 springs in a Fox Mustang I thought you had to cut them but for the Birds the SN95 springs seem to be a drop in replacement.

So yes they will probably fit but they may be too tall and too stiff since Birds weigh more in the rear.
