Mercedes FRIC

Anybody got ideas on FRIC it looks a lot like Hydra Gas but working in the verse sense ie it reduces dive and squat rather increases, istr Len Terry was suggesting connecting front to rear suspension by anti-squat torsion bars back in the late 1960s. Not sure how the function in roll differs from an ARB.

Ermm... BMC's HydroSpastic resurrected ? Hopefully better thought out This time :-)
Although German Engineering ain't what it was.. at it's high water mark.. ...back in '44

From my current understanding with the data available....

as the car enters the braking zone and weight starts to be transferred forward the rear suspension try's to "extend" which operates a valve sending hydraulic fluid from the rear dampers to the front dampers causing the rears to squat and fronts to extend. This is probably only between the front and rear bump dampers and not the individual wheel dampers.

The aim is to ensure the aero platform of the car remains constant and stable at turn in as excessive dive causes the front wing to work better (as ground effect increases) and the rear diffuser throat section to work worse so balance shifts forward creating nervous high speed oversteer which remains until the car settles back to its neutral ride heights.......

As for effect in roll, I would imagine the initial transition at turn in to be sharper but as it only affects the bump damper (both wheels going up and down together) the car will work as designed as it turns due to the individual wheel dampers not being affected......

Well.... That's my understanding of it.......
