PRE-ORDER FOR THE GT86/ GR86 DMBD Kit ...

These will be shipping in about 4 weeks from October 7th 2025 depending on manufacturing times.   Limited quantity of 10 kits to start.   

The ALARIA “DMBD” (Dual Master Booster Delete) for ABS Specific Tilton 79 series Master Cylinders.  

This setup eliminates the OEM booster and master cylinder and replaces them with two independent Master Cylinders (Tilton) and allows true bias adjustment via the balance bar and optional remote bias knob in the cabin just like a pedal box.   

We understand a lot of people want the “industry standard” 6:1 ratio, but having the ability to make the pedal softer or harder, will make any driver happy.  Depending on application, ratios will be configurable in a decent range similar to that of aftermarket pedal assemblies. We thought this feature was worth the wait and we hope you do too!

Master Cylinder and Balance Bar are NOT INCLUDED and will need to be purchased separately
