Camber Plates/Adjusters

I just had a front end alignment done on my 96 Cobra. The camber has been adjusted as far as the limits will allow and is barely inside spec on one side, and just outside of spec on the other. Suspension is 100% stock and I plan on leaving it that way. I was thinking about getting a set of camber plates but need some advice. Is any brand better than the others? Are there any advantages in going with the 4-bolt setup over the 3-bolt plates?
Thanks!
 
4 bolt plates are best; I wouldn't consider a 3 bolt setup on a 94 & newer car. My only personal experience has been with Maximum Motorsports' plates, & they're very good.

What are the numbers you got on the alignment? Might not be bad enough to warrant the expense.
