The Viper/RX-1 skid is a good upgrade simply because of the affordability and ease of installation, they bolt right in. The viper skid WILL absorb the bumps better, just don't expect a huge improvement, but it is better. I'll bolt a viper skid in an SRX anytime, simply because it's an upgrade, and you can sell your SRX skid and recoup almost all the cost, it's a no-brainer for me. Now if you're looking for a Cadillac ride that eliminates the bumps all together you'll be looking elsewhere. I have an Expert-X and I love it, although once you get into raising the back that much you really need to do some major mods to the front end to match the ride height. Once all these mods are done you really don't have an SRX anymore, all the character is gone, if that makes any sense to you. My advice is go with the viper rear and set your shocks/calibrations up to what you need and call it a day. If you want to go with a better skid in the future you can always sell the Viper skid for what you bought it for.
