Impressions of RSR coilovers?
I searched, but couldnt find but one review(short to say the least). These look like very promising coilovers that are put together well. Anyone have thoughts on these? Im torn between Jic, HKS, Stance and RSR. Any suggestions would be appreciated.

As far as Jic, cross that option off your list. IMO, invest in the HKS III or Cusco Zero2. Why have you ruled out the Bilstein Pss9?
The following is a repost.
I've been here since mid 2003 and I've sponged up alot of information from posts dating all the way back to 2003, sometimes I recall posts done that for whatever reason cannot be found in the data base. Because of that, I would never buy Jic coilovers based on valving, reliablity, warranty coverage, and a lack of customer service.
Here's a post I did a few months ago that is on topic. Show's you Jic owner comments.
I didn't write any of the following.

how is the ride? Stiffness isn't a problem, but a harsh ride would probably bother me. The stock suspension's tendency to "bounce" is somewhat harsh. I'm hoping to improve the handling and fix the bounce simultaneously with a coilover install.

I just tracked it yesterday at thunderhill and knocked about 4 seconds off my time. Their use of mild spring rates really soaks up the bumps which ultimately allows you to go faster. The shock adjustments really make a difference too. You can feel the difference of just one click. I'll write a full review when I have the time.

I loved the zeals on my car. on the street it was 2 front and 3 rear and to this day i regret selling them because stock is worse than the zeals were

I'd think with the track oriented reputation they have, if they overheat then they're not very well engineered since their goal is all out performance.
The HKS's spring weights seem more neutral while the Zeal's is stiffer in front and looser in back. How would those compare?
I definetly want something track oriented/heavy duty, and well balanced. The HKS is less money, but I'm getting the impression they're more street oriented than track.

Not to mention the damping on them was horrible little to no difference between full stiff and full soft. It didn't really matter anyways because the damper adjustment froze on them anyway. I will never ever buy another JIC suspension product ever.

I have driven 2 Z's so far with Zero 2's on the track, but not my own car yet.

To add to my post above on the Jics,

(i have a G by the way, but the springs that i got are for the Z. however, you could change the springs, front and rear to another rate if you want).
i just got them, so i can't say whether or not they overheat, but if they have to be rebuilt every two years i wouldn't really "notice" as the car will see lots more track time and a lot less street time, so it'll be a good idea to get them rebuilt in that time span. i definitely didn't buy them to be comfortable, but their main office is about 40 minutes from me so if i needed something rebuilt, i would just go there to drop off/pick-up.
as far as your three "problems," which spring rates did you get? the 12k will drop quickly and be pretty jarring over a speedbump, but the 10k isn't that bad. maybe they installed the 12k's up front and the 10's in the back...
as far as your steering wheel shaking, did you have the car aligned? maybe there's a big difference in ride height (between right and left front)?
and lastly, the shaking that you feel on freeway breaks...unfortunately, that's "normal."

as far as "needs to be rebuilt every 2 years", I can't say for sure. Like anything else, it depends on the conditions they are subject to.
As far as your specific problems, some suggestions
1. find out exactly what spring rate you have up front. I think JIC stampes them with a white marking that will say the rate - don't quote me on this though. I'm assuming the car was fine over speed bumps, etc before the coilovers, so we can rule out tires/pressure. Spend some time playing with valving. Also, take note of the preload on the front springs. This will tell you if they were installed properly or not. You should have a minimal amount of preload on your front springs.
2. This could very well be the result of poor camber/toe. Again, I'm assuming the car didn't exhibit this before you installed the coilovers. Did you get the car aligned after you installed the coilovers? Post the results if you do. If not, get yourself some adjustable front a arms and an SPC rear kit, have them installed and get a real alignment done...this should resolve that issue at least
3. Not sure what you can do about this, as you are now the owner of one of the harshest coilovers out there. But, all is not lost. Assuming you got a good deal, you can buy lower weight springs and have JIC revalve them to suit.

It's the only set I've ever been on, as they just are not popular in our area of the country at all it seems, but I'd charge someone a big time price tag for dialing them in on a track day...they were that far out of whack (had me bobbling all over the place).
To the original poster - might help narrow the field if you post your budget as well, and your wheel/tire setup, as that very much determines how it "feels" during day to day use. Also, do you plan to do track days on these same ties, or do you have dedicated track tires? This should have a huge impact in the choice you make
NISMO does not make coilovers for the Z - they are just a matched set of springs and struts, no adjustable height, no adjustable dampening.

The Stance coilover has full height adjustablity, so unless some sort of funky bushing binding that I've never heard about was going on, dampner stroke issues were not the cause of how the car felt.
I considered the Stance coilovers, but I felt their was too much risk. I didn't get enough confidence in the review's posted, as good and well liked as they have been penned. In the end I felt better about paying more, that my idea of right and wrong was better taken care of by a system who's gene's I was well aware of and who's developement was handled by qualified people.

The car went straight, so alignment issues didn't come to mind, though the car was very willing to kick the butt out, moreso than most other Z's I am used to (he was on Cusco bars, so not adjustable out back). They very well could have been setup incorrectly (preload vs. bracket adjustments) - you're guess is as good as mine, they just all in all didn't feel "good" for lack of a technical term lol during the 10 minutes or so I was driving the car - the moving far more than the front during steering input, which gives you an unsettling feeling. The owner of the car "loved" them - my guess is he loved how low he was able to go, and so long as the car went right and left when asked to, it was his definition of "great", which is of course a big problem when researching any mod. Anyway, with a "true" coilover setup in the rear, my interest in really exploring them further just wasn't there - maybe if I get some time over the fall or winter I can get the car here, and a damper put on a local shock dyno for some testing, and see what makes em tick.

Turismo, curious,.....what about the D2's is motivating you to pull them and something else?
Damping?
Overall stiffness?
Quality (leaking, noises ect)?
Most cheap coilovers tend to be underdampned. Too much spring and poor shock control. Delivering that as the final product to control costs and keep profits up where your hoping to fool the unknowing into thinking the ride quality is "great, better then stock" is only fooling those that don't know any better, sadly the owners end up not knowing what they are missing. It could end their because, hey they are happy aren't they? No, it's a great car with owner's that deserve better.

Are zeals and stance the only two companies that make a true coilover? Noticing both coilover systems let you slam your amongst means, but zeal of course takes the win.

Well, I searched on here before I made my decision. And I concluded that the Stance where the best for my applications. I looked at the Cusco's, Jics, HKS and Pss9's(really considered these) but I wanted something capable of going to the track in. From the reviews I read, Stance seems to have a strong following here.
I went with the true coilover setup. I wanted something different so I can compare with my last two coilovers(Tein/D2's).

I have the RSR's and although they are comfortable I would look into the HKS Hipermax III's. they sound like they are even more comfortable on the street than the RSR's.

I have the GR+ Pros turismo. I like them a lot so far although the ride can be harsh on certain roads.
As far as handling goes, I think they feel great. I haven't autox'd again since my alignment and new tires but I'm pretty excited.

I believe they are. But the Zeals I heard are way to stiff for street useage.
