Make sure they are 7 wraps. You can also use the stock rear shock off the same LC. Could get them cheap, this way you can see if you like them after install. Then you can upgrade the shock later if you want. If you dont like it you can always sell the setup on here to get all your money back. But believe me the 7 wraps are awesome with tokicos. They flex like crazy, about 3.5" lift and ride really good with stock LC tokico rear shock which are stiff and they tighten up the soft 7 wrap. Toytec released the superflex to try and get sales from guys doing the LC coil swaps.
This is exactly what I'm planning at this point. Just need to decide on what to put up front. Really prefer the adjustability of the threaded coil over.
