DIY is the way to go for a powerful RKP street board. Good RKP trucks/hangers are very limited so BN270’S are the way to go unless you can afford Luna 350’s from @moon (maybe someday) or a set of 275mm from 3dservisas. @Skyart might be able to help with those if your stateside.
This is what I ended up building at my attempt at a powerful RKP street deck. Asides from using pneumatics and super wide trucks, I wanted it to be as close to a normal longboard as possible looks wise
