GT350 Front Sway Bar

[nastang87xx]

I have cortex and BMR. If your interested in the BMR end links I have 2 sets for the front and one set for the rear. All brand new. If interested I'll sell them for a good price. Pm me if interested.

I also have Brand new BMR rear lower control arm bearings and vertical links. All new never used.

Let me double check the rule book and do some further research. I'll let ya know.

I put the BMR front and rear sway bars with their end links on the other day. Out of all the suspension stuff I've done I believe these made the biggest difference.

34mm to 35mm is a >12% increase in stiffness.

Assuming the BMR has the same 5.7mm wall thickness, It's about a 30lb increase in roll resistance for the same length arm (hole position). (12" arms, 39" width) GT350: 34mm DIA x 5.7mm wall (1.34 x 0.22 in)

Not a huge change. It would be a slightly noticeable on track by a good driver. Since the bar has 3 adjustment holes, it would be nice to know how far spaced each hole is, which a difference in hole could be 15lbs each.

Just to add some further confusion, the owner's supplement for the 2015/2016 MY cars shows different rear sway bar specs than the owner's supplement for the 2017 MY cars:

2015-16 Rear stabilizer bar specs:

GT350 22.2mm DIA x 3.9mm wall (0.87 x 0.15 in)

GT350R 22.2mm DIA x 3.9mm wall (0.87 x 0.15 in ) with 8mm (0.31 in) shorter arms than GT350

2017 Rear stabilizer bar specs:

GT350 22.2mm DIA x 3.9mm wall (0.87 x 0.15 in)

GT350R 24mm DIA x 3.6mm wall (0.94 x 0.14 in ) with 8mm (0.31 in) shorter arms than GT350

I'll clear this all up because I went through all of this last year.
The GT350R has a larger diameter rear sway bar. The end link hole in the bar is in the same location as the non GT350R. All the GT350's and other mustangs use the exact same sway bar end links.

The GT350 and GT350R use the same front sway bar.
I have both the R and non R rear sway bars. The R is bigger in diameter.

Excellent! Thanks. The owner's manuals seem to be a bit of a work-in-progress.

My back of the envelope calculation says the larger diameter rear bar will be about 25% stiffer than the smaller bar when the arms are the same length.

It's a huge difference. I have the rear BMR bar on full soft and the front is on the middle hole.

The balance is fantastic.

That might be the ticket then. I don't want to screw with the rear bar though. Not yet.

 

[nastang87xx]

Links are not allowed, only the bar itself. Crap...I might end up having to kick myself to CAM-C. Index difference is only .007 though. Might just wait and see how I do come the first two events.

In street you are allowed to change one bar and the corresponding attachment hardware. Also keep in mind that aftermarket bars are ADJUSTABLE.

I thought it was only the bar itself. I'll check again. I hate how the rules are presented in SCCA. It's not very clear.

13.7A

"Substitution, addition, or removal of a single anti-roll bar and supporting
hardware (brackets, endlinks, bushings, etc.) is permitted. The use of any
bushing material is permitted. A bushing may be implemented as a bear-
ing."

Perfect, thanks!
