today i had alightment for my completely stock AP1 , and here is the print out reuslt :
left right
front caster 3.4 4.5
camber -1.7 -2.0
toe -0.9mm -0.9mm

rear camber -2.5 -2.6
toe 0 0

i ask the guy who did it , and he said this is all good and no problem , but because of the language problem , i am not able to understand why the right and left is different !! so do you think this is ok ? or i better have them adjust to the same ?

also toe -0.9mm , is it mean toe out 0.9mm ?

 

Looks like the guy did a very half-assed job. Your front left and right camber doesn't match and you have front toe in and no rear toe in. He said it was good because it's probably still within Honda spec (although I doubt it with that much rear camber) but either way I wouldn't trust him ever again.

Find someone else at a peformance oriented/race car setup shop to re-do it. If you street drive I'd probably reccomend a bit less camber if you autocross I'd say 1.7 front and 2.25 rear is good. You probably want 0 front toe and some rear toe in.

 

yes , i am autocross in the S . in fact , i told the guy get more camber as much as possible also the toe 0 in the rear , but of course i told him the right and left have to be the same , but i guess he don't understand !!

i just read something in the forum , the caster can be 5.5 up ?? is it true ?

and the front toe -0.9mm mean toe in 0.9mm ?i just not sure the reading mean !!

i plan to do it again after 2-3 day ,get a little toe out in the front or may be let it be toe 0 , and again try to get more caster .pobably let the rear stay same , cause it is only 0.1 different in the camber !!

thanks CosmosMpower !!

 

search for "uk alignment". start from there and customize to your needs. sorry i'm to lazy to link you. think specs are

ft left & rt camber = -1
ft lt & rt caster = 6.5 deg
ft lt & rt toe = 0

rr lt & rt toe in = .16mm
rr lt & rt camber = -2

 

Negative toe means toe out. Also, with no toe in the rear, I would expect your car to be slightly tail happy.

 

so my front is actually toe out now ? i am confuse now , cause CosmosMpower said it is a toe in !?

i think i better let it toe 0 , although i intent toe out at the front , but i don't want to tear the tire too much and i still don't know if it is toe out !!

 

Stumbled on this thread by acident, but here is a typical 'fast road' setup we run in the UK. This is not the Honda standard but I use something similar and its performance gains in every department.

Look at the reduced front Castor, increased rear Camber and neutral front toe.
Any serious toe out at the rear may well kill you, be carefull!

It's a sign convention, and different people do it differently. So unless you say "in" or "out" nobody really knows whether + is out or + is in.

But I assume your rears are toed in.

Camber is more regularized -- negative is always with the top of the tire angling into the body of the car.

 

thank for helping !!

i really have doublt on the number , so different alightment shop may have a different reading in " + " or " - " , right !?

i have no experiecne adjust the caster and toe before , but i read a lot about it in these day .

my caster before the alightment was
left 4.9
right 6.0

i ask the guy to get me more caster toward the back , and now the caster is
left 3.4
right 4.5

and i can clearly feel the different when i braking or accelerate in a U turn . the steering feel lighter and easier to turn in , feel better , so i guess this is the what is the gain by the caster , right !?

i was confuse , becasue what i read is likely bigger number mean more caster , sample if i increase the caster , it should be 6.0+(6.4) . but why mine go to a smaller number now !

i just guess the guy who did the job for me , he did give me more caster , because if it is not the steering should be heavier in turn than before , right !?

anyway i will go to the shop tomorrow again , and ask him to re-alight it , heard that the caster should be the same at both side , and also adjust the front toe 0 to aviod misunderstand , if no gain in performance , at least save me some tire!!

 

Yeah. Just say "in" or "out" when you tell them what you want for toe.

For camber you can say "+" or "-" because everybody does that the same.
