If its for siting in macdonalds with Your mates why not. But if you actually drive your car hard I wouldn't touch them. Let's face it in a crash the starlets are going to be hard pushed to keep you alive let alone adding a set in no one knows how it reacts. If someone is pretty confident they will be fine in a crash I'll happily pay for one of the seats and a wee scrappy motor for it to be fitted to. If there prepared to crash the car at 80 while sitting in said seat.
