I got the aluminum trailing arm kit for my R50 as well as a nice rear subframe from AllMag. It was all packaged well and arrived in good shape. I installed all of it on my r50 and the rear end of my car is like new for a good price! I did new wheel bearings, brakes (calipers, pads, rotors, hoses), and a new sway bar with the subframe and trailing arms. 5/5 stars would recommend.
