as a new convert, I am building the RDX, and have a couple of questions
Do i need different (shorter) camber links? With the dayger setup its already screwed all the way in and I havent even put it on the board??
where are the 2mm spacers listed as "shims under coupler" on the front..i am asuming between the bulkhead and the hignepin (roll centre mount)??
Also, what are the position of these roll centre blocks on the dayger setup??
2,3 seem circles, so is it lower hole with the dot on the roll block to the top?
.

The stock camber links should be ok, but using rpm ball cups you have to trim them a little to get negative camber on your shortest camber link position.
As for the 2 - 1mm shims under the couplers that is referring to shims to be placed between the bulk head and the roll center blocks to widen the front end.

Are there low AND ultra low roll centre blocks??....crap i just ordered 8 of the low ones.
edit: 79121 are the low ones...all this talk of ultra is confusing

There are only 2. I am not sure how the "Ultra Low" got associated with the part, it even says "Low Roll" on the package. Only because it is "Ultra Low" in relation to everything else I guess.

Hey Jeff,
I have seen a few people using round stickers that cover up the works of their RDX diffs to keep the dirt and grit out. Seems to work very well.
How about your suggesting to Corally that they make a bigger LW Pulley Snapring (#79172) that would do the same thing? Would be great for outdoor.

So what is the theory behind using the low roll centers on carpet with foams.
My understanding of what a lower roll center does it actually move the roll center lower then the CG giving it even more roll and thus even more traction. Right?
Is the lower roll centers maybe easier to get your ride height? thats the only other thing I can think of. Or maybe the 2nd position on the low roll centers is inbetween the 1 and 2 position on the regular roll centers?
Just trying to understand the theory on why these lower roll centers were needed and why just mainly for foam carpet, I mean foam has way more traction that rubber, so I would of though the opposite that people would want them for rubber(Carpet) for even more traction

Woody, roll center is a function of roll stiffness. The lower the roll center, the lower the roll stiffness. This basically means that with a lower roll center, the car will have more roll, but the key is, it will roll slower and smoother. This is the main reason why it is used on carpet/foam because the car will stay more composed in the corner and carry more speed when the car isn't laterally jerked into the corner like a high roll center would produce. You do get more traction because of the increased magnitude of the roll, but it doesn't scrub speed because of the nature of the roll. If you have any more questions I can explain it in even deeper vehicle dynamics terms, but I think that covered it.
One other thing about roll centers: A high roll center will roll less, but quicker. This is understood. However, soon after the car reaches it's max roll point, it overloads the tire and creates less traction. You can test this by running a more angled (lower holes for camber link on tower) camber link versus a parallel one in the front. The angled link will turn-in harder, but will not have as much steering in the middle and exit of the corner. The parallel link is the opposite.

So I'm looking at some of the Nocak race setups and on the front arms lower shock mount is all the way to the outside, problem is my tires rub the shock perch and spring if I set my shocks this way, I have to run mine in the middle or inner hole, can I merely move the top shock mount in 1 or 2 to get the same "effect" (or close to it), or am I all messed up and have to shave the inside of my foams? ...does anyone else have this problem? Also I only have the standard extension chingaderas for the rear, so I would go up 1 spring from the setups right?

Just reduce your EPA until your tires do not hit. Have you gotten the "Long" rear brackets yet? Do you have the black spring kit? If so, we can work on some stuff this weekend.
