Cool beans. I bought 4s for the front thinking I had 4s for the rear but I have 5s on the rear so I sit a bit low in the front. Didn't have time to return them before Battlefest.Sweet! Did you find a gently used set?
You can add a D1XL leaf to the front pack if you add a winch (or if you just want to level it) and turn it into a CS005. The 005's are CS004 + D1XL.
