Glad you like the direction we are going here. Indeed we are going to be less than half the cost of XIDAS so we don't see that setup as competition with this setup. WE see our new setup here as ultimate budget coilovers, hope to have the retail for what you see here at about $1199.
We will be selling the threaded body KONI as a stand alone item and customers can then use our SWIFT springs in whatever rates they want, and we will offer the bits to make it all fit together. But having driven it with half a dozen Swift spring combos my highest joy level is with the Progress custom springs we ended up putting in here. For pure race cars the linear Swift springs are the way to go for most predictive control at the limit on the track, but that serious track customer is likely going to spend at least two or three times as much for another coilover solution anyway. I drove this setup home from the shop yesterday and it is smooth down the freeway over expansion joints in the concrete in a way that nothing else is beyond the standard KONI with standard Progress Springs, yet this setup sticks in high speed corners with mega confidence and is much more predictive at the limit than something as soft as our standard lowering springs from Progress or TEIN or Racing Beat, etc.
As for XIDAS on travel, good product but they sell more travel than NC can actually use at rear for typical upgraded wheels/tires and then sell the customer travel limiters to give back all the extra travel. Already had customer here with 'problem' they couldn't figure out and I got my head under the car and showed them that the rubber tires were acting as a unique rubber BRAKE, the tires are bottoming against the metal in the NC rear fenders. The cure is to limit the travel with the travel limiters that cost extra from the same place they bought the XIDAS. PT BARUM would have been proud of that effort, tell people they need more travel than they can use, then sell the cure to the problem created by the same product. Rear XIDAS travel starts at 171mm of stroke, but if you add their 38mm stack travel limiters you end up 133mm of stroke. Here with the KONI we are 136mm rear stroke or pretty much the same without the round trip and extra costs of the packers.

I have two sets of tires for this car, 235/40 on 17x8 and taller 225/50/16 on 16x8. Both those combos hit the car if I lower it under 13 inches all around. Thus, we could give a ton more travel but I don't see it being actually useful for typical customer, most NC owners working with performance suspension are using bigger than stock tire/wheel sizes. And letting those upgraded wheel/tire combos brake against the metal of the car is not a good answer in my opinion. For our OHLINS coilovers we always have to add packers for Laguna Seca or the car can't make it down the corkscrew, having even more travel would just make that situation worse. Picture of the 16x8 combo, can't go lower and can't do any more travel and actually have it work.

Yes, I will put the shock dynos up. Already have them somewhere but will get them posted. Product already got green light, all bits are in production and hope to have it on the site as the ultimate budget coilover NC setup in about a month.
Picture of the 17x8 and 235/40 combo. Heights 13.25 front and 13.5 rear. Everything clears with current heights and current travel.
