I got a Z-car and have been enjoying it but found it difficult to dial in the steering just right "even afer I made an
"Adjustable Suspension Bar" so I was considering doing a front wheel mod but dreaded the prospect of dissasembly/making the wheels and not knowing whether I'd like the results. I picked up the ZZ Fast & Furious kit for the motors and realized that I could take the thinner rubber tires and simply stretch them over the Z-cars front tires thus expanding the width. You just gotta work it on and make it even all around. I must say the bigger tires really help the car keep a steady track. Of course when i turn they catch on the chasis and i spin out so I would need to do some melting If I decide to make it permanent and I suspect the bigger wheels would benefit from the rare earth magnet but its a good way to experience full size wheels without the commitment.
