I had an '05 that i had Steeda torque box braces...they were bolt on. I noticed a difference in the rear of car..being tighter and less flex when in car...when i finally welded them in...it was even better...they did make a noticeable differnece ...especially on my bumpy road state of NY...i have sold car and now have '07...i want to do a brace of some sort again...kinda wondering if the tubular BMR subframe connectors would be even better...and alot less money...anyone have subframe connectors? is it worth it or not? I don't race car...but want to take out some of body twist and creaking. I know this new body platform is pretty rigid...but there is always room for improvement..

 

I have the BMR boxed subs and I say they are great. I'm not a racer either, but I like my ride as stable as possible for any driving conditions. The boxed subs made a great deal of difference in the rigidity of the chassis.

The tubular subs will make it better, but the boxed will really stiffen it up.

Here's a couple of pics of mine. Sorry, they are black and kinda difficult to see.

i have the boxed BMR ones, i live in manhattan, and let me tell you, the car feels much more solid now. well worth it IMO

 

Despite how much more rigid the S197 chassis is compared to earlier Mustangs I would have to agree that sub frame connectors are a good idea for any uni-body car. Does anyone know how much more weight they add? I would imagine very little and certainly what ever weight penalty would be worth the increase in structual rigidity. Just curious.

 

they are like 20lbs or something

 

you only weld each end of those connecetors??????

 

The BMR tubular subs are only welded at each end, the boxed ones are welded on each end and at two spots on the inner side of the frame as well.

Nay....These cars are rigid and you are basically adding dead weight to the car. Notice that BMR is the only company(that I know of) selling SFC's. Steeda, Griggs, MM etc aren't.

 

how many times do i gotta say this. DRIVE WITH THEM AND WITHOUT ON THE FDR AND SEE IF YOU WANT THEM.

 

Anyone have the tubes? Do you have to pull up the carpet to weld them on?

 

buy the boxed, and u dont.

 

That's scientific. It's like the guys that claim that Strut tower bars make huge differences. Griggs, MM, and Steeda DO NOT sell SFC's. They are in the business to pedal parts for Mustang suspensions. They all don't see it necessary to equip S197's with SFCs.....enough said.

 

That's the worst reasoning I've ever seen. Steeda doesn't sell driveshafts either, does this mean it is not worth the money? Drive a car with the stock driveshaft then drive one with an aluminum one... you're so blind.

 

Blind? It's perfect logic if you have commen sense. STEEDA IS IN THE BUSINESS TO SELL SUSPENSION PARTS ($$$). Please provide some technical data that disputes Multimatic, Ford Racing, Steeda, Griggs, and Maximum Motorsports. If you notice, those companies are again in the business to sell suspension parts (road racing). A fool and his money are soon parted.......

Steeda:
We spent countless hours fiquring out where the S197 Mustangs could benefit most from chassis stiffening. Here is the end result....Made from 4130 Chrome Moly material this brace is specifically designed for the S197 Mustang. It ties together the inner/outer frame rails and the rear lower control arm mount. Braces are Yellow zinc plated and come with mounting hardware. Can be bolted with supplied hardware but a welded installation is recommeded for maximum benefit from this brace.

Griggs:

The S197 chassis is a major departure from all other previous Mustangs from the standpoint of structural rigidity and geometry. Structurally, the tub, or Unit body frame work is extensively superior to all other Mustangs, to the degree that we deemed it unnecessary to add chassis stiffening devices in the manner of subframe connectors and/or frame kits unnecessary for all but the most serious of competition vehicles. However, the geometry required a second look.

either way, your reasoning is still wrong.

 

Based on what technical data or professional opinion from companies that engineer race components? Please come forward with the information you are witholding.

Steeda sells suspension parts, as does Griggs. If they thought that they were worth it on the S197, you **** well better believe that they would be in the market. You must of been asleep in business 101.

If BMR sold this, would you still buy it?

 

....wow..guys...don't get all heated...lol Thank you all for the response...especially the guys with the BMR stuf...that have a before and after experience. Like i said...i had the Steeda braces in the other car...and YES...you will notice a stiffer rear of car...you can prove it to people...example...backing out of a steep driveway and turning as you backed out...car would creak a bit...or some other weird noise...after braces...never happened again. Also traveling the same roads to work everyday...many bumps were undetectable...and the rest were subdued alot...you didn't feel like the car was wiggleing around in back....SO...this is why i figured that the subframe connectors would be even better..Ever open your door with car up on stands...Notice how it opens and shuts just a bit off..thats flex in my book!

 

MM will sell them. MM is still in R&D for s197 parts.

 

I have installed subframes because I believe they improve the rigidity of the body in a uni-body constructed car... it may be true that you notice less of a difference with the new S-197 chassis.

Expensive test equipment and track time is the only true way to get the 'hard data' to determine how much of a benefit they acutally make. I don't have that luxury. My method is much simpler... I measure it through the steering wheel and my ***. That's enough proof for me. I'm happy as a pig in a mud hole... and that's all that matters. I certainly don't think I have wasted my money.

We've done alot of the full length boxed subframes with nothing but great reviews from customers. Sure its not the same as on the old fox body mustangs, but you feel a difference.

I actually only have one set left in stock since our last stocking order that was only 1-2 weeks ago... a pretty hot item if you ask me.
