thanks arthur
now have that mod back on the list for sure!!

Rorin are you going to drop yours again some day?

 

Thinkin' it's now back on my to-do list as well. The front needs to come down a little as well, so hopefully this will do the trick.

Though, I think I'll check everything over by putting a load on the lca when the car is on jacks, to see how everything looks in there and to see suspension travel range before hitting the bump stop. As my daily driver in L.A., I come across speed-bumps often (at a reaonable speed - i.e. not fast), which are my biggest concern with this mod.

Gonna try my hands at the home-alignment soon, so I figure I'll do it all then. Another project for the summer...

 

Not to my knowledge. But I did call a retired front end shoop owner who also worked for Ford as the front-end shop forman back in those days and he said the dropped arm had noting to do with ball-joint wear....but the 620 lb springs had a lot to do with it. With this design the majority of the load is exerted on the upper arm and that joint ALWAYS wears out first then you increase the spring rate from what...380 to 620 and that upper bal-joint is half-lifed.

I would not recommend you do the 1" drop in this day and age...not with the 15 degree wedge and 1.75" drop that totally eliminates understeer.

 

I agree with you in principal Mike, but the change you are talking about costs a lot more than the few hours labour to do the original drop!

 

But now think about this...with the Shelby mod you ae going to run 1/2 to 1 degree negative camber to get the front tire to spuare-up to the road in corners. This wears your tires out VERY quickly. With the 1.75" drop you run 0 degrees camber and your front gains about 1 degree per in of suspension compression. I've run the Global-West since they 1st introduced it back around 1990...just can't remember exatly when and my tire wear has more than paid for the extra cost of the system.
One more thing...if you decide later to go with the 1.75" drop...what do you do with the holes you now have?

I must not drive as aggresively as you...
My last set of tires still wore out the outsides faster than the insides with -1° negative camber and the 1" upper control arm drop.

 

Wouldn't that mean you were driving MORE aggresively than I?

Scott,

I actually happen to have that "set" of upper arms John made
So far (with limited testing), a set of stock V8 coil springs (cut to achieve proper ride height) with the spring perch moved out toward the ball joint (about 2 inches) has provided positive results. So far, it definitely appears to be superior to running a set of 560 or 620 springs in the stock location.

I have a full day of testing at the track scheduled in April. I hope to come to a conclusion soon after.

Mike, you're right... guess I am taking corners a bit harder, lol
No wonder I like negative camber so much!
