There may be a thread on this but I went back a ways and didnt see much- Thinking bout goin with a twisted pg setup and probably kmod with the raptor shocks looks like the ticket, the powder claw wont hook up now just spins, the lugs are all bent over and its only got 1500 miles on it. So I would think it would be much worse with that much more power- just seeing what you guys are running with a 153". I dont know if there are many other options besides challenger/ C extreme. I have also heard people say these dont last long and the customer service sucks. appreciate the input. Sled is a '11 m8- thanks
