Suspension motion ratio and corner weights T350

[SimonRogers]

Did anyone ever find these motion ratio's as I am in the same position with a customer as Simon at Cornering Force.

The front and rear rates would be interesting,but I don't think anybody knows.
I can tell you the 41 mm Nitron dampers and 400lbs front springs produce a pretty firm front,but you still get IMO too much dive under heavy breaking.
This is often paired with 350 lbs rear springs,which I found too soft by some margin.
Same dampers,fitted with 500lbs front and 450 rear is at the extreme end of the road envelope ,but I am content with this.
Does your car bottom out at the rear,or foul the wheel arches at the rear? Does your car rear hit the ground? ( all with slightly increased ride height Mine did with 350 rears). If this isn't an issue you could go 350 front and 325 rear maybe?

The rear dampers are very significantly inclined relative to the fronts, therefore some people, and the works fitted stiffer springs on the rear of some later cars eg Tuscan MK2!
