Wheel covers for Transformers Legacy Dragstrip, modeled after the wheels on the Tyrrell P34 race car that Dragstrip is based on.
To install, simply press the small tab on the back of each wheel cover into the clips on Dragstrip's wheels. Parts come on a sprue and must be cut off before use (see render). Photos show FDM prints from a Prusa MK3S.
