ive been browsing a few websites looking at suspension parts namely 50resto and the list different parts for xx-89 and 90-93. whats the difference between them. the reason i ask is if i plan on upgrading to different spindles or changing other things out i wanna know how its going to effect the parts that i need to order in the future.
Difference between 89 and 90-93
- Thread starter The AntiRice
- Start date
ok heres an example if you go on 50resto and look up some of the maximum motorsport suspension kits they have stuff listed in two categories 87-89 and then 90-93. so whats the difference between the two sets of years? what did they do different on one set that would make parts not work for it?
That would be to allow for the different apron design that allowed bigger tires and wheels to fit on the later cars. Other than that, the suspension is the same from 87-93.
Yeah, 79-83 is one style caster/camber plate. Then 84-89. Then 90-93. I haven't looked at the difference between 84-89 and 90-93...but I know the 79-83 and the 84-89 has one stud set further back. I ran into this on Project 81 Hack Job while building the front suspension.

Wasn't the new apron design introduced in 91 along with the pony wheels? I've got a 1990 coupe and always thought I had the smaller wheel wells as anything larger than a 225 tire seems to rub when the wheel is turned fully.

From the "Mustang 5.0 Technical Reference and Handbook" the suspension changes are as follows:
"To increase wheel caster (and improve steering geometry during suspension compression), the tops of the front struts were relocated rearward, slightly closer to the cowl in the 1990 model. This improves cornering (by reducing understeer) and may also have a positive effect on tire wear. The K-frames's lower control arm pickup points were again repositioned to increase caster and improve both cornering ability and tire wear by reducing understeer. These revisions to the lower control arms' pivot points in the 1990 and later K frames adds caster when the control arm is compressed (during cornering and/or braking). Raising the front arms' inner pivots also effectively lowers the car's front roll center."
