Yeah ah few of us have done it, and done correctly it works very well. Just like the arning drop or (shelby drop) as its known. you move it out 1". This will stiffen up the suspension considerablely and raise the front end about 1". to counteract this you'll need to run a lighter 6 cylinder spring. Putting the spring closer to the top of the spindle transfers more of the energy to the spring rather then the chassis. Giving you a better ,more controlled ride. Mine felt almost like a modern car after I did this.....

I did the shelby drop and I have 450-550 progressive springs on the front. Before I moved the spring perch, it felt way too soft for my liking and on large bumps in the road, it would bottom out. I moved the perch and it drove like a new car. Stiff, like I wanted, but not harsh. The strange side-effect of moving the perch is it also increased the dampening rate of the shocks. To me, that was the most noticable change. It took me about 2 hours to move the perches, including making a template and everything.

It is a free modifiaction that you can easily undo if you don't like it. Do it.

So it sounds like I need t use roller perches, 6 cylinder springs and do the arnying drop.  Will this be too stiff If use my v-8 springs.

 When I first did mine I had the V8 springs in it and it was way too stiff. Sal came up with the idea of using 6cyl springs and it worked perfect for my car. My coupe was pretty light though ,aluminum everything, no air, power steering or brakes. I put the car on the scales. Even with ah half tank of gas it came in at 2640.00 lbs

Here is the Mustang after the Arning drop but before the perch relocation.

Nice ride ! Now just need to decide 3/4 or 1 inch. Did you build your own roller perches?

No, I bought them.
