Help Guys!
Just had the car in for a service and the mechanic directs me to the front of the car for a look at the inside edge of the tyres. Where he tells me that my tyres are screwed.
The tyres are 235/35/ZR19 and the car has been lowered ?inches (Bilstien TRD) by the previous owner (somewhere in japan).
The car has only done about 10,000km. The wear is ONLY ON THE INSIDE EDGE and after visiting a tyre place I'm told the car LOOKS to have to much camber. After a laser alignment, theres only about 2-degrees negative camber and already adjusted back as far as it will go. The blokes just scratched there head head and said, 2 knew tyres mate! Should I try to get hold a camber kit? Tyres are killing me at $300 a hit.

Hey, I know how it feels to eat tyres due to camber. My celsior is really really low, with more than 2 degrees at the front and my tyre wear is fine, its not perfect but not far off it. What you really need to do is just find a good experienced guy to align your car. I dont know that much about alignment but I know that the place I used to go to just setup the alignment for a stock celsior which obviously was terrible. I ate through tyres with it like this. Then I tried another alignment place and met an older guy who had been aligning cars for years, he used the stock settings as a guide and then setup the alignment using his experience. It now drives straight and doesnt eat tyres even with alot of camber. I go through all of this because I like my car savagely low, if you dont mind being raised then I guess thats the easiest way around it.

If you have plenty of negative camber then either you are wearing the inside edges or else you have significant roll camber-change in your suspension, or possibly your settings are not what you have been told they are. There is no magic which allows a high camber setup to wear evenly otherwise. I have a small amount of negative camber at the front but my tyres wear on both shoulders because I keep burying the car through roundabouts. Simple.

Was it the front or the rears that were stuffed? The rears will camber in when you get on the loud pedal, and wear rapidly especially if you lose traction.

Most Soarers will not hold acceleration squat for long, especially in normal driving. Of course Braden is right that losing traction during a fast takeoff will wear the insides faster but I counted that as a bit more than being "on the loud pedal" so thought the effect would be negligible. Some toe-in will be a more consistent effect during acceleration but does not matter.
This raises something I do not recall reading anywhere. Does the Soarer have anti-dive or anti-squat geometry in the suspension?

Hey guys, thanks the replies. The tyre wear issue is only on the front tyres. The rear tyres are running a a lot more camber than the front and are wearing perfectly even. I didn't realise that 2 degrees was to much, as a lot of my previous rides have been commodore's which had been drastically lowered with wide tyres, running as much 3-3.5degrees of negative camber without to much uneven tyre wear. Could this be due to the Soarer using a double wishbone setup unlike the commo's MacPherson strut arangement?
