This topic was started a couple of days ago, but the VMF is so popular that any post will disappear to pages 3,4 or 5 too quickly. I asked the question about the location of the modified A arm. If the A arm is "lowered" does that mean that its new location is 1 inch below the original location? It seems to me that would raise the front end of the Mustang. I have coils from a Mustang that had a big block with one coil cut. I also made a template, when I worked at my uncles machine shop, so that the new holes will be exactly 1 inch from their original location. fd

With this mod, the suspension will stay the same or lower height. It will definitely NOT raise the front. Remember, the coil is not a pivot point, the ball joint is. Definitely a worthwhile mod, you'll be glad you did.

Thanks for the quick reply art, but now my keyboard is all wet with drewl from looking at Tony B site. I bought stuff from him many years ago for my 67 GT500 project car. He was very helpfull over the phone. This was back in the early 80's before we had this internet thing. fd

Ok....I'm going to show my ignorance. I've been around cars for a longtime, and as you can tell by my project car, I'm not affraid to try anything. But, what does lowering the A Arm do?

We do it to all of our cars. Even if they are not a track car,
it helps the front end geometry and is FREE to do. 1" down
and 1/8 back. Put in a bigger sway bar and you will really like
it. You do have to have the front end aligned after. I take out
1/4" of spacers to start off with and let the shop to the rest.

I hope everyone notices it's not really 1/8" rearward (nor 1" downward).

The measurements are relative to the line defined by the centers of the existing holes. If you go 1" straight down and 1/8" rearward you'll have even more negative camber under load and more caster as well!

I found the mod lowered my car 1/4" lower.
Definately will not raise the car up :)

Thanks again Roadracer. Now I have one more fact when thinking about suspension geometry.
Also my 2 cents: relocating A-arms affects also roll axis of the car, not only camber changes. But frankly, my dears, I don't have a clue about roll axis, just something I read.
