LC300 and LX600 builds rarely stay light-duty. By the time you add a GVM upgrade, long-range tank, steel armor, drawers, fridge, roof tent and family on board – plus a van or boat behind – you’re asking a lot more from the front brakes than Toyota or Lexus planned at curb weight.
The TTSPORT OR6 front kit is built around that real-world use. A forged 6-piston caliper with 79 cm² (12.25 in²) of piston area clamps a 34 mm thick high-carbon rotor, giving LC300 and LX600 owners the braking torque and heat capacity they need for long, steep descents and hot highway stops with a full touring or towing load.
If your Land Cruiser 300 or Lexus LX600 is built to travel, tow and cross countries instead of just suburbs, OR6 is the front brake upgrade that gives you the margin you expect from a modern heavy-duty system.
The LC300 & LX600 OR6 kit uses our most demanding off-road hardware in a platform-specific configuration. The spec below is what turns a fully built 300/LX from “it stops eventually” into “the pedal still feels good halfway down the pass.”

Look, we know you get it. Your brake kit is custom-made for your specific car. That means once it's built, it's yours. We can only accept returns if there’s a genuine quality defect from our side.
Sometimes, aftermarket wheels can be tricky. Depending on the design, you might need spacers for clearance. We’ll do our best to help you figure it out, but issues related to wheel spacers don't qualify for a return.
To get this right the first time, we need your help. Before you order, please give us the following info:
We’ll likely ask you to confirm some measurements and send a few photos of your wheels. Please double-check everything you send us. TTSPORT isn't responsible for fitment issues if the specs you provided were off.
