These are not race seats , ford never claimed them to be race seats and the focus rs is not a race car , it's a production car with seats styled like race seat that have met all the regs for the purpose they where designed for , driving down the road .
Any moron that fits these into a track car or any seat with an adjustable back wants there head looking at , and then to fit a harness wrong and expect the seat not to collapse is shouldn't be allowed nowhere near a race track.
That focus above has had a massive wallop and personally think that the seat has held up pretty well seeing as everything was fitted wrong
And sparco make many a seat for race applications that are used in most Motorsport teams around the world so calling them shit is just silly.
Your warning should say this is what happens when you don't use a proper Motorsport spec seat for a Motorsport event wether it be track day or full professional use
