Anze enginerring Penske 8100 (sold as rebound adjustable, canisters can be added to make them double adjustable).
AST 4100 setup worries because their published oem spring rate data is wrong. Hopefully that didn't mess things up when R&D was finished.
Not a coilover setup but Koni 8212LB shocks with Nissan Motorsport T2 springs would be another good choice.

Not sure if this will help, but: I bought BC BR series (OEM-type) coilovers and installed them this past summer. I decided that since it was my first ever set of aftermarket coilovers for any car I've ever owned, i.e. I had no real basis for comparison, that I would go the "budget" route and BC BR series fit the bill. Following are my thoughts:
Pros:
* Workmanship of the product appeared to be good out of the box
* $1100 price point
* Easy installation due to the front springs coming already installed on the struts (some aftermarket systems require re-use of the stock front upper strut perch, which requires compressing and removing the springs from the struts)
* Easy height adjustment
* No unusual clunking or other odd sounds following installation
* Decent range of height adjustment
Cons:
* 30-way settings just means it's easier to lose count when you're trying to get to the same number of clicks side-to-side. And there is very miniscule difference from click to click. They should have gone with 5 or 6 total clicks like some of the higher-end coilover systems
* I feel that the springs might be a bit too soft for the dampers, in that when I have the dampers set toward the soft end I feel like the car is going to crash down through the earth every time I hit a small dip in the road. On the other hand, when I set the dampers toward the stiff side they don't seem to rebound fast enough when I hit bumps so the car feels like it briefly loses contact with the road after hitting said bump.
Bottom line, IMO these are not a performance-oriented coilover. I think handling was just as good, if not better, with my OEM struts and Hotchkis springs. I don't track my car at all, but I doubt these would help me get around the circuit any more quickly. If you want a cost-effective way to make your car look better vis a vis lowering it, BC BR series is a good solution.

Those are great but have killed all desire to drive my car on the street. The spring with more preload makes way too much noise. I'm thinking about machining a bunch of eccentric lock-out squares with offset holes for a simpler solution to toe.

This takes car of the problem , if it wasn't backordered for 3 months at the time i was buying my setup , i would have them.

Those nuts on the upper damper mounts are tiny, I didn't want the spring there unless its reinforced.
Also,
"Separation of the springs from the shock absorbers resulted in 60 percent less friction in the residual moment, which means the suspension could react faster to road inputs"
They also say it gave more luggage space but that has to be complete BS with strut bar there.

There are so many people in this thread that just say "Go with this coilover, or go with that...bla bla bal" without any experience or knowledge at all...
I've only had a chance to ride in a car with BC and they were okay, the car was slammed and it was kind of bouncy, but I own stance, and track my car quite often and I am very impressed. Here is a review that I did on stance coilovers with some pics:

Hope that helped some, based of my experience. Feel free to PM me any questions.

I've ran BC coilovers on the dyno, and have seen dyno plots of Stance stuff from a trusted source... BC performs much better. I'd check out Fortune Auto personally.
Ride comfort is so subjective and very dependent on installation that it's just about impossible to judge coilovers based on that alone. Until you've verified the installation and spring rates and have driven both cars to the limit in similar conditions you can't really make a solid judgement. Shock dynos don't lie, though.

My only complaint is that they dont go a BIT lower. I would love to be able to tuck rim in the front.

Honestly - as much as I like the guy and don't want him harassed and should probably just leave his name out of it, Jason Z-ya was a wealth of information and his Suspension 101 thread is a must read from front to back before investing a cent.
I hope I didn't just fill his inbox lol.

I disagree strongly. I am at 12k/10k springs (probaby part of your problem not doing research on the springrate for your driving style) with 12 clicks in back and 20 in front. The clicks were pronounced and not hard to count (i went from 32 to 20 and from 1 to 12) Overall I am STUNNED at the transformation of my car... I am taking turns significantly faster and there is no noticeable body roll in the car anymore.
