It's better than stock... optimized factory settings if you will.
But your better off spending the money on adjustable gear that allows you to customize your settings based on your preferences and/or purpose of the car (street/track).
Use offset bushes instead, whiteline has a good catalog of bushes that make the stock components adjustable.
Would recommend their adjustable front & rear swaybars while your there, they made the biggest difference to handling for me.
Adding more castor via the Cusco (rosejoint/pillowball) traction arms made the next biggest difference.
Then refreshing the bushes in the rear subframe inc rear diff made a big difference again.
Yeah I run a set, unless you run lowish ride height you don't get enough negative camber for track work. I only just this week had them swapped for adjustable camber arms instead so will set the nismo stuf if you're interested.. (recently changed suspension and car sits higher than before).
