I've been working on my sohc turbo civic for a while now, and I've got LSD on the way to help with traction, and also some BFG's.

A few people have been telling me to get a 2 step also, and that I'll really need it.

I'm not too familiar with this, so could some one explain to me exactly what 2 step is.

I've done research but couldn't seem to find anything.

Thanks for the Help,
