I have a full set of Sonic Tuning coilovers that are about as new as they can be. I had them on the car for about a month (under 1000 miles) and then removed them to put the car back to stock since I was selling the car / have now sold the car.
The coilovers feel almost identical to the stock sport suspension but the car has no roll and feels like it is on rails. Hard braking and WOT acceleration have almost no squat or dip and the steering is tight and responsive. It feels planted and predictable which was what I felt was missing with the OEM sport suspension.
These are the S1 version that you can see here:

They are currently going for $999 on Sonic Tuning's website and I will let them go for
$750 OBO.
