Blue Optima Batteries

Doesn't Optima make blue topped batteries for the GT? I could've sworn they did but I'm searching online and everywhere I look only has red ones!?! :( Any other brand out there make a blue top???

If I remember right the blue tops are considered marine style batteries but some have used them in auto apps. The blue tops are also the most expensive of the Optimas. From what I gather they are a good mix of the yellow top and the red top. You would just have to find one that is the right height, and dimensions with top mount posts to use.

So no other batteries have blue tops? :(
