So Unabomber (Ron) got himself the Klunk Killer Race version, and then slapped on some Kartboy rear subframe lock bolts. He liked it so much that he kinda went nuts. Well, he’s already nuts, but what I mean to say is that he got really really excited about how tight and responsive the backend of his car felt. So, given Ron’s excitement we decided to add the lock bolts to the Klunk Killer (Race) package, and save folks a few bucks. Since Ron was SO excited about this setup we decided to just go with the name he suggested. Thus you get Unabomber’s Sexy Rearend!! Please note – there will be an increase in NVH with this mod
