Greetings. I own a '05 Neon SXT that has +2 deg camber on the DR, and -2 deg camber on the PR.
I'm wondering if it's possible to adjust/make it adjustable since it wears the edge of my tires.

Any assistance is appreciated.

 

The Dealer Tech was able to perform a 4 wheel alignment back in 01, on the 2000 Neon I was considering buying from them. It's rear tires were also worn as yours & on the freeway it had a moderate drift to the right, so needed constant left steering correction. His alignment guru put things right with the rear alignment & two new tires fixed that puppy up just fine since. No more abnormal wear.

EDIT: Welcome to the 2nd Gen Neon forum.

 

hard to say without seeing the alignment printout or being there to inspect the car.
if no parts are worn...you can get a camber adjustment bolt kit that will allow you to adjust the camber.
