Sneak Peak - BMR's New S197 Rear Sway Bar

[fdjizm]

Fuck yo turns!

 

[luillo]

I am a little confused. What would be the axle brace for? To avoid the housing from bending like the CHE intent to?

Oh damn forgot the section! Carry on
Yes and work with bmr parts, Kelly said he had an awesome design in mind.

Axle brace??? ,wtf...drag racers! BOYCOTT. WE WANT THE WATTS

This, the fuck is BMR doing trying to cater to a hobby they are already KNOWN to cater to! I would rather BMR spend the money to reach out into a needed market for them than to continue to produce dead weight to hang from the rear axle.

I am a little confused. What would be the axle brace for? To avoid the housing from bending like the CHE intent to?

That's the goal I assume BUT with the CHE brace you are adding a lot of weight for not a lot of strengthening. The CHE brace hangs under the axle which is not how I would orient a brace if my goal was to increase the rigidity of a live axle on hard launches. I would want it basically on the same level of the axle across the diff cover or around the front to actually strengthen the axle for launching.

You can spend 6k on a supercharger, but too cheap to buy a drive line to support it and bandaid the 8.8.

 

[sholzer]

i'd guess that most people that frequent this forum (corner carvers) would probably rather spend 6K on suspension components over a supercharger

Yep. Pretty much how I think... Corner carvers know how to drive and use that amazing newfangled thing called a steering wheel.

Now that friendly "In Yo Face" out of the way... I would rather drop $6k in suspension before a supercharger for the obvious reason... Getting constant power on the track for longer periods always beats power improvements...

As for the Watts... I am eyeball'n. I miss my SCCA build back in the late 80's where I took an 89 Ford ranger and built it up. It destroyed most vehicles on the street... Yes, I was young and dumb like we all have been... Now I live in earshot of the Seattle Raceway and plan to play in 2015 after I build this S197 up...

I've replaced everything except the upper control arm on my suspension, and won't even consider adding a supercharger.

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.

 

[ArizonaGT]

Billet parts are for Waxers, just get the functionality and performance correct and the track dogs will be pleased.

 

[BMR Tech]

Well, I agree somewhat.....but, it's hard to argue our other design we made up, compared to this one, in terms of strength.

That said - I don't think the strength will be an issue.

Trust me, the "track dogs" will be pleased with what we are, and will be bringing to the table. Fortunately, they will like the price point too - as we are taking our stream lined manufacturing process, and making it "work" for the community.

You guys have a lot of threads about many new things. I want I want now....

 

[Swine]

Bump for wanting it now.

 

[fhlh]

Clears wider tires, eliminates need for Sway Bar Relocation Brackets.

.... coulda used this years ago
Hate that I cut off the stock location perches.

 

[ArizonaGT]

Also you may want to consider a smaller bar (option, or additional forward hole on existing bar) that would make the bar softer than a stock GT rear bar.

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.

As far as the ability to make this specific bar reach a softer than GT rate - it's quite difficult. We have to choose a range, for product design and packaging purpose....so we chose to go "stiff"

That being said, if someone doesn't want the rates available with this bar - there are already so many options available, including a used OEM Take-Off:

Ford 20mm Solid (2005-2010 GT): 96 lbs/in
Ford 22mm Solid (2011+ V-6 standard): 146 lbs/in
Ford 24mm Solid (2011+ 5.0, GT500): 193 lbs/in
Ford 25mm Solid (Boss 302): 250 lbs/in
Ford 26mm Solid (Boss 302 Laguna Seca): 275 lbs/in

When making this bar, we looked at the available options closely.

We did not feel it to be appropriate, to make a $300~ sway bar that features rates of so many other pieces available, so we started the softest setting at roughly the rate of the Boss LS.

To add - we have actually lengthened the lever arms a little....so the rates I posted are a little on the higher side. The softest setting will be a little closer to the 11+ GT rate now.

I hope to have the updated rates soon, to share.

 

[BMR Tech]

Actually, here are the updated rates for our new rear bar:

Position 1: 224lb/in
Position 2: 259lb/in
Position 3: 302lb/in
Position 4: 356lb/in

SB042 Hole 1 rear 1.000 0.219 10.88 39.00 0.562 224.0
SB042 Hole 2 rear 1.000 0.219 10.13 39.00 0.562 259.0
SB042 Hole 3 rear 1.000 0.219 9.38 39.00 0.562 302.0
SB042 Hole 4 rear 1.000 0.219 8.63 39.00 0.562 356.0

Do I sense a little Fred Puhn math, Kelly?

I think you do, Norm.

You are one smart fella.

Of course, one must take into account Motion, and bushing deflection, etc.

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.

I say it is sufficient. I don't consider it any different than coil spring rates, with outside factors playing a role in their working (bonded bushings, etc) - or plotting for roll stiffness, without considering control arm bushing operation, and on and on.

I consider it similar to using an SAE factor on a DynoJet. That is the most common horsepower comparison among our hobby, but, factored #'s do not represent the actual (uncorrected) power output.

Nonetheless, our new sway bar rates will work extremely well with our new spring rates. I hope we can get everything "released" very soon.
