Don't get hung up on the "inserts versus integral" design issue; it's irrelevant. The performance difference simply due to that design factor is insignificant. What's important is 'are the dampers doing what you need them to do and at a price you can afford'.
I ran Koni 8611s in the ITA NX2000, simply because there was nothing comparable available pre-made at a price I could pay. And, since no one made 8611 housing using a geometry that worked for our race car, Matt designed and fabricated our own housings. IMO, Koni 8611s are the best value-to-price strut damper out there; I never found anything that worked as well at that price. I did, however, have to have them revalved to work with the springs rates I preferred (~500F, ~1000 rear, at a near-1:1 motion ratio).
If you've got the coin, I don't think you can do any better than the Koni 2817 struts, but at $1500 each they're pricey. I suspect that had I kept the NX they'd have a set on them now...
So, again, scan the market for what's available for your car, and get some shock dyno charts to see if they'll do what you need them to. But don't get hung up on the design details.
