Just in case you haven't ordered yet I will give another vote to Stifflers. Simply incredible the difference it made for my car and I use the jacking rails all the time. Well worth the extra effort for both the result and future convenience.

That looks like a good system. Kinda tempted.

Another vote for stifflers. The entire catalog is under my car.

I am also running the entire Stifflers catalog for my 2000 mustang. The car feels so much more solid than before.

I wanted to get the stifflers but I just received a credit from MM and I need to use it. I’m going to see if I can get money back instead.
If I can’t get my money back MM SFC will work just fine for a street car.

You can still add the fit system to your MM subframes later on.

The stifflers fit system braces work on MM subframe connectors? Have you seen it work?

I haven’t ordered yet. The thing is the pinch weld along the side of the body is fairly bent. Looks like they tried lifting the car from there many times. I’m thinking that might be an interference issue with the jacking rails. Overall the body seems straight just that pinch weld down the sides of the body.

Hammer or vice grip them back to being straight then add the stifflers kit. I have the old kenny brown extreme matrix kit on my car. It too is fantastic, my buddies car has the stifflers fit system as seen above. Even better!

The Stifflers fit system is designed to work with any subframe connectors. Go to the Stifflers site and look for the installation instructions to see how they fit together.

I did see the system can be purchased separately. One piece at time.

Ive been good friends with the owner brian for about 10 years. I joke with him all the time about being a salesman as i know everything about their products. He even helped me out and made a custom set of drop mounts for my rear coilovers. There is no problem adding to the MM subframes. Its the connectors that arent full length that wont allow the addition of the fit system. Just be prepared for some upside-down welding when you do purchase them. Also if you can catch them at a show or track event youll get a better price.

My plan is to get the full length connectors not the short ones.
By upside down welding you mean welding on the floor or like difficult welding?

sparks falling on you welding, you know the fun kind. If you are not partially afraid you will set yourself on fire then how do you know you doing it right?

Oh yeah I have welded some stuff in the past I’m ready for the weld slag falling on me. I got shirts, gloves, face mask, beanie and all the good stuff.

You guys were right welding these subframe connectors on jack stands is a biatch. I Couldn’t use the full welding mask so I used the half mask. I burnt my eyes. Mostly my left eye. So I went and got welding goggles. Now I burnt my face. But I’m done now, the damn things are welded on. Car feels good and has a lot less noises.

but its fun dancing while laying on the ground! Sure it looks like your having a seizure but if your neighbors were smart they would just get a beer, pull up a chair and enjoy the cursing show! Glad you got it done.

3 ton truck jackstands are your friend.. plenty of room to roll around

I learned that potatoes on your eyes help tremendously when you burn your eyes.
That sand in your eye feeling sucks.

I'd say remove your entire carpet from the car just to be safe. That's what me and some friends did way back when we did my car. This is the only good pic I have of the SFCs along with the previous rear suspension setup. But if you zoom in you can see it's a bit different than Stifflers or MM. These are square steel pieces with the jacking rails and the triangulations from outside to inside. Mine is a vert so the difference before and after was night and day.
