Tips and Tricks for the Tamiya TT-01. In this video, we increase the ground clearance by using more spring travel and turn the TT-01 into a Rally-Car. If you have any questions, feel free to contact me!
Sorry i can't tell you, I don't own a TT-02. But you can try to remove the base plate and the shocks. Then you see if the suspension can even travel any further.
For TT-02 I believe just using the longer bottom ends of the cva shocks will help you get more ground clearance and you wouldn't need to cut the front and rear skid plates to make room for the lower arms to travel further down.
