Default End to all speculation: The CSL Kingpin

So I decided to see what the differences were...

Casting is the same, even same numbers on the back..

I think terra was the one who called it....

CASTER!!!

The strut mounting is drilled slightly offset, compared to stock, which is centered. Not sure how much it affects it yet, but we'll find out soon!

Would it have anything to do with the fact that CSL uses different steering ratio? Just curious..

Pics still are not working for me! Try photobucket!

How do you host pics from flickr without them showing up as black boxes?

Nah, It's to gain caster and there is no way of doing that at the strut tower.. This is in lieu of a caster/camber plate lol

Every time I edit it, I have to uncheck "automatically embed media" and it works? lol

I honestly can't tell a difference.
I'm not sure that small change would affect caster, would it?
A camber / caster plate has a much bigger setting possible.
That looks like such a minimal change.

Could you weigh the two parts to see if they are identical please?

It takes more movement to get a change at the strut tower. When the change is at the wheel, the affect is greater. After all, we are probably only talking 1-2 degrees..

We did weigh them and they are identical. The casting is the same.. Numbering on the back is the same, except for the date code.

I doubt it. Otherwise the ZCP would have gotten the CSL kingpin.

Depending on which way the angle changed, the car will either become more stable at high speeds or more responsive at low. I think
