I have ended up with a set of Koni FSD that I bought for my Boxster, then they were on backorder and I ended up with a set of KSport coilovers, and then the Koni's shipped and were delivered before I could cancel. I got them from overseas (Carnewal) and so they are not returnable (well I didn't even check because the shipping would kill me)
Some details on these:

KONI NA | KONI NA | Best of Both Worlds
These will work with Factory OEM springs, or Eibach Pro Kit lowering springs.
LOWER PRICE: $700 + PP fees, free shipping on these
If you buy these and my other springs, I'll do free shipping on them too.
