This is an upgraded booster/master GM unit for a TR8 or TR7. It is a larger diameter bore for superior stopping capability. We use this in our 4 wheel disc conversion kits.
With a new booster and master you will notice a difference in the pedal feel right away. We run this setup on all our personal cars
No core required. Comes with lines and adapters to fit to your original lines.
