He understands what I was pointing out, and why the backend is behaving the way it is. When he returns to Aus. he's going to have his head of R&D call me so we can discuss the model and testing further.

That's cool. As much fun as you guys have... I wish I had your job!

If so, any guesses as to how long it will be before we can get adjustable front and rear bars (e.g. Whiteline?)

We have front and rear adjustable bars in stock right now! 25mm front, 22mm rear.

F/U question, will I need endlinks or are the stockers good to go.

[Harman Motive]

We put the whiteline sphericals on the front for good measure, but the stock fronts will work. Our autocross tester is still on the stock links with no problem, even after multiple events.

Nice... I'd love to see a review of these (Go for it Gil!)

[Harman Motive]

We are just now installing these on kaz' car and Im sure he will post follow up, although there quite a few other suspension mods that went on at the same time.

Theres also a review of the front bar here:

We currently have some of their 20mm rear non adjustable bars in stock and ready to ship. The bar sizes are smaller than the previous year's bars, but due to the design of the rear suspension and in our testing, they do not seem to need to be as large.

will 20mm in front and 22mm in rear work for occasional trackdays or should i go 20mm both front and rear. thanks

I'm going to guess that you're referring to the rear toe-in on compression that you mention in the rear camber adjustment thread...

Installing adjustable Perrin front and rear bars right now. Both 22mm for a rotation-happy car, but we'll see if it works.

I was thinking the same thing.

Be aware, this car is not nearly as rotation happy under throttle as the old car. many people will equate this to understeer, but that is simply not the case as there is so much grip to be had in the front. With an overly stiff suspension, one would be able to get the rear end to come around with liberal throttle application, but that would not be fast on a track or livable on the street.

We were talking about the toe in on compression we mentioned in the other thread. We have a potential adjustment for this that we are going to model starting Tuesday or so. We may have a pretty simple fix that should really transform the handling of the car.

Oh yeah....did we mention we talked to Whiteline about the release of the Black Box when they stopped by last week? Very interesting. Hopefully we will have a tester in the near future to try out and give our impressions of. This thing could really transform suspension tuning much in the same way stand alone ECU's transform engine tuning.

"...so much grip to be had in the front" - I assume you mean rear? I definitely experienced some throttle-induced rear-end movement at very low speed, but I was trying to get the car to do it. I was thinking more in terms of balance: which end breaks away first under neutral or "maintenance" throttle, as on a skid pad or when holding a line through a constant-radius corner.

Definitely eager to hear more about this...

I agree on this and said so in another thread. Do you know if it allows remapping of the DCCD as well as the VDC? That would be huge.

I mean the front. There is a ton more grip in the front compared with the old car due to the revised geometry (very similiar to old, but with more caster) and much wider track width. Once you start to mess with the camber settings up front it becomes apparent how much grip there is to be had. On track, with my current settings, the car is very neutral with no understeer if driven correctly. Equating these setting to the older chasis, the car would be quite tail happy under power, which is the difference between the two.

Not sure yet.
