Nice, not a bad deal...as most prices I've seen on them are closer to $250. Where'd you get it, if you don't mind me asking?I just order and received yesterday the Optima yellow top for $200 delivered. I too have a few extra lights and plan to upgrade the sound system and after almost 3 years on the stock battery, I've noticed the startups taking longer and don't want to get stranded so I upgraded. My research on batteries led me to the same choice but sorry, I can't comment on the alternator.
My T is a '10, and from what I can tell it still has the stock battery. Though I could be wrong. It definitely doesn't look like anything special though. It seems to start well enough, but I figure I may as well just go ahead and future proof myself if I'm going to be making electrical mods anyway.
