I have it, I'm really impressesd w/ the entire suspesion, it flexes extremely well, once the springs broke in and got the right offset wheels. Never rti'd it, dont really thinks it proves anything. But it worked really well at paragon and in trails in my area. The only things I didnt like was the $300 shipping and if you do decide to get this kit DO NOT USE the ifs steering box templet, ITS WAY OFF. Any specific q's, ask.
