As many of you know i've had my fair share of handling woes.
Here's my stock Mustang lower arm
inner urethane bushes after less than 1000 miles....

It turns out the lower arms were twisting as the suspension travelled due to wrongly placed strut rods,causing massive toe-in/out changes.
The strut rod bushes were toast too.
Lesson learned as I now have proper tubular triangulated arms and i'm pleased to say the truck's now a pleasure to drive.
