Hi. just had my 06 tl auto drop with aspec suspension today and got it align at firestone. here is the info
front left
camber -0.6
caster 2.9
toe 0.02

front right
camber -0.5
caster 3.1
toe 0.00

rear left
camber -1.6
toe 0.04

rear right
camber -1.6
toe 0.07
do I need a camber kit? i have some ps2 tires on and those cost me a grip of money so I hate to see it wear like crazy due to this.
input?
thanks

 

doubt it... check top of thread there is a sticky a wholeeeeee article about this your only .1 outa spec which is fine

 

thanks I looked at the thread above, but I just like to make sure since my ps2 cost alot of money. Im just hoping for even tire wear...

 

Im in the same bout as you right now. I also have asepc suspension my camber is bit worse. I believe the right rear is -2.0 and left rear is -1.8. I never got a camber kit and just rotate them about every 6k.

 

Any setting outside the factory range will create more wear on the inside, albeit minor. Rotating won't stop the wear, but will only equal the uneven wear over all 4 tires. If you want it perfect, keep it inside factory tolerance. Might as well do it right even though it is minor and if the suspension should settle down farther, the camber will be negatively compromised.

 

Actually, the rear camber limit for the A-spec is about -1.8* so the camber is still in spec. Same for the front. No need for a camber kit.

I'll sell you mine if you really want it though. I bought the camber kit thinking I might need it. But my A-Spec camber has been hovering around -1.6 and -1.7 for the rears since I put it on 2 summers ago.

 

^Even though -1.8 is still technically within spec...it's at the edge and accelerated inside tread wear will still occur as Turbo stated. Mines at that, and the inside tread of my rears are toast...I'm getting an adjustable link kit....way cheaper than tires.

 

my back is at -1.9 and -2.0 and I don't have a camber kit. And I also didn't have any problems with uneven tire ware. I also put on 40 000km with these tires and so far so good.

 

Give it time. With 24,000 miles on the tires and even if they have been rotated, look closely at the tread and I'd venture to say that the inside is less than the outside tread, especially with that negative camber.

 

I'm still trying to figure out how added weight to the trunk affects toe etc.

My camber was out after I added the Comptech springs so I added the camber kit and had it aligned. All was fine the first summer but this year I experienced inner tire wear on the rear. The only difference was this year the car only went on a lot of trips with a loaded trunk. Abet 1/2 he miles. I had the alignment rechecked and all in spec. Note the rear camber was set very close to minimum spec ( vertical).

I know if you change the camber it changes the toe.

 

Additional weight in the trunk will change the camber slightly to more negative and affect inner rear tire wear. If the wear is smooth, camber, but if tread is feathered toe.
Put a vertical level on the outside of the rear tire, load up the trunk and/or put a couple of people in the back and watch the tire/wheel angle change. As the body lowers, the camber becomes more negative and will also change the toe slightly.

 

Yeep I know all that but when the camber changes to more negative where does the toe go? More toed in or out? I know its toe because of the inner feathereing.

 

If it's the inner tread, I'd say it's got to be a toe out condition, conversely if it were a toe in problem, the outer part of the tire would be feathering.

 

You may be right, but I haven't really measured thread depth, just speaking from visual inspection. I can't notice anything. And this thread ware doesn't really bother me as i drive 5 months a year on winter tires, so 1 set of summer tires can last me for years.
