Its not really double when you factor in savvy's comes with a motor mount lift, body lift and tranny mount included.
Still a bit more money but nearly double when comparing apples to apples.
The major difference being you can do a dropped version of undercovers that doesnt need a tranny mount or body lift. If you want a high clearence one from UCF, it required a mml, bl, and lo pro tranny mount and comes out to the exact same price as a savvy. But the savvy is a slightly better design, and does use higher quality material.
So if slamming the drivetrain is the goal, the savvy is the better dollar spent.
If doing it on a budget and belly clearence is less of a concern, the UCF will definately serve the purpose.
Just wanted to clarify that. If you want the same thing savvy offers from UFC it cost the same money, making savvy more then competitive regarding what they are offering.
