Nice set-up for STU. Not sure which tires you're running, but the pressures seem a tad high.

Anyone know what would be the max front negative camber legal on a B-Stock Evo X?

In stock class, all you can do is flip the camber bolts, so it'd be ~-2*

From the 2010 rules book.

"Both the front and rear suspension may be adjusted through their
designed range of adjustment by use of factory adjustment arrangements
or by taking advantage of inherent manufacturing tolerances.
This encompasses both alignment and ride height parameters if such
adjustments are provided by the stock components and specifi ed by
the factory as normal methods of adjustment. However, no suspension
part may be modified for the purpose of adjustment unless such
modifi cation is specifi cally authorized by the factory shop manual for
non-competition purposes."

So, if I read that write, the OEM EVO X Service Manual would have to advise techs on the flipping of the aforementioned bolt for it to be legal. Does it read like that, or is flipping the bolt a trick EVO guys figured out?

I don't know the Evo X, but for the IX, it's an eccentric bolt that can be rotated in two directions. It's within the "factory adjustment arrangements" and is legal for stock classing to use the setting that gives more negative camber. Hope that helps.

Does "flip" mean remove bolt and insert through the opposite side? Or do you mean to turn the bolt (ie rotate it within its current position).

By flipping what they really mean is to keep rotating. So on pre X Evos when the eccentric lobe (for lack of a better word) is on the extreme inner side you'll be around 0 camber, when it's pointing up or down you'll have around -1 camber, and when it's on the extreme outer side you'll have around -2 camber. I think that's how it works

Sneaky sneaky...

On my '03 Evo 8, there are only two settings for the eccentric bolt, in or out. Won't fit at any angle in between. Basically, the hole that it goes into is oval, and the bolt's cross section is oval as well. Only two orientations work, 180 degrees apart.

My Evo X has eccentric bolts in some places, so it's still adjustable from the factory.

However, when I took it for an alignment I found out it has limits to what it can do for you. I asked the mechanic for all the negative camber I could get at the front (within specs - up to 1.5deg - so shops would quit talking down to me about tire wear.)
After a couple of hours of fussing with it, the guy said he could only get me about -1.1 deg at the front before it messed up the toe.

Still, it was better than the original (lack of) alignment.

When I get back from the sandbox (next summer) I'm going to have a friend see if he can improve on the Goodyear guy's alignment.

Donny has skilz, and has a history of improving on uninspired alignment jobs for me.
