Fox Body Mustang Stocker Rear Suspension Question

[Sean Marconette]

On my car I have one of the bars from the hoop welded to the UCA mount area. I learned from a friends stocker T-bird.
Last year I found the LCA mounts cracked, and installed the reinforcement plates that Jegs sells. Best 60' has been 1.51 in K/S

My 85 Mustang started out as a 4 cyl. auto, so all the mounting points were mint, for the uppers, we just solidly welded the brackets to the floorpan, (stock is just spot welded), for the lowers, we used what are commonly refered to as "BattleBoxes", which reinforce the front mounting area. I have Maximum Motorsports tubular lower arms, and the uppers are from Auto Weld, which include diff housing brackets that are similar in design to the Lakewood "No Hop" bars, made for Chevelles. The Auto Weld upper mounts have 2 different mounting positions for the upper tubular arms. Also, if you are using a Ford 8.8 rearend, be sure to have the steel tubes solidly welded to the cast center, a axle tube brace is also a good idea. My best 60 foot in M/Stock is a 1.60, but with my current bracket 331 cube , it has a best of 1.37 60 foot, with the car setup exactly the same, other than a gear ratio change for 5.13 down to 4.88s. I also use stock 5.0 GT rear coils springs, along with an Air Lift bag, and Strange adjustable shocks.

Thanks for all of the suggestions guys! I think we are set for reinforcement. We welded the torque box seams, installed reinforcement kits on both the upper and lower torque boxes (Battle Box-style kits), and welded bars from the main hoop of the cage to the upper torque box.

In regards to the suspension geometry I really appreciate the feedback on what you all have used. It's been really helpful in helping me figure out what direction I want to go. There are a ton of options available that relocate the pickup point on the lower control arms that I am very familiar with, but I have not had experience with the options that relocate the upper control arm mounting point.

Thanks again for the help and keep the ideas coming I will try and post some pics when i get a chance.

In N/SA (3285lbs), my 60 foots are consistently 1.61-1.63 it picks a number and stays on it for the day. I have all the adjustable uppers and spherical bearings but some very basic lowers. I started the season out with moroso trick springs in the back and the body roll was enough for the right rear fender to scrape my tire pretty bad. I switched to eibach with the air bag in right rear and keep 15lbs in it. Might be too much, sometimes the car drives to the left. However I still have body roll. Pinion angle is very important, at least that's what I gathered from Dick Miller's book.
