@spikeyxxx Absolutely we should use your wheels. I just saved a SPIKEYXXX_dog-434e_wheels_MASTER.blend. However it appears that they don’t align with the rear hubs. Spikey, if you could duplicate the front wheels to the back and @duerer if you could adjust your axle to align with Spikey’s wheels, I’ll link them into the master assembly and check that off the list!
