A thread about #F1 trick rear suspension.
Teams have been using a trick set up called "collapsible rear heave springs". This boosts top speed and has been a trick used knowingly by all teams for years.

At speed increases, downforce increases the load on the suspension, thereby compressing it. Compress too much and the airflow under the car stalls losing drag/downforce. There comes a point that the car has enough downforce even with a stalled underfloor, so teams exploit this.

As the rear compresses, the rear heave gas spring resists the force to keep the rear end propped up. At a predetermined speed, the load on the gas spring opens a valve, collapsing the rear to lower it and stall it.

Friday fun, a few weeks back I visited @MercedesBenzUK world at Brooklands. There's a load of F1, FE and historical Merc stuff there.
