Hey all,
I'm considering the Shelby drop for my 70 Mav but don't know if I need to do anything different than the mustang version. I have read that there are 2 different drop methods based on the year of the car and am not sure which I need. Does anyone have a solid answer?

Has anyone done this and noticed better handling?

Thanks
Dave

You should be able to use the 67-70 mustang template. your holes will be straight down 1" perpendicular to the centerline of the original holes. The 65/66 Mustangs are 1" down and a 1/8" back but you may run into shock tower interference moving the control arm back. The 67-70 Mustang uses the wider 4 3/4" bolt pattern on the upper arm which I belive is the same as the Mavericks and the 65/66 Mustangs are narrower at 3 3/4" between bolt holes.

the suspension is essentially the same as 68 and up mustang, so use the corresponding template.
the mod is quick and inexpensive and proves to give the same improvements as with the mustang.
note that although you drop the control arm by one inch, the car will not come down a full inch, but more likely 1/2 to 3/4.

Thought I'd throw-in here, the "Shelby" drop is mentioned when the arm is dropped 1". This was done by Shelby because going to the full 1.5" drop described by Klaus Arning (the design engineer) meant changing the angle of the upper ball joint, as full suspension travel would stress the joint otherwise. This ball joint angle change is commonly done with 'negative wedge' plates. So, Shelby kept it at 1" for most of his 'production' cars, but you can go to the 1.5" drop to optimize geometry if you wish. Just use the plates or aftermarket UA arms that have the angle built-in.

Lots of stuff affects the final ride height including alignment, but geometrically, the chassis drop is ~0.4" per inch of A-arm drop. YMMV

Awesome. Thanks guys. Once my shop is built, I'll get the car in and start working on it. This will be at the top of my list.

Dave, great info there. Good to know but I'll stick with the simple 1". It's a street car and not a full blown racer.
