Hi Cal,
I've been busy with the s2ki conversion so my reply isn't gonna be a essay lengthed one, but if there are specific questions that you want answers to I or my suspension guy (who designed these for me on my car) can answer for you.

1-
The arm accomplishes the reduction in rear toe change by moving the pickup point where the rear control arm connects to the knuckle. We measured and confirmed the numbers at multiple ride heights. And of course they have been driven to test them too.

2-
It is highly suspected (tho not confirmed) that the only real change of the 04 knuckle is the moving of this pickup point.

Yes both items are intended to do the same thing, and go about it in very similar ways.

Please let me know if you have any more questions. I have been running the proto-type version of this part on my Race S2K for some time now.

Is this needed in '04s?

Sorry, but I'm not a car mechanic and I don't understand all of this, but I'm always up for improving the handling of the car.

 

Hi Ry,

Thanks for the reply.

It seems that "your" approach has the real advantage(over what Honda has done) of allowing for the independent adjustment of toe and camber. Honda has inproved the geometry but does not allow for independent adjustment.

With regard to your new arm, is the toe adjustment accomplished at that point where I see a "tapered" section on the attachment bolt?

What toe in do you like at the track?

Regards, Cal
