After much research and help from you all, he decided that spending over $6500 on his S4 was not the direction he wanted to go. He does have a set of K04's and bolt kit that was bought brand new from Achtuning and it was never installed. So anyone interested on getting your hands on some new and never installed K04's send me a PM. If your in the Wa.st. area (Tacoma) that would be better and this is first come first serve.
