Adding new rims would be cool, especially adding Speed Star Rims, they are veery nice and cool and good and yes.
3 spoke, 4 spoke and this little 6 spoke rims.
I made them rims to add this next update, but they are all generic designs for NFSSA "brand".
I don't think they are willing to add any new brands for now, but as always, I can only speculate.
