Front Camber Kits to fix feathering..
I've been looking at camber kits in order to fix the feathering issue, I figure paying the couple hundred now will save me that much money in tires later.. So I was thinking would the Cusco A-Arms work? These are the specs according to the wiki at another 350z site which it wouldn't allow me to post the name of: +.5 Deg to -1.5 Deg ?

Heel toe feathering bacame an issue in the early 90's when directional treads began as a marketing device to sell tires. Marketeers found out that directional tires perfomed a tiny bit better in wet conditions while the tread was near brand new and owners were not likely to spend money demounting and flipping tires to rotate them, so they wore out much sooner due to the inability to reverse scrub the heel toe feather of the tread blocks.
The heel toe is much like the effect on shoe heels from pointenated leg bones which creates a caster like effect. The higher the caster the more severe the heel toe effect becomes.
When BMW like performance became desirable in the early 90's Nissan added higher Caster to emulate.
The combination of high caster and increased camber in turning [when you steer] creates most problems the higher the turn andle the more negative camber gain you get.
Toe can add additional stress on the flimsey tire block attachment which is not stress relieved by sipes on performance tires.
We have been dealing with these problems on Q and 300zx since 1990 when direction tires are used..............why the Q used a non directional oem Michelin which wore to the core in 15,000 miles but never feathered because they were rotated every 3,750.
You can change things with toe but not eliminate the problem with directional tires.
Use Michelin PS2 or other non directionals and rotate side to side frequently.

In the rear, the catch is, you have a limited range it can do. And when you dial out negitive camber in the rear, you take away some of the toe control that you dialed in. So when you use aftermarket rear camber arms, you generally need to add in a aftermarket rear toe control system because you need greater toe range because of taking out more negitive camber. Also notice that thier is no such thing as a front aftermarket toe control system other then some parts geared towards the drifting crowd for serving up greater steering angles.

This type of feathering has been seen much more often on trucks:
