How do the new rear upper control arms make the car handle? I know it takes out some camber which makes me think the handling would be worse. After the control arms are replaced, do the tires just wear out from too much weight?

 

I wouldn't think it would handle worse. After the arms are replaced the tires shouldn't be wearing as bad on one side.
Tires do wear out faster I'd say when more weight is applied, but if your thinking the new arms weigh more than the old ones I would highly doubt it.

 

I'm thinking people probably put too much weight in their car.
