I'd agree with most of what's said about Carrera cars. Would add that they seem to have licences for some makes that Scalextric struggle with (ie Ferrari)

On the subject of there performance, and acceleration out of a corner. Is it a case that the gearing is too high on them? I know their weight doesn't help. but would there be any way of lowering the gearing a bit, or is that hard to change?
