Hello,
We offer a variety of systems built on the stock spindles that do not require the tubular upper control arms. All systems on the stock spindle include spindles due to the fact the spindles needs to be modified to mount the brake. The system is simple to install due to the fact we will pre-assemble the brake system on the spindle, so when you get it, it is ready to hang on the vehicle.
Systems come complete with spindles, aluminum hubs, aluminum calipers, rotors, braided brake hoses and brake pads. These work with the factory master cylinder (powermaster or booster)
You can order this system through a number of TR venders some off the top of my head are Cottons Performance, Conley Performance and ANS.
Hope that helps!
