A stiffer anti roll bar will always result in better ride quality provided the springs are not over damped
The regular Figo with 15 " wheels is a good idea, but I feel Fords Figo has already got a lot more softer than what it should be in regular form, the Figo S is how I feel a regular Figo should have been and the S should have been even more stiff,
See I drive a Figo MK I 2010 model car, a petrol one, and it any day is stiffer than the current gen Figo, but in reality after driving the new Figo and my car back to back I feel my old Figo rides, better, sure at lower speeds it will push and tuck the passengers inside a little bit more but the moment the car gains speed over 40 kmph the advantage of stiffer springs are obvious, the car will remain way more flat and has a TAUT feel, the regular Figo will float and see saw a wee bit, but the S will stay SOLID, which is far better feeling and in my view adds more comfort
The regular Figo with 15" does give better NVH, but wont be able to mask the underlying softness of the springs, this means the cars damping still wont improve ,
The S has 10 mm lowered springs but since the wheels are 15 " the Ground clearance remains same and reduced spring rate means faster rebound compared to slower rebound in regular Figo which is not a good thing to have for a car with an agile chassis, the Figo S actually too is not that perfect, but still its closer to what a real Ford is than the regular Figo.
