I love the design by dukedoks and just wanted some more ground clearance. So I made the original rims wider and designed bigger tires from scratch. The tires give about 15mm more clearance and really improves the traction.
I still use a normal SG90 servo and the car is very responsive. The tires were printed with CCTree TPU with a 6% gyroid infill at 40mm and took 5 hours per tire.
Another change is to use m3x45 bolts for the front wheels and to put an m3 nut at the end of it, I found that on the original car the bolts would eventually loosen causing the wheel to come off.
