Small update.
Took the car in to work last night and I'm quite sure the car went into tripod mode as I transitioned from the road to the driveway. (Inside rear wheel off the ground).
This is pretty telling of the rigidity of the S550 monocoque.
Some will hate a car this rigid but for me it's absolutely AWESOME!

Also, now that I've driven the car in a heap of different scenarios, I can confidently say that the caster effect of the front wheels is MUCH more pronounced with the sway bars fitted. The steering wheel just SNAPS back to centre when you let it go. Anyone who's spent any amount of time on opposite lock will instantly recognise what this means in terms of steering feel and predictability.

I've even tried severely abrupt changes in direction just to see what happens. There is NO delay in the car's reaction time, it just instantly heads where the wheel is pointed without any roll or even a hint of complaint from the car. Not a single complaint to be had. :thumbsup:

I have the BMR swaybar kit as well. Car feels much better with it than without it that's for sure. Roll and float are nearly gone. Installing the front bar is a little more work but totally worth it. Next item to go on the car when my buddys lift becomes free is Ford Competition track struts and shocks and BMR rear handling springs. Can wait to hit the turns with those on the car.

I would love to hear how your car turned out after the install! I will have practically the same mods as you but i also have bmr lowering spring in the front (performance)... any issues clearing the front bmr sway bar on bumps or issues with your sway bar end links?

I actually now have BMR performance springs front and rear, swaybars and the FC track dampers. As well as the normal IRS bits ie endlinks, cradle lockout kit. Recently added nitto 555r drag radials and holy shit is my car so much more fun. The combo of parts has it feeling like it on rails but not harsh at all. Rear tires are taller than normal 305 35 20 but so far no rubbing at all. No issues with clearance with the endlinks or swaybars

Hi, I am liking the sound of springs, sway bars & cradle lock out. I currently have lowering springs and will get the other two suggestions.
I am seeing a reasonable deal on white line sway bars. Can I assume that these are a good product I haven't read anything to the contrary ? I will also go with the bmr lock out kit.
Also I am not that handy or have a workshop, a recommendation to installation would be appreciated? I live in Sutherland shire Sydney.
Thank you for any help.

Hi John, there’s nothing wrong with the Whiteline bars as such. The real trick is getting the bars set-up how you like them (more/less over/under steer basically).
The cradle lockout really should be a first mod for anyone wanting to tighten the feel of the car.
@msweet might be able to help for an installer in your area,

Sway bar-only swaps interest me. I'd like to see a list of S550 factory and aftermarket sway bars, with their dimensions and ratings, so real comparisons can be made.. My search skills haven't yielded much assistance. Any help out there? Mine is a 2010 EB PP1.

===============================

Here's something, although it seems to be from the S197 era:

GT 24mm - CR33 5A771 A
Boss 25mm - CR33 5A771 D
Boss LS 26mm - CR33 5A771 E

==============
CR3Z-5A772-A: GT RSB $160.57
CR3Z-5A772-D: Boss 302 RSB $201.72
CR3Z-5A772-E: Laguna RSB $203.82
(BAR - STABILIZER
Make: Ford | New Part#: CR3Z5A772L)

Increase in weight = 8.9%
increase in roll rate = 17.6%

Spring rates in lbs / in. - best info i can find.

Stock GT 136 front / 142 rear (245 tires all around)
Brembo pkg 131 Front / 167 Rear (255 tires all around)
Boss 302 148 Front / 186 Rear (255 front 285 std. compound rear)
Boss 302 Laguna Seca 137 Front / 191 Rear (255 front 285 rear tire, corsa compound)

Steeda Sport 200 Front / 175 Rear.. - future = 275 front 305 rear.

=====================================
I'm not giving up, yet.

More (seems like S197 also):
====================================

I got this from Sam Strano's site. He sells whiteline, but didn't list the stiffness of them. Might not have the data...
Can Whiteline and BMR and others pipe in here? Maybe stuff like this can be posted in a sticky...

Sam, I hope it's ok to publish this from your site.
Comparison vs. Ford OEM:

FRONT:
Strano Performance 35mm hollow: 472, 547, 642 lbs/in
Ford 34mm hollow (2005-2010 GT): 385 lbs/in
Ford 34.6mm hollow (2011+ GT, Brembo, Boss): 436 lbs/in

REAR:
Strano Performance Parts 8419 1" tubular: 162, 185, 225 lbs/in
Ford 20mm Solid (2005-2010 GT): 96 lbs/in
Ford 22mm Solid (2011+ V-6 standard): 147 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


...
The BMR-SB023 Rear Sway-Bar is: 146lbs/in

The BMR-SB022 Front Sway-Bar is: 441lbs/in - 506lbs/in - 587lbs/in

I am curious to know the dimensions of the Strano Front bar. Ours is 35mm....with a wall thickness of .219". The lever arms (torsion bars) are 13", 14" and 15" in length.So...what's the range of the Whiteline and others?

...

My bar is stiffer.... I use a .250" wall on front. Rear bar I use a .156" wall. Both are 3-way adjustable.

FWIW, we've tested the Brembo and non-Brembo V8 GT springs. They are so close that they are not worth considering the difference.

The springs are progressive, so the measurement at ride height is:
Non-Brembo are 110 F / 154 R
Brembo are 125 F / 188 R
-----------------------

BMR rear sway bar Specs:

OH....and the rates, at this point:

Hole 1 - 272 (Laguna Seca-ish)
Hole 2 - 319
Hole 3 - 378
Hole 4 - 457

Ford 20mm Solid (2005-2010 GT): 96 lbs/in

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

Position 1: 224lb/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 4 rear 1.000 0.219 8.63 39.00 0.562 356.0

Here is a quick run down of the rates we settled on, after testing. They will all be available as front or rear pairs, separate. Of course, we will have "kits" with all (4) springs for handling, performance, and Drag.
