The template alone is probably for the 1" Shelby drop. Most of this discussion is regarding the 1 3/4" drop that requires you to reangle the upper ball joint to keep it from binding and ripping out the suspension.66stangmeister said:well, since everyone's talking about these negative wedge kits....I've seen this template deal on eBay, so u know where to drill the new holes in the shock tower. Is that basically all there is to it? or is there another thing u have to do? in addition to moving the upper control arm down and back little bit.
Good enough??? Tough question... The 1" Shelby drop is an improvement and it is free (other than labor). But the 1 3/4" drop with negative wedge (or new/modified arms) is even more of an improvement, coming much closer to ideal, but it also costs $$$ as you'll need to buy the wedge kit or new arms. The 1 3/4" drop is better (my car definitely feels more stable and focused in turns), and I certainly think its cost effective if you need/want improved handling.66stangmeister said:Is the 1" drop good enough or is the 1 3/4" drop better for what its worth?
Does this apply to '65 and 66 only? I've heard that '67 and '68 have a different setup. Is 1 3/4" too much for them?DarkBuddha said:Good enough??? Tough question...

First, Pro-motorsports is probably the best place to contact with these questions, since they originated the negative wedge kit. That said, as far as I am aware, dropping the upper control arms is functional on all years. Again, the maximum amount of drop possible while avoiding balljoint binding is 1" (aka the Shelby drop). This is true with all years.Hack said:Does this apply to '65 and 66 only? I've heard that '67 and '68 have a different setup. Is 1 3/4" too much for them?
How about '69 and '70? I'm going to do a drop on my '70, and I'd rather drill one new set of holes, rather than two. And I'm planning on modifying or having my upper arms modified. With the amount I get to drive the car, regular inspections shouldn't be a problem.
Snail50 said:After much research, I went with the Global West Negative Roll UCAs from Mustangs Unlimited. It seems that the Shelby Drop and Negative Wedge kits, while very effective, don't really introduce true negative camber; rather they reduce overall positive camber due to the length of the stock UCA, and still do not produce "optimum" supension geometry. If I'm wrong in my interpretation, please let me know...although the order is already placed~
I should have them within a week, at which time I will also install my M+ steering kit.
Now that 65fastback2+2 hooked me up with the program to shrink my digital pics (works great, btw...thanks!), I should be able to post pics of the install.
have a great weekend, all!
