Is there any way to allow both cars and motorcycles into a single race on GTA:V?

Else, how do you do the Z-type + bike bumps, because of bails and shit? cheetz?

Deathmatch let's you set team spawn points and lets you place vehicles of any kind (5 different ones) and you can place 32 of them. So slam down like 25 bikes and 12 cars and you'd be good. It's probably good for it, but as far as I know you can't have custom vehicles. So freeroam is probably the best way to do it, tedious, but best.
