Sneak Peak - BMR's New S197 Rear Sway Bar

[Norm Peterson]

The true rate, as you know - is likely to be on the softer side of the "Bar" ratings that we, as well as OEM, typically use and provide/advertise.

Absolutely. Mr. Puhn's formula only addresses the two largest contributions to bar end deflection, center section torsion and arm bending. There are several other little components of overall deflection, but in most cases his formula only over-estimated bar stiffness (relative to including more terms) by maybe 5%.

Anybody who could reliably notice a 5% change in bar stiffness and identify where it was coming from is either a test driver or might do well to consider a career change.




Now I'll tell you that I threw a couple of your sets of dimensions into a spreadsheet of mine that uses Puhn's formula as a sanity check, and damned if the numbers didn't match Puhn right down to the exact same lb/in. That book of his is still a good reference.

I agree 107.7% with everything you just stated Norm, as I am sure you probably already knew that.

 

[BMR Tech]

No big deal, since we are so late to the game with these....but here is a shot of our new adjustable front sway bar end links. They are pretty nice. I am very happy with the way they came out.




More to come.

Do you have an idea on the price for the new rear bar?

 

[BMR Tech]

I do not, yet. We are trying to finalize the costing right now. It' won't be "cheap" - but it shouldn't be "too" expensive, either.

I guess somewhere in the $350 range, for the complete rear kit (bar, saddles/bushings, end links, brackets)

 

[07graygt]

Who cares about price just get it done and axle brace too!! I have upr relo brackets but I think I'm gonna switch over when this and axle brace comes out. Wife is gonna be pissed lol.

Love that set up!

Rear Billet End Links drive the cost up to a point we are not comfortable with, for this particular piece.

So, we are likely going to use a fabricated version similar to this.

Ha tell me about it, I want the billets for your current model which mine does not have (must have been early run?) but I have a hard time justifying the cost even though I know they're extremely high quality and not cheap to make.

I do like how your company is working all these new projects for an "outgoing" platform . So I gotta ask, do manufacturers work something out so you get a new version to create parts on early, or you are stuck waiting for the public release date/rush of buyers?

If you want to upgrade to the Billet Design, I can work out a deal for ya. Just shoot me a call.

As far as the new platform - I am not sure about other companies, but, we simply just buy the car when it is available. We pull it in our facility, rip it apart, and start the development. I know that a few companies start developing "pre" release....from drawings/prints that are available to a few of us.

Those hammertone endlinks are sexyyyyy

Reps from a couple of the big name outfits have spoken at the local club & have specifically said they get CAD data (and possibly pre-production cars--my memory is fuzzy on that) from Ford. So AFAIK, those guys are already developing parts for the '15 now. One has even gone so far as to say they do some of the engineering work for Ford--or at least that's how I interpreted it.

 

[BMR Tech]

^ I'd take that info with a grain of salt.

I am not saying it is impossible, but, the companies that we directly compete with - don't have cars to engineer parts for "ahead" of time. Of course, they may want to insinuate that is the case, but, it's not.

Correct, we could have started our engineering already on the car (with prints), but, in our experience....it's best to get our hands on the real deal. We have learned some lessons in our short 20 year history.

Designing pieces from dimensions on paper, is better suited for "other" items, like "bling" pieces.....shifters...air intakes, etc.

Suspension needs to be done with the production car, in hand.

 

[Sky Render]

Roush and Steeda are contractors under FoMoCo for some development, so they might get CAD info. I doubt too many others do.

Not that it's suspension but some aftermarkets have made small run parts for Ford as well, like SHR's louvered qtr window's for the Cobra Jet's.

 

[BMR Tech]

I don't doubt that. We do some similar stuff, for other companies like that, as well.

My point is, most people have a slightly twisted perception about the reality of the aftermarket supplier's relationship with OEM.

As for the Cobra Jet and Boss 302R, etc....I wouldn't hesitate to claim that our engineering and components are on par, if not better, than the products being used on those cars. Heck, the Cobra Jet UCA and Mount are direct replications of our parts. The company who built them, ordered our UCA and Mount (several of them) to use, in developing those pieces. They ended up being basically direct copies.

Cobra Jet UCA/Mount:

 

[claudermilk]

Yeah, several grains of salt. Roush was one of the ones making the claim, and I do tend to take that at more-or-less face value. My perception is that 99% of aftermarket supplier's relationship with the OEM is "you're on your own" and they have to get test mules purchased like any of we normal customers to develop on. Thus seeing many calls for test cars over the years.

Thats pretty funny, oh well just keep doing what you guys do, obviously working!

Cobra Jet UCA/Mount:

The "FRPP" 302S/R bumpsteer kit is sourced through MM. It's an MM kit with an FRPP decal on top of the MM decal, on the box.

I figured Ford did the same with BMR and the CJ uca and bracket. Would the only difference be the materials? It'd be one thing if the part just came on the CJ, but FRPP sells it aftermarket. They should have either sourced it from BMR or engineered their own. IMO.

You mean like this?

http://www.bmrsuspension.com/index.cfm?page=products&vehicleid=1&maincatid=21&catid=62&productid=185

That bar is 146lb/in.

Hello,

Does this bar (SB023) mount in the exact same locations as the factory rear bar of a 2013 Brembo GT? Do the ends of the bar extend any further outboard (ie..closer to the wheels) from the axle mounting points then the factory bar?

And lastly as final confirmation, if I were to lay the factory bar on the ground along side the 22mm BMR offering would they match up as far as the bends go?

I'm in the market for a smaller rear bar and the 146lb/in rate is were I think I need to be but the routing of said bar must be the same as the factory one since I know that works with all my other aftermarket parts out back as far as clearances go. If all the stars don't line up I guess my alternative would be the OEM 2011+ V6 rear bar with the same rate.

Thanks

Any update on when this will be released?
