Currently, it isn’t possible to have event rims on Avanta R51B3T. There are only 8 rims available for Avanta R51B3T so why not be able to put event rims on it? With event rims put on such as the skull rims for example, it would raise the part count to above 230.
I think that players should be able to put event rims on Avanta R51B3T because it makes sense to be able to do so, given the fact it has 7 buyable rims and they are colorable.
