What are yalls thots on this. I have a friend that has springs tweaked all the time and hasnt had any problems so far. He has had several inches done and I was wondering about getting 2 more inches in my 6" springs. He has an account w/ the company that does it and he can get them done for 35 bucks. He is having a set of 12 in done now by them. I think those are all new and not a rearch. But he has had them tweak 12 " to 14" w/ no problems. If ya can't stop.......Smile as you go under!
