Front:
Toe-in: 0.07* (per side, 0.14 total)
Camber: -1* (per side, non-adjustable per the manual)
Caster: 4* (non-adjustable).

So does this mean that front caster can never be changed. It will always remain at 4? Until you get aftermarket suspension I suppose.

 

EDIT: Posted question in the main forum.

 

would these specs work on the evo 9 as well?

 

Can we throw the stock Advans' Rolling Diameter in the OP? Calculated from the 245/40R18 spec it comes to 25.72 in. Can someone confirm what the *actual* size is?

 

so what is the widest tire you can run on a stock MR rim?

 

Just completed a DIY aggressive X alignment. Here's the procedure and results:

Front:
Off with the wheel (13/16 deep six-point).
Pre-adjusted toe, 1-turn out (7/8 & 13mm opens)
Loosened both strut bolts and reversed top cam (19mm deep)
Jacked under the studs (wood block) to remove slop and tightened.
Result: -2.6deg left -2.8deg right 1/8" toe out. Good enough for now.

Rear:
Put a match mark at 12 o'clock on all four cam bolts. (Sharpie)
Loosened and rotated each cam 45 degrees in. (17mm deep & 17 open)
(rotating cam in pushes control arm out for more neg camber)
Result: -1.95 deg each side, 1/16" toe in. Good enough for now.

Got lucky with the toe results based on guessing. Where I used SAE tools it's because they fit better than the metrics. Measured camber with a 24" carpenter square, machinists rule and trigonometry. Measured total toe with a home-built trammel bar and machinists rule. Took me an hour.

FWIW -- Bill

My local shop has camber, toe & caster.
Any specs for the caster?

 

It's non adjustable on the Evo unless you have caster plates... so what you've got is what you get... unless you bend something.

Basically around 4.5 or so is stock.

 

What are the advantages/disadvantages of putting on wider tires than the stock ones?

For example, what are the advantages/disadvantages of replacing my stock 245/40/18s with 265/35/18s.

 

Great info, thanks for getting me going!!

 

Wow, this is good info to have. Thanks for writing this up!

 

I had my X on the alignment machine yesterday, and my front camber cannot go more positive than -1.8. I want to get the camber in spec to prevent tire wear but when I turn the cam, it starts going more negative to -2.5 and then gets stuck there. Going the other way does the same thing loll... Is it really possible to get in spec?

Thinking of badgering the dealership about this...

 

want to know that too! what is the best size tires to put on a stock rim?

 

245/40/18 (the stock size) is best.
