A Look Inside Dai Yoshihara’s Pro Drift Machine


A big but lightweight Wilwood 6 piston caliper grabs a full floating super light dirt track unvented solid rotor mounted on an alloy hat.  Drifting requires brakes with a lot of bite and modulation but does not require repeated stops from high speeds so long term fade resistance is not an issue.  The braking system in the Lexus has been designed by Scott to be light and highly adjustable.
The rear brakes use twin Wilwood 4 piston calipers with a lightweight floating dirt track rotor on an alloy hat.  One caliper is attached to the footbrake and the other is a turning brake, activated by a driver operated handle just like a rally car.
CNC Industries supplied the pedal assembly that is mounted on this pedal box.  The pedal box provides more protection for the driver and a strong, rigid mount for the pedals.  The brakes use  dual Tilton master cylinders with a balance bar which allows full linear control of the brake bias.  Adjustability of the bias is very important for drift setup and its tweaked from venue to venue.
The turning brake has its own independent hydraulic circuit.  You can see the master cylinder attached to the turning brake handle bracket.
The reservoirs for the brake and clutch system are mounted vertically up high on the other side of the firewall for easy and complete bleeding.
Dai’s office is cleanly laid out with the ergonomics perfectly adjusted to suit his size and driving style.  The wiring and plumbing layout is exceptionally clean and the signature of sano racecar construction.  Note the Motec dash awesomeness!  The rear mounted pedal box and extended steering column allows Dai’s seat to be moved over a foot rearward–about even with the B pillar.  This improves weight distribution and provides better protection for Dai in case of a severe frontal impact.
