I've got them in both my cars....

...however, I'm thinking the one in the WRX is overkill.

Pros:

Since it's a dry cell, it
- won't leak
- can be oriented in any direction
- resists vibration better
Also, it
- lasts longer
- puts out a higher voltage right until it dies, instead of getting weaker and weaker.

Cons:
- It's heavier than regular batteries
- It costs twice as much

I originally went to the Optima because I used to crank the stereo in the WRX while I was working on the car. I figured since I've got a battery charger, it wasn't too big a deal if I drained the battery every now and again while wrenching. Unfortunately, I did it so often that eventualy my battery wouldn't keep a charge. So I upgraded to the better Optima. They're excellent for cars with big power usage (like stereos and amps, etc) and for people like me that use the battery w/ the car off a lot. (In fact the deep-cycle Yellow Top is even better for that... lots of people use them for winches and the like.)

I'm thinking about getting a lightweight racing battery for the WRX, since I don't need the power like I used to, and a tiny battery up front would really help the weight on the car. If the EVO and the WRX use the same battery, I'd be willing to sell it to ya as soon as I can find a decent race battery.
