is the suspension on the sc as soft s that on the 2004 v8?

driving the ffrr and then the d3 v8 feels like chalk and cheese - a lot more body roll on the ffrr than on the d3, which feels a lot more planted

now wondering whether a change to a 2007 and later sc will drive better ito road holding especially when pushing on

My brother has the 4.4 V8 and i drive a 2006MY SC.... The SC feels very assured when pushed hard so i would not hesitate in going for the 2007 you mention..

I think the suspension was uprated on all 2007 cars.

Chassis & Suspension

The HSE’s suspension calibrations (spring and damper rates) were "upgraded" to match those on the Supercharged model, giving a somewhat harder more sporty ride, with vertical wheel travel reduced to 7.6 inches/194 mm at the front (down from 10.75 inches) and 11.5 inches/292 mm at the rear (down from 13 inches). On the other hand, the recalibrated suspension settings evidently gave an increased ramp breakover angle in off road mode of 30 degrees (instead of 28 degrees on the 2003-2005 models). Past (too many to list, but a few favs)...
