MM Road and Track Box

AJHXXXIII · September 23rd, 2009, 09:09 PM

I have a 1991 5.0 LX Hatch and it is stock except for 3.73s and exhaust and I want make it handle awesome for Weekend driving and eventually some Autocross next summer. I was thinking about buying this kit to install over the winter and as I looked through the parts I noticed there are no upc's.

1990-93 Mustang Road & Track Box includes

* MM Road & Track Springs
* MM Caster/Camber Plates (select Black or Chrome finish option)
* Bilstein struts
* Bilstein shocks
* Front and rear Urethane Spring Isolators
* Urethane Pinion Snubber (solid axle Mustangs)
* MM XL Series Full-length Subframe Connectors
* MM Strut Tower Brace
* MM 4-Point K-Member Brace
* MM Panhard Bar with Aluminum Rod
* MM Heavy-duty Rear Lower Control Arms
* MM Solid Steering Shaft
* MM Solid Steering rack Bushings
* Front Swaybar bushings
* Front Swaybar end links
* Front control arm bushings, urethane

Is this because you do not need them or are you supposed to keep the stock ones or what? I would like to hit the drag strip at some point, not often but maybe once or twice a summer, any suggestions? Will this also be a night and day difference in my fox? Thanks in advance for any input anyone can provide.

There is a suspension thread in the modular forum that has tons of great info and is up to date. all i can say about the kit is lose the strut tower brace

Is it just not needed or not very good quality from MM on that part? and thanks for the info I'll check that thread out too.

It is not needed.
You are really doing the right thing by going with a kit. I am a big fan of the MM Kits. If you have never been in a car with full MM parts, you will not believe how it handles when its done... Srsly, like its on rails!!! You WILL be happy with that setup, I promise!!

AJHXXXIII · September 23rd, 2009, 10:33 PM

so i want to get that kit with exception of the strut tower brace? Are there any more parts you would recommend buying or not buying? and thanks for your input so far

AJHXXXIII · September 24th, 2009, 12:03 PM

Ok so I bought that setup today without the strut tower brace. I'm temporarily broke for now, but as soon as I get some extra cash I was going to buy the MM torque arm and eliminate the upcs all together.

um, id just go straight to an aftermarket tubular k member, and convert to coilovers on all 4. And buy a smaller kit from MM (cheaper) id also like to know why to ditch the fron strut brace, when back in the 60's for the trans am races the old stangs had front strut tower braces?

I was wondering that too, but I went through the suspension thread in the 4.6 section and found that the strut tower brace will stiffen the front end suspension decreasing the front grip and also cause some understeer.

ModMustang97GT · November 9th, 2009, 03:27 PM

The brace is good if the rear end is stiff enough. If your rear end is not stiff enough, the brace will make the front end dis-proportionately stiff. This leads to understear. The brace is not really required. I like it because I like the idea of the car being super stiff. But I also think that it is likely that unless you have a cage or the full torque arm set up, that the strut tower brace is probably over kill.

So, I say try it when you get the torque arm installed, otherwise, don't worry about it too much.

Sirl · November 9th, 2009, 04:37 PM

^^ Correct. In fact, I am going back to my stock front sway bar because My rear is very stiff, and I'm getting a push. But thats on the track. On the street, it handles amazing, and still rides well.

you'll need the strut tower brace if you run coilovers. it helps strengthen the strut towers for the lateral forces that would be applied to it.
