Leda does have a kit, but Racer's Edge wasn't aware of it.. I wasn't looking into that too much though, you'd have to ask them. I was after custom stuff.
Racer's Edge spec'd a couple suspensions for SVTs though. I'm sure you could ask them to duplicate that.
BTW, mine is NOT for the faint of heart, if you ask them to copy that, make sure to speak with me and understand what you're getting into..
