Pace car build

[cougman67]

Works now

[cougman67]

I decided to use ditzler hot rod black for the bottom of the car. It’s a single stage paint that seems to spray easily.

[cougman67]

Today it was time to install the differential. I purchased more maximum Motorsport parts based on their recommendation.

The upper control arms are factory 94-04 units and the lowers are way to expensive but should keep me from wheel hopping. I purchased the lowers that included a height adjustment.

I noticed when I was installing everything that the upper control arms don’t align very well. I’m not sure if anyone else has noticed it, please let me know if you have.

You just experienced the inherit binding in the Fox rear suspension.

Unfortunately that is the case with virtually every one I have ever worked on in my life. The best trick I have found when swapping rear ends is to install the upper arms first and then the lowers. You have a little more room to work with the lowers and makes it easier (at least for Me) to move the rear axle around to line everything up.

The PC is looking good! I am sure you are excited!

Things are looking good!

On steering adjustment question/comment a while ago — it really depends upon what you plan to do with the car and what parts are in the final build.

If you have a lower K brace and a quality strut tower brace and a strong front sway bar you will not need as much negative camber preloaded into the front suspension as you would if any of those factors are not there.

I would start by figuring out the maximum amount of caster I can get that’s equal on both sides. As much as possible.

Next I would dial in not more than -1.75 Camber. If I don’t corner very aggressively on a regular basis then -1.25 to -1.5 is more reasonable. You can end up with camber thrust where it feels like the car is skating with wide tires and lots of negative camber on uneven surfaces.

Make it equal both sides. You may need to loosen the struts and put a bar or jack on the hub to force movement towards negative camber or elongate the upper strut mount bolt hole or use camber bolts.

As a last step I would set my toe. With a high quality bumpsteer kit like that you are not going to get near the fluctuation in toe that you get with stock outer ends.

I would probably go with 1/16” toe in (narrower towards the front of the car) as a starting point.

Thanks everyone. A few pictures of the black and my rear suspension.

If anyone can flip these pictures, it would be appreciated.

Done!

Looks good!

It’s Saturday and I installed the rear Calipers. I have questions for all of you:

1. How do I install maximum Motorsport MMBK1R. From what I understand, the kit replaces the existing hose on the differential. I purchased a full 1988 mustang hard line kit. I understood the brake lines for the newer cars ran to the drivers side. If that is correct, the line will not match up.
2. Does anyone have pictures of the brakes lines installed so I can understand how this will all work together?

Hose location



Best guess as to the brake hose connection

[wraithracing]

You need the 8.8 rear brake center hose/bracket.



The rubber hose will be removed from the bracket. The bracket will bolt thru the hole in the web of the rear axle housing just to the side of the pinion flange. The stud will drop in the hole and be secured with a lock nut. The new MM brake hose will attach to the bracket and then the new hard brake lines will connect to the MM braided hose.

The bracket you have the MM hose attached to right now will get riveted to the underside of the car just next to the clips for the muffler/tail pipe. This is totally different than the 79 PC rear brake routing. Actually only the 85 V8 and then the 86-93 V8 cars use this brake line routing.

This is what is looks like on a 1985 although the bracket on the body is different than yours and the 86-93 v8 cars. I have to swap out the same bracket on Erratic50's Saleen Clone.



Here is a picture of the filthy underside but at least shows you roughly how the rear brake line is run.





I haven't installed the rear axle back into the Saleen clone yet, otherwise I would have better, clean pictures showing you just what you need. Hope that helps!

[cougman67]

Thanks Trey. Well you have a camera, could you please take a picture of where the breather attaches to the axle. Would you also be able to take a few pictures where the proportioning valve lines go to the front brakes.

I owe you.

I’m in the Process of installing the front brake lights. I cannot seem to install the left front brake line into the proportioning valve. It looks like the fitting has not been double flare. Has anyone else experienced this?

The classic tube lines took some finesse to fit. The subframe connectors gave me some grief.

Which proportioning valve and M/C are you using? The line here appears to be for the later Aero model cars with the bubble flare. The 79-86 cars and proportioning valve would have the same flare on both ends.

I can get you pictures of both the early 4 eyed cars and the later Aero cars brake plumbing if you like.

what was the reason you bought 94-04 upper control arms instead of 79-93, and how are they different?

There is no real difference. The same arms work from 79-04. If buying from Ford, then part number may have been updated to a SN95 part number, but they are all interchangeable.

[wraithracing]

Here are a couple of pictures. Hope they help!

79-86 M/C and Proportioning Valve plumbing.



1987-93 M/C and Proportioning Valve plumbing.



This is a 7.5" rear axle, but a 1985 model so it has the same basic rear brake plumbing layout. The bracket bolts to the rear axle and the hose connects to the body plumbing on the driver side of the driveshaft tunnel. You can see the breather tube on the passenger side axle tube.

Pretty sure that front line is designed for the 87-93 3 outlet M/C. If you are not using that M/C then you will need a different line or have to modify that one to work.

Cougrman,

it looks like you have the passenger side caliper on the driver's side of the car. The bleeder screw should be above the brake line.

I purchased newer style upper control arms based on maximum Motorsports recommendations. See an excerpt below from there site.

When installed on a 1979-93 Mustang, these control arms, with their stiffer rubber bushings, help limit axle wind-up and side-to-side motion, but will not damage your Mustang's upper control arm mounting points (torque boxes) as a standard urethane-bushed upper control arm would. See our extended technical information about bushing material choices in our Rear Lower Control Arm tech section.

While for 1994-04 cars these control arms offer no improvement in performance, as they do on Fox chassis cars, they are a great value when replacing arms with damaged or aged bushings. Because rubber deteriorates simply from age, after several years the control arms are ready for replacement. High horsepower cars and those used for track events tend to damage bushings before they can degrade from age. These replacement control arms, along with the axle end bushings, are a great way to bring back or upgrade the performance of your Mustang.

[cougman67]

Thanks trey, I believe your correct. I’m purchasing a newer master cylinder and it looks like this kit is required. I’m still waiting for the master cylinder to arrive.

[cougman67]

Good catch on the brakes. The instructions don’t mention right vs left but I found a letter on them this morning.

Thanks AJ

Its getting too cold to work in the garage.
