FINAL DRIVE CALCULATOR
Tune the final drive for your WRAP-UP NEXT Chassis. Explore FDRs with different Motor Pinion and Spur Gear combinations. Select FR-D V6SP or Travis 2. (Max spur gear will be adjusted)


SHOCK PISTON HOLE AREA COMPARISON
You can easily calculate the area (damping) ratio of piston B to be compared to shock piston A, which is the reference piston.


SUSPENSION STROKE SIMULATION
This simulator can visualise the amount of damper stroke and suspension arm stroke when a 1G load is applied.
Data for front and rear weight, spring rate, lever ratio, spring free length, and spring set length is required.


SPRING RATE SIMULATOR
Even without a special measuring device, you can find the spring rate by simply entering the wire diameter and number of coils of the spring.
