Cool car, I like it. ;-)
Majority of Maisto cars and truck axles are made up of a plastic bushing that spins on a plastic spindle, the wheels slide or snap into those bushings. Using Dub City wheels specifically, drill into the part that the axle normally slides through(Very Carefully) to the diamater of the bushing. Slide to fit and make sure the wheels roll and turn, super glue(very little) in place and a custom bling bling ride on Dubs emerges. My previous occupation was a machinist and that helps alot when doing my customs. One is a Black UT Impala, I hated the wimpy tires and wheels it came with. It now rolls and turns on a set of Maisto ZR-1 wheels(same as the GS but silver finish). Another is a Ertl 1996 Camaro Z-28 Red convertible. The wheels and tires were terrible, was not to scale, and lacked detail & depth. Is now rolls on a set of rims and tires off a Welly 2002 Camaro SS. The weels are a lot wider and more to scale. Finally, for my Welly Camaro SSs(I have 3), I used a set of wheels and tires from Maisto Z06 Corvettes.
Just a few ideas to try :mrgreen:
BTW, Be carefull not to drill too far. You will likely end up with a hole on yourself, the work area, or a wasted wheel. It will take a little control. Mark the drill to the correct depth, use that as your guide.
