TRX Handling Package Question
Hello,
I found a ton of information in books, Google, this site about the TRX package; But because no TRX package was the same, there are a few grey areas. But most of those things don’t matter to much. My question here is about the rear shocks. This maybe not even a TRX upgrade, but maybe we can figure this one out. My rear shock looks to have a coilover setup. It has a shock like normal, with a coil spring slipped over it. It doesn’t look like a current rear coil over, maybe an old 80's version? I'm trying to figure out some details about the coilover. Maybe it's not a coilover, but just a knock off coilover that adds some extra support?? Down the road here, I will be replacing the shocks/struts. I would love to reuse the coilover setup in the rear if I can. One thing I know about the 84 Mustang was, it was the last year of TRX package car to be made. The next year in 85, the GT package was created and some of the TRX equipment was carried over and some of it wasn’t. Also the 87-93 Mustangs had their spindles changed, control arm, other stuff? I plan on replacing the front suspension with the 87-93 parts to accept the newer struts, but is the shocks different too? I do have an 7.5" rearend, so the mounting points would be different. But will swapping an 8.8 solve all my problems? The 87-93 upgrade would be a step before a 5 lug conversion from the junkyard. Quote:
Thanks Everyone! |
It looks like the 8.8 is basically a direct swap.
The break line can be used from the 7.5 on the 8.8, people say. The 8.8 line will need to be extended, or v8 8.8 break lines can be swapped (really don't want to do this!). My 7.5 came with quad shocks, first year. Will a mustang with factory 7.5" rear that has quad shocks; Will the quad shocks fit on the 8.8? I have a 90 mustang in the garage (roommates) I can compair. I'm not sure if I will be able to visually see. I think I'll measure where the plate is mounted to the body, see if its in the same spot. |
You basically have the info for what you want.
Newer 87-93 suspension should bolt right in, might need a newer K member. I do not believe SSP's had TRX suspension. One thing I do know that the TRX had was hopper bars. Why do you want to swap to newer suspension and 5 lug? You basically kill the value of the car, even if you paint it black and white and add all the equipment. You wouldn't be able to use the original steel wheels for a correct look either. Your 84 looks pretty nice. Running and driving, fairly original, I'd say you could get 2k out of it. I would not modify the car. 84's are one of the rarer years now, maybe less than 10 exist that are known? You could sell this car to someone who wants to restore it, and take that money and use it on a newer non SSP coupe. That's what I would do. It is your car though, you can do as you wish. I just like to see these cars restored instead of modified. Just the way I am. Your car is about the 6th 84 I've seen so far. |
True.
But drum brakes are garbage. I've already had a few rear tire lockups when under heavy breaking. If anything it's a safety improvement. I don't want to make the mustang a weekend show car, but get some use on the road and be seen. If the car was still in service (the Highway Patrol doing the modifications) why wouldn’t they upgrade to rear discs? Not to mention the 87-93 suspension is a great improvement too. But you bring up a major question I have in relation to this. What kind of laws and problems would I face painting it black/white and having special service equipment in the car? I would think cops would stop you often, and may even question your right to be driving the car? I know the decals can be magnets and removed, but other then that it still looks like a cop car and could be seen as impersonation? Maybe it can be registered as historical vehicle with no registration for life? Hell if I know. Maybe someone can shed some light on that? |
There were "TR Handling Suspension" (through '84 for Mustang and '85 for Capri) and "Handling Suspension" (called "Special Handling" after '84)packages, and they included additonal items to, or replacement items in, the 'regular' suspension. One example of an "additional item" that the 'regular' suspension did not have but the TR and Handling packages did would be a rear stabilizer bar. The TR package was standard on the '79 Pace Car, '79-81 Cobra, '81-'83 Black Magic, and '83 Crimson Cat and optional on everything else. The Handling package was included/required/mandatory with the turbocharged four-cylinder and the eight-cylinders.
Both packages had their own specific struts and shocks, front and rear stabilizer bar diameters, and front and rear spring rates. I can list the specifics of each package's stabilizar bars diameters and spring rates, if need be. Each package had "slapper bar" (through mid-'84) or Quadra-Shock rear suspension (mid-'84 and later). The TR package also required/included forged metric aluminum ("TRX") wheels and Michelin TRX tires. |
Well I do have quad shocks, and a rear sway bar; Which wasn't common for that year, I believe. I'm sure when the CHP orders the SSP, it would come fully loaded in the suspension dept..
I could measure the sway bars and see if I can read some info on the shock/struts. Then post the data here for you to reference. Thanks for the info. |
Rear sway bar was part of the Handling Package and TR Handling Package. Quadra-Shock rear suspension was part of the Handling Suspension package and TR Handling Package starting in mid '84. ALL Capri and Mustang coupes, convertibles, and hatchbacks with a 2.3T or 5.0L engine had the Handling Package.
The SSP had the same suspension parts that "civilian" 5.0L coupes (and convertibles and hatchbacks) had. SSPs did not get additional or "special" suspension parts. |
No TR package was the same, you could order it anyone you wanted.
The GT package had a standard list of parts. It was nothing that a civilian couldn't get, but did a civilian order it fully loaded with a ford service plan? http://imageshack.us/a/img834/9688/imagejvw.jpg |

the suspension might be a cheap ebay one and if you are trying to prevent lock ups by going to discs it still can lock up due to no abs, until 1994 when the mustangs got the sn95 platform that came with disc brakes ABS and 5 lug

