Pretty sure the RC Car code can be changed for not to explode, and a more suitable add-on can be made.
Make it look like a muscle car (any one, idc)and an ice cream truckEdit: also guys you're pretty late on this whole sapper racing idea...it first came in like 3-4 months ago, had a lot of servers and detailed huge racetracks, then all of a sudden the servers stopped hosting it.
I don't see why you don't just make your own track pieces. I used to host RC raceways, and you can build a good track (excluding scenery) in a couple hours or less without downloading someone else's track parts. And for those of you wondering, yes, it's very easy to mod the RCs to not explode on contact, as well as changing its colors.
