On the first or second picture in the article the steering is turned in. The wheel is slightly inclined. This looks like "modern" Ackermann steering. With the old Trad the wheel would stand straight on the vertical axis.
I'd expect it has front suspension evolved from the Aero S5, so upper and lower wishbones, coil over springs/shocks and an ARB.
The back is probably the same, or it could be as in the original Aero. Morgan has a patent on that.
In that photo the difference in front/rear tyre width seems big: the S4 Aero has 245 rear, 225 front. The fronts look narrower than 225...I'm assuming 18"wheels.
