07 g35s sedan - best option to alter caster

[ADiamond75]

SO here's the deal. I seem to consistently wear out front tires on the outside on the front of my car. It is a problem I have in all my cars. Over the years I have figured out that this comes from corning hard consistently. On every car I've ha I solve this by increasing the caster. I took my first look at the front suspension on my g35 today and basically figured it has to be an upper front arm that needs to be replaced with an adjustable arm to adjust the caster. So my questions to you the community are:

1) Is the Front Upper Control Arm the proper way to alter the caster
2) What options are available
3) What have you guys used, are using and how do you rate the product

Thanks in advance.

The upper control arms controls camber. If you go after market, you can control caster & camber with the Eibach kit. Normally just adjusting the camber & toe properly will get you the alignment specs you need.
