new whiteline sway bar kit for ek

[spacepants_fb]

Thank you Mr Ben la!

[spacepants_fb]

Just realised that there's a typo in the title. Can the mod's fix please? (whiteline vs whitline)

[CTR Coupe]

I hope whiteline addresses this asap... perhaps a solid link with 2 holes at the rear will be good

yep a solid block behind the rear would be perfect.
i might even look into upgrading to the new brace depending on price/compatibility with what i have now.

G'day everyone,

Thank you for your feedback on the prototype new swaybar kit. We're comfortable with the design as it stands now but will take a look at some of the suggestions made and come back to you.

In the meantime, we wanted to explain the reasoning behind this particular design to help understand our position;

- In our view, one for the major reasons behind failure of our previous design was not re-torquing of mounting hardware as indicated in the instructions. We are not trying to wash our hands of the problem but we can't ignore the fact that our own R & D test car did not have any problem after many hard kilometres on and off the track. However, we did have experience with a customers car that was showing signs of metal fatigue and had not been re-torqued. This is not a "splitting hairs" issue as any design that works around laminating or bolting to existing pressed metal must be re-torqued. The instructions for the new design make an even greater point of this and we also provide torque settings.

- We looked at other designs in the market and tried to combine the strengths of other peoples experience with our own. We found that there was no single brace/mount hybrid that also laminated the OE sheet metal at the mount point. Our research also showed that a popular laminating design did not use a single piece brace/mount like ours. Other designs also modify the pickup points, swaybar needed and resulting geometry. This is something we wanted to avoid. Our view is that the single piece aspect is more important and the load distributing washers used coupled with the control arm pickup mounting and the use of Grade 12 and 8 bolts is more than adequate.

- The mounting kit however also had to meet certain cost targets to keep the price affordable which instantly ruled out the use of alloys. The relatively lightweight steel brace design with twist beam box centre is strong yet light. This design also importantly maintains all original OEM mounting and pickup points meaning the brace alone can be used with other swaybars including OEM while also ensuring that the swaybar geometry, motion ratio, angular change and performance are not compromised.

No, it is not like anyone else's design but we are confident that it will do the job as good or better than any other design as long as it is correctly fitted.

Happy to answer any further questions you may have.

Cheers

Interesting response Jim.

Can you please explain this point a little bit more?

What exactly do you mean by the term 'laminated'? Any point where the brace meets the OEM metal?

[Whiteline]

G'day Zdster,

I guess you could also refer to it as "sandwiching" between materials. We're referring to laminating or sandwiching the OEM metal cross member between new component parts.

Our brace attach's to the rear of the cross-member (as seen from the rear) via tubes and hardware using existing holes and the control arm inner locating point. We supply washers for the bolts that mount to the cross-member though the control arm pivot bolts and single brace design do most of the work.

The only aftermarket design that we found that actually laminated the OE sheet metal between 2 new pieces of metal does not use a single brace/mount assembly but rather 2x separate mounts.

Hope that clarifies it.

Best
Jim

ok i have a few questions regarding price.

1. how much is this total kit (sway + brace)
2. how much is the brace alone (for people already with a sway)
3. will this fit other swaybars such as those of EK9 ?

It doesn't matter if it is thicker than the ASR or not. It depends on the material it is made with and the shape/cross section of the plate. Failure does not always occur in the plane in which the load/torque/moment is applied.

failure seems to apply to the weakest point in a plane - this place seems to be the swaybar mount to the subframe.
Therefore the mount itself , and the space behind it must take more / most load. By dispersing the load across a larger area ( IE ASR / new whiteline) and also needs some sort of anti-plucking reinforcement behind the swaybar mounting. The ASR kit and Beaks kit utilise this - they link the 2 mount bolts with a single larger piece of metal. Helps !

i already got a whiteline rear sway bar,so do i jus buy the brace or i hv to buy the whole kit again. cheers

what is going to happen to customers that alraedy has teh sway?
r they able to get it done free of charge? or at a cheaper price?

[Whiteline]

G'day,

bennjamin,

While there is a small horizontal vector acting on the swaybar chassis pivot point, which is then transferred through the mounting bracket onto the chassis, by-far the major force is in the vertical plane which is distributed by both M10 Gr12.8 control arm pivot bolts and four M8 Gr8.8 chassis mounting bolts.

In our view and experience, the magnitude of the horizontal force is within the strength of the chassis mounting face, as have not seen M8 bolts with large backing washers to 'pluck' out of the chassis even with our two piece bracket design - provided bushes are properly lubricated with minimal rotational resistance increasing torque effect on the bracket and all fasteners are correctly torqued up at all times - so I certainly cannot see this happening with our new single bracket design.

Again, we are happy with our new single piece bracket design, and while there may be some merit to having some form of lamination, this really applies to two seperate piece bracket designs where there is no load sharing and re-distribution onto both sides of the chassis.


ccibai and |N|,

We have deliberately maintained all original chassis mounting points and swaybar pivot mounts (in all three x, y and z planes) as for OEM swaybar and bracket, so that the single piece bracket alone can be installed and used with all our immediately previous design swaybars as well as OEM swaybars or other direct replacement bars.


As always, thank you for your feedback and suggestions, and happy to answer any questions.

Cheers,
