I did a search and found nothing that answer my ?

I have standard MM connectors on my 91, and full length MM connectors on my 99. I would do the full lengths on my 91 if I had to do it all over again. The 99 is stiffer then the 91, plus I can jack the 99 up using the connectors if I want, where as I can't on the 91.

I not only have full length but I also have a matrix brace... more stability is better.

Not sure of the difference but I have full length MM subframes and I love them. Significantly improved handling.

Do the full length sfc's so u don't kick yourself later. Cause it will cost you more if you try to add on later + that will never be as strong or solid as the 1 piece flsfc.

Do the full length subframe connectors. The stock sn95 frame is designed to be stiff while saving as much weight as possible. The frame is very spread out and works as a thin matrix of strong points. Despite this matrix, the entire midsection of the car has a significant amount of flex considering that it has to support two separate axles.

That extra 10" of material covers the entire length of the bottom of the car from the firewall to the rear control arms- exactly the area that needs as much support as possible and that makes a big difference. A standard subframe cuts you short and doesn't fully connect axle to axle. So you end up having a weak link and a section of 10" of "normal" sn95 flex. But since everything else is stronger that focal weak area is going to experience significantly more stress/strain than before. So you will be mostly stronger but you will sacrifice a surprising amount of rigidity (the 50% figure doesn't surprise me) by going to a standard subframe and that one area is going to flex substancially more... you won't break things but I learned a long time ago, if you are going to do it, do it right. The mechanics/physics support the full lengths.

Full length subframes are by far top 3 on the bang for buck list for our cars. They will be a better modification than everything you have in your signature right now. Yeah it is $75, but after you get them on you will realize it was totally worth it. If you don't have the money now than save one more month, again, full lengths FTW.

Do it the right way off the bat. You'll end up regretting it later. Buy them off americanmuscle.com and find a reputable shop that will do it for $150 or less and call it a day.

well I wouldn't buy them off American muscle seeing that I live about 5 miles away from MM shop.

But finding a shop to install them has been the problem. I have called around and a lot of them don't like full length on mustangs because you are welding right next to the fuel line.

I have a friend that owns a muffler shop and he wants me to help him install them because this will be his first modern car. Has install subframe connectors on lots of classic muscle cars.

If you live only 5 miles away from MM, ask them how much they get to install them for. On their website it says they install all of their products and I would bet it's a little more than the average person but then again maybe not since they could knock it out fast.

As for the question about the other brand of connectors, I have never heard of them but that isn't saying much. If no one else has though on here then that would speak louder I guess. I'd still choose the company with all the mustang experience personally.

id go full length, i love mine!
