more accurate ride height. I'm tired of trying to lower a kit to a more proper stance and end up making a clown car.
No more separate bumpers, It can make a real mess. But with that said I'd make all the cars with seperate grille inserts.
I would TRY and expand a parts pack line for wheels, tires n stuff like that. I know R&D, tooling and manpower cost money. But we all here spend a good amount in resin, release agents, aftermarket, shipping etc. So its not like there isn't a market for it. Especially if you can get stuff that is designed for your kit already.
