The RAD Industries Billet upper control arms for MK4 Supra were designed to be the best upper control arm on the market period. Not only do they look amazing but they also have the features needed to function the best as well. We made them out of Billet Aluminum to be super strong but also lightweight. They feature a double adjustable union on the knuckle side with a rod end and tapered through bolt. This allows you to adjust camber without removing any hardware and then locking down the jam nuts and getting right back out on the track. We also designed these arms with spherical bearings on the subframe side. These arms are on our Formula Drift race car and Cody Phillips Drag Supra with 2800HP. They look the part and also perform under the pressure of racing and will work great on street Supras as well. These arms will also fit on SC300/SC400 and Soarers. We have also included 3 drilled and tapped m6x1.0 holes for ease of mounting the brake line and wheel speed sensor wiring to. These arms are must have for a serious Supra.
