2-Step? Which one to get? Is it worth it?

Been thinking about adding a 2 step to my car, but I'm not sure if its really worth it. Working on a few other things to upgrade such as more suspension and half shafts. What are your guys thoughts?

Also here's a video of a friend's SC S197 launching off a 2 step.

I think its worth,they are not expensive and easy to install,they also make your car more consistent because u get better launches.Makes so u can go to the tree and dont have to worry about getting your rpms right,just put it to the floor and wait for the light.

I have the wot box and I love the 2 step, first it sounds pretty cool plus it really helps with your reaction times and really measuring where you sweet spot rpm is to launch at
