Main Improvements of V5 vs V4:
• New rear Gearbox with CVD and Gears.
• New rear independent suspension system.
• New 0610 motor.
• New H-sliding bar for rear Gearbox.
• Tuned front arm, servo horn and linkage lengths for less binding with linear servo.
• Shorter front chassis-A for new rear gearbox size.
• New Rear V5 wheels (only suitable for Gearbox system, which has a bigger hub bearing).

The 3 different height rear magnet “body mount” STL files are in the V3(sus) zip file. I forgot to include them in the V4 zip file.

DKR has carbon fiber plates, rolling rear spring suspension, bigger front hub bearings, lower top plate to fit more bodies, improved steering angles and suspension for better drifting.
DKS has all of DKR + rear independent suspension and gears box
DKM 3D printable.

All 3 have independent front spring suspension and adjustable slide length to fit different wheel base bodies.
