I have had the H&R coil overs fitted to my car along with my H&R ARB's.
The coilovers although provide a harder ride & the car seems to jiggle more on bumpy roads - it seems to soak up bumps MUCH better. I would never describe it as a harsh ride - it really soaks up bumps etc great. Cats eyes for example are not as harsh when driven over & the car seems to sit much firmer on the road. With the standard suspension I seemed to fight the suspension with bump steer/tramming on un-even surfaces.
Now... onto the ARB's - the car is like nothing I expected. Cornering is just a delight. The car corners dead flat & simply sticks like glue. The tail feels planted and the car turns in great (Similar to what it did before) but past about 2 o'clock where I used to experiene understeer - now the car just keeps turning in harder & harder the harder I turn the wheel. It is amazing. Tight roundabouts the car just soaks up and spits out.
The whole setup is simply amazing!! I am truely amazed at how it handles!
