My friends IS300 had coilovers install by RANZ. It was downright atrocious, nothing was adjusted and it was not tightened. When we took it to TWS, Albert had to completely re-install the coilovers. He thought my buddy try to install it himself. He couldn't believe a shop had install it.
I have never gone there, nor will I ever will. After I saw the facebook messages it just solidified the fact that these guys are clowns.
