koni's are AMAZING struts... Just depends on if you are willing to do the research and source the parts needed to make the combo comfortable and stiff at the same time...

There are a few threads I have read but here is one with a quick search^^
Another thing I must say about my KTS is my friend got into an accident with my car a while back...hit a big ass curb doing about 20... popped the passenger side tire up onto the curb and smashed the shit outta the rim, control arm was completely twisted as was the tie rod, sway bar end link and tension rod were also slightly jacked up...
KTS coilover? still works perfectly fine besides some
slight bendadge at the very top where that bolt screws on...
My SPL outter tie rod ends were also still in good shape... +1 for SPL
