rear end adjustment

[mikesmk111]

i have a ffr mk111 with a Levy racing 5 link rear suspension system using a watts link set up. My question is how to adjust the axle to center it under the chassis. it is riding with the right tire 1 inch outside the wheel well and the left 1 inch inside the wheel well. do i just adjust the watts linkage evenly to center the axle or is there something else i should know?

Call Gordon Levy and talk to him. A super knowledegable guy. He has built and sold many of those systems and should know whether it is the rear end or the body that needs to be moved or both and how to do it.

How does it measure against the frame? You really want it centered in the frame.

2x, center on the frame not the body.

x3 center frame, not body. and YES i tried the center with body thing too!

i did mine with blocks of wood and a chopsaw. mine was off by 1/16" when i went for 4-wheel alignment.

Gordon said you can lengthen wheelbase by 3/4" (compared to Stock Mustang arms) and that will help handling. this is a 90" wheebase car by design, and wouldn't you know it, my wheelbase is 90 3/4"!

• lower arms: to start, try to get each wheel to 90 3/4"
• lower arms: measure between flat end of main round tubes and a convenient part on the axle.
• side-to-side: block of wood between top inner rim and frame.

let me know if you want me to measure lower control arm length to get you started. my car is up on blocks now and very easy to get in there. i have MK3 with 315's, but lower arms will be the same no matter what.

do not underestimate the importance of adjusting the 3rd link to get the driveshaft pinion angle correct. one of the best things about this 5-link setup.

here you go, dude. you need to get the car on all fours like in my photo.

my lower control arms lengths ~18.5 inches
right arm like in photo above ~12 inches
left arm like in photo above ~11 inches

do a search for ffcars.com pinion angle to see what that's all about.
