Chase Bays Dual Piston Brake Booster Delete with Bolt-On 6:1 Pedal Ratio | 1999 - 2006 BMW 3-Series E46 & 2003 - 2008 Z4 (CB-DBBE-E46)

Dual Piston Brake Booster Delete with Bolt-On 6:1 Pedal Ratio by Chase Bays A properly set up Manual Brake Conversion Kit improves lap times and makes for a more controllable drift / rally car. There is a lot of incorrect information out there about Manual Brakes, from forums to other videos. Chase Bays has sold over 15,000 Manual Brake setups in the last 10 years…everything from winning Road Race chassis to winning Drift chassis. A proper manual brake setup (matched ratio with MC bore size, good pad compound, and Front / Rear Bias Adjustment) is the exact same braking every time. The modulation of max braking just before lockup is where manual brakes really thrive. We call it the 90-99% zone. Finding the exact level of leg pressure to get that exact threshold is just not possible with power brakes, they’re too inconsistent...especially with boost. Acquired Motorsport Data isn’t wrong. YES the 90-99% zone is a little more leg effort than power brakes but that’s what makes it so great
