I just installed the AC Racing Propeg nerfs and heelguards on my Predator. They are awesome. Not the easiest things to install but they are really no harder to install than anything else on the market. If you get some, and you want to know how and in what order to install and put them together send me and email. I can probably save you some time and frustration since i have already been through it. I put some pictures of the installed nerfs in my profile. Check them out.
