I've done a search, but there seem to be a lot of conflicting "opinions" on this.

I had always been under the impression that Koni Yellows do fine with the Sportlines (or any springs with a similar drop), but I'm reading now that the Knois don't handle a drop lower than 1.5 very well.

So the question is, what are the other options?

 

The yellow's pretty much handle almost anything you throw at it. The spring rate makes the difference but I have my yellows with coilovers and pretty much dumped and they are great.

 

yellows will easily handle sportlines. you might even be able to squeeze by on the str.t if you don't plan on ever increasing the rate past sportlines. the yellows are the better shock & if you can afford it, do so
