Contact the Muffinworks guys and have them make you a custom set of rails for the Proactive Skid and tell them that you want them "beefy"!! I am one of those that just used the rail extensions on this skid and to be honest these OEM rails just aren't strong enough for extensions. After 500 miles on my set the rails where already bent and I know at least one other guy on here that has also bent his rails this year so far. Trust me if you only want to do this once than have rails made!!! Go to
www.muffinworksltd.com and check out there "custom work" page and you will see that they have made these exact rails before. The weak spot where I bent mine is right at the rubber bumper. Thats my 2 cents!! learn from my mistake!!
