Do not buy the traction arm, that is not where you want to try and adjust toe from. That is not where the oem suspension adjusts for toe and for good reason. Those traction/toe arms are in fact radiaus rods (look it up in the shop manuel). You'll effect caster before you change toe. To adjust your rear toe buy the enlarge toe cam bolts from SPC, theyir just $45 and they replace the oem toe cam bolts, adjusting toe from where your supposed to do it.

 

why would you adjust the toe? if its within spec... dont mess with it. Toe should only be adjusted in case you are all out racing... not everyday dirving.

I would rather adjust camber for everyday driving before i would adjust toe.

 

As you adjust more and more for camber control, it moves your toe adjustments. Toe is a critical element to maintaining the behavior of these cars as you drive closer to the handling limits. It will make the difference between "oh gee here comes the rear end again" to yeeeeeeeeeeeeeeeee haw". I ignored it and turned a beautiful setup into awefull at the limt misbehaving. Now, it's right where it should be, flawless at limit behavor.
