Hello,
I have an issue with the location of the bottom of all 4 shocks on my Mk IV kit. It is a base kit with IRS. The donor is a 1994 Mustang GT 5 speed. I used the front LCA and spindles and the steering rack (which I de-powered) from the donor. I drilled the shock mount in the LCA in the location indicated in the instructions, as best I could determine. I also used the rack extenders and new tie rods from the kit. When I put the wheels on and put it on the ground to check ride height and base alignment I discovered that the tie rods hit the springs at full crank in each direction. The overlap was perhaps as much as 3/8". I drilled new holes for the shock mounts further back in the spring pockets in the LCA and mostly solved the problem. I will cut new spacers to move the shock to get the balance of the room I need.
In the back I installed the shocks with the spacers as indicated in the manual, short in the front and long in the back. When I put the chassis on the ground to check ride height I found that the spring cap hits the tube in front of the shock. I will have to fix that by cutting new spacers to move the eye of the shock.
I would like to know if these are issues unique to me or have others with IRS or donor front suspension had issues installing the shocks according to the manual.
Thanks,
Rick
