Raptor Sprint Car
Here is a sneek peek of the new rear end configuration for the Raptor (Kyosho based) Sprint Car.
The transmission has all steel gears and a fluid filled gear differential
The diff can be flipped over in the case if motor and speedo allow for reversed rotation to change the torque on the chassis
Other changes will include:
Adjustable caster blocks so that caster can be adjusted while they are still mounted on the car.
Adjustable front and rear track width
Adjustable rear toe in a couple seconds without removing any parts from the car.
Adjustable "reactive" rear toe in

First run at the WCIS Round 3 race.
Finished car and showed up in time to get 5 min of practice with new car before qualifying.
Needed more tuning time than that!!!
Qualified in the C main, but kept getting closer on the set up.
Bumped into the B
Bumped into the A
Finshed middle of the A
Still need to work on tuning alot

Quick Adjustable Rear Toe with use of turnbuckle wrench
Reactive Toe in adjustments made with ball stud height adjustment
Ball stud height can be adjusted to add "Reactive Toe In" in the same way that "Bump Steer" can be adjusted on the front end of most cars.
The rear toe in on each side can increase or decrease when the suspension is compressed.
A small adjustment will only allow slight toe changes while larger adjustments will allow large toe changes during suspension movement.
