Contact XRay or head to the shop and get the right bearings.

Can you explain all that you know about roll centers?

Comments from anyone is welcomed...I remembered reading an article on it but I confused myself and did not really get it.


Any help would be greatly appreciated!
This is very hard to explain, but I'll try my best.

Ok, putting spacers under the camberlinks makes them at a higher angle as compared to where they are connected to the shock towers. This makes the car roll faster because it's roll center has been raised (someone correct me if I'm wrong about it being lowered or raised). This means that the car will shift to lean to its side in corners faster than if no spacers were added, going to whatever you have it's camber set to.

I hope this Kinda makes sense...just try to visualize it!

P.S. If anyone can clear this up or add to it, PLEASE DO!

Okay, I thought I understood the castor discussion, until I read the post about using 0 degree blocks with a one-way.

Now, I know this all depends on the track surface, but won't going from the stock (3 degree) blocks to the 0 degree blocks provide less steering mid corner? And since a one-way will provide more steering off power, how will you gain steering on exit (on power)? Isn't the rule of thumb, that less caster = less steering (with considerations for camber of course)?

Or, is it that since less caster = less steering, then it serves to "calm" the effects of a one-way?

Or is it...oh, look I've gone cross-eyed...
LOL

Any clarification would be appreciated.

Cheers.

Kaizen,

Keep in mind this is just my opinion and what I've experienced.

Less caster seems to make the car more aggressive during initial steering input i.e. more twitchy feeling. It also seems to give less overall steering, especially mid-corner and corner exit.

However, many people are finding with the Xray that the zero degree blocks (which are aluminum) are giving them more steering all around due to the fact they flex much less than the composite C- hubs.

If you are refering to raising the inner pivot point of the upper camber link (in relation to the outer), then you are "lowering" roll center. Lowering the inner pivot point creates a "higher" roll center.

In other words, you are correct about it being "raised" or a higher roll center.

Ah, I guess less flex will make the car more reactive?. That makes sense. Makes you wonder exactly what impact the cornering forces has on the stock carbon blocks. Flexing from 3 degrees to 0 degrees or perhaps more to get this result? In any event, I will have to try them out to see for myself.

Anyone experimenting with the 3 or 6 degree aluminum castor blocks? Even more steering throughout cornering range? Oversteer?

What's important is that they be consistent (i.e. same length) -- especially side to side. In other words, and for example, left front and right front have to be the same length. I think mine ended up being something like 62.5mm (front/back, side/side). But, don't quote me on that.

Wap, your problem has happened to many people, so check that the things that hold the spring onto the bottom of the shaft and make sure that they are pushed down all the way (forgot what they are called...haha).
