I was looking for a good set of quality coilovers and came across ISC, i have had them on my car for 5k miles and they have been great. They are 32 way dampening adjustable and height adjustable, reliable and only cost around $900 bnib. I would definitely recommend for anyone looking coilovers on their daily/track car. I have pushed them hard on the street and they have performed well. Customer service is top notch and quality/performance is much better than my previous Apex-i N1's. Great buy.
They are made in the US (New Hampshire), and ISC offers custom springs from the factory. I have 12k/8k. They ride great, soft setting rides very close to OE ride quality, and firm setting handles great.

Are rebound and compression valved separately like a Koni, or together like a AGX?
i am not sure to be honest, they are a complete one piece coilover though.
The biggest complaint I've read about the KYB AGX shock is that the adjuster alters both compression and rebound, which means as it gets stiffer it handles bumps more skittishly, its more prone to lose traction over a bump. Where a Koni is just going to be firm, not unsafe.
At least, that's what I remember reading. The take away is that having compression and rebound separate are important and the reason why cheap shocks are cheap. IIRC this is also the issue the new Tein Street Advance coilovers have.
[EDIT] I checked their site. Compression/rebound adjusted together.

From what i have noticed, when they are set on hard, the coilovers respond quickly to bumps and the car handles great. When i have them on soft, the car takes bumps really slowly. I don't know how to explain it, the car rides smooth on soft and takes up smaller bumps better, but larger bumps are very loopy and annoying. I have found the best setting is right in the middle for daily driving and all the way on hard for harder driving.i absolutely love them.
Plot twist: dc2_brewer is a sales rep in disguise, promoting the isc coilovers. I do like how the height is adjustable without affecting shock travel on these though. isn't 12k/8k super understeery. The 8k seems really soft for the rear on a dc2.
sorry man, im not a sales rep haha. During really hard driving the understeer is evident, i would definitely get stiffer springs if i was tracking the car. But i like the stiffness for mostly daily driving
They're around a half hour from me, and they did a fair amount of work on my Miata. We got my dampers on a shock dyno, workout out exactly what springs I'd need, and I got to have a look at their BRZ while I was up there.
On a street car or light duty race car, combined compression and rebound is nice. I find that I don't have to fight with my settings as much, and can get a solid 'coarse tune' that works in nearly all situations on whatever springs I'm using. If I'm tuning suspension for very specific conditions (like a specific race track and consistent conditions), there's definitely value in isolating preload, damping, and rebound. For everything I do though (hillclimb, rally, and daily driving) I'd much rather have a good all-around tune.
Unless you can find some a really good deal on Bilsteins or Koni Yellows that are already valved for your spring/chassis combination, I can't think of anyone else who can even compare to them for the price point. If you aren't really concerned about price, Ohlins all the way!
They also have coilover sleeves, which I haven't seen anywhere else. They have them on all the Subarus at the shop, and seem to do their job really well in winter. No road grime or salt slush gets in, and the coilovers come out looking like new in the spring.
... just my $0.02. Definitely do your own research, but I'd give them two thumbs up without hesitation.
Assembled, not machined. They aren't trying to mislead anyone. ISC-NA is the North American distributor of ISC. Some people get bent out of shape about where they're made, but if I'm getting a good price and solid support (which is often tough to find, regardless of Country) I can overlook most downsides.

I know, just joking. They look like good. Yeah thats what i thought. fair enough, not everyone wants to daily race car style.
