FWIW.... I do not race with this car but I have seen a weak point on the chassis for a few people with this chassis.
The furthest screw holes on the rear of the chassis for the toe blocks appear to break on heavy impact.
Apart from this, they appear to be a durable, simple car that would be a good starting point for someone getting into TC.
That said, I would take a Sakura Zero S any day over one of these. They look to be the better car at my local club on carpet and are more durable as a whole.