Everywhere I read about it, it says "TRX" not TR. Maybe we aren't talking about the same thing? I got that information out of: The Official Ford Mustang 5.0: Technical Reference & Performance Handbook, 1979-1993. I'll check it out later and see if I'm mistaken. But I remember reading it in the book. Quote:
So you're saying that after the CHP ordered the SSP car, they modified the suspension themselves? What I was saying was, the TRX package was the predecessor of the GT package. The GT package was a standard list of items, all GTs were the same. The SSP (from what I remember reading) was a special order car. I'm not saying the SSP had special options, I'm saying that it was ordered special with all the options available. Which may not included the same options as a mustang sitting at a Ford dealership at the time. I'd like to look up what I'm referring to, no point on going off of my memory. I can quote out of the book, and we can deceiver its meaning. Quote:
This is not eBay, no one makes parts for the 79-86 range. This was put on by A) Ford, or B) CHP in 1983/4 when they purchased the SSP. This car seems to be super original, nothing has been changed. Things that were damaged have been replaced, IE: Dash top, Seats. That could have been changed by the dept, considering every mustang has the dash top cracked by the sun, and the seats were known to wear out. There's no reason for me to think some kid installed the rear coilover thing. If you go search the internet, you wont find any coilover kit that looks like this. IE: one off, or maybe the last year of the TRX package they had a coilover option. Since we have some conflicting information here, I'll do my homework again and get back to you. Thanks for taking time to respond. |
upr also makes them and it doesnt have to be between 79-86 that suspension setup lasted till 2004 thus some parts on the suspension ie coil overs can be used on other years too my upper and lower bbk control arms can go on a 79-98 my springs can be used on any 79-04 mustang v8 hardtop shocks and sruts are a little different you can get ones that work on 84-04 or some that work 79-04

Thing is, CHP would never tamper with the mechanical/suspension side of the cars. They would not put disk brakes, or upgrade suspension, or swap motors, or ...
They modify the car, they are open to lawsuits of something happened. That's one of the reasons they don't put strobes in their cars, it's against the vehicle code and tampers with DOT safety standards. |

the only thing chp may do was subframe connectors on some cars but not all cars had it from chp
|
I've seen a few articles where the department did their own upgrades.
They were having problems keeping up with cars equipped with aftermarket parts. So they added some performance parts, and safety equipment. They featured it in some Mustang magazines. I'm sure you are most likely right, aftermarket. But it seems like a possibility that it could have been used in service like this. The subframe connectors look old, and were welded on (similar to the wields for the c pillar and rear fender antenna from decommission). I did a car fax on the car, and it had no DMV record until 1994. From what I remember about the cars history from the man I bought it from. The car was owned by a young dumb kid, and he didn’t know how to work on it. So he took it to a local automotive shop, they did repairs to the car. The bill was never pair, and the car was sold to another mechanic as a lean sale. It sat for a while and then I bought it in early 2011. The subframe connector, rear coil over and 4 barrel eddlebrock carb is the only thing changed on the car when I got it. I was hoping someone else might of had someone setup like this, but I guess not. |
TR and TRX is the same thing. Mercury called it "TR" after '81(?), that's where I got it from.
What you quoted above about the TRX and Handling/GT suspension is exactly what I said. There's nothing in there about being able to pick and choose parts within those packages. And if you ordered a V8 or a turbo 2.3L, the Handling/GT suspension was not optional. It was mandatory. The TRX suspension was optional on everything (except the models I listed on page 1), even the V8s and turbo 2.3, but the TRX parts replaced the Handling/GT suspension parts in those cases. Nothing in the list of SSP-only parts shows anything about the suspension. SSP got the standard Handling/GT suspension. No changes. No extra duty control arms or bushings. No coil-over shocks. No larger (that Handling/GT) stabilizer bars. All standard stuff that every other V8 got. |

Yes out in America some officers slightly modified their mustangs(and were reprimanded for it too). If an agency modified the car any way mechanically(headers, brakes, motors, etc), liability dramatically increases. If something happened, like upgraded brake failure and the car rear ended another car causing injury, the department could easily be sued and would lose. CHP is strict on the no modification rule. Even sub frame connectors would be a no no. These Mustangs are well known for reaching speeds of 130-140 mph. I have a 92 GT. I haven't had any braking problems, brakes perfectly fine, and handles corners with no problems at all. Of course it has the slightly bigger disks, but still. I'm sure Ford would have been sued if these cars have had the rear drum lock up issue you describe since they were new as someone would have been injured. Have you redone the brakes? Brake shoes most likely are adjusted too tight. Also, Mustangs do not have Anti-Lock brakes. Of course they are going to lock up if you stand on the brakes. I'm not trying to bash you. We're just trying to tell you that departments would not swap in new suspensions or modify them. We are a site of preservation and restoration. I'm not opposed to internal motor mods, but when you swap suspension to something newer, the car will not have it's same look. When I see a modified SSP, I don't generally care for it(there are a couple that I really like though). Ruins it's respectability IMO. Unless you can make contact with every owner, you can't prove that the modifications to the car were put on during it's service life. |
there is a shop owner down the street and he said that a few of them had subframe connectors from chp not all of them had them but he has seen them on the cars and he bought a few of them through chp like that
