Do I really need a T-Lok...

...for a daily driver going to 3.73 gears?

If you need 3:73 gears then you need a T-lock. If you don't think you need a T-lock then you probably don't need 3:73 gears. It's a backwards way of thinking of it but thats how I see it. And if your going to get gears installed then you might as well get a T-lock since everything is opened up. It makes a big difference when both wheels can grab asphault.
