Hey I replied in thread but figure I'll ask here too. Can you explain a little more what you meant about the hks 4 feeling better than oem sport? Did you mean better from a performance standpoint or was it actually more comfortable over rougher roads? Did it do better or worse over rolling ripple bumps vs oem, better or worse over single square ended hits (freeway slabs). Any input you gain give would be great it's just super hard to get anyone to give a detailed review of suspension for cars for some reason. In the bike world it gets broken down into every aspect and scientific and then for cars it's just vague.
