We have a couple sets left now that the team is no more, if you're interested. These are definitely not entry level.
Where can I find more info and spec about the JRZ Adjustable coilovers? never heard about them before.

^They are suspension company that builds setups fr club racing up to full race specs. They are almost the same as Moton.

KWs do not ride harsh, but handle very well. Just don't get agressive with the compression damping setting. I've had JIC on my '94 Miata in the past and the KWs were far less damaging to the ride, but that was when JIC wanted to put 10k front springs on a 2200 lb car.

One of the reasons it's hard to say what is best for the street is a) everyone has a different objective, b) almost none of us have had the chance to test all these systems, c) street performance is a bit of an oxy-moron. You can be on the street with a killer setup and be "beat" by somebody with a crappy setup just because they are willing to take more chances than you. Darwinism at work.

If the OP is looking for a performance-oriented system that can make back-road romps more fun, not punish you on the daily drive, but still play well for solo or track work on street tires, then KW, Bilstein, and Ohlins are all good bets. As others have stated, be careful with the spring rates - I wouldn't reccomend going much beyond the stock KW/PSS9 rates for the above described duty.

Stance, JIC, Tein will all work just fine as well, although it sounds like perhaps Stance got a little aggresive on the spring rates. I've heard good things about JICs with the "soft" spring rate on the new Miata, which shares the suspension design with our car. The racers here may cringe a little, but if you are not racing then it doesn't matter if the setup doesn't have the pedigree and/or is a little slower.

Personally speaking, I can't reccomend the KWs enough. Geat dual-use setup.

Good point. I don't want to spend more than $1500 so the KW's are a little out of my range.

I found a set of JIC-Magic FLT-TAR (soft setup) for $1,580 . Would that be a good option?

The spring rates are 8k front, 5k rear. (450lb/281lb)

If you go with JIC, I'd suggest getting the 8k/5k springs, as opposed to 10k/7k. But, I've not run the JICs on an RX-8 so take my opinion with a grain of salt. However, the higher springs would work better with R compounds if you ever want to do that.

Just a tip, KW's are crazy expensive in USA for some reason. Money can be saved if you order them from Germany.

I doubt it'd make sense once you figure in shipping. That's a big, heavy box.

I will definately go with the lower spring rates. It only make sense for a street car.

Like I said...Your not tracking the car. Just get some cheap Megans. You'll be happy with them.

I don't just want to lower my car. I still want my car to handle well.

My point is, how much of a background do you have with coilovers? Because if the answer is none. You will still like the Megans, and they will handle well for you.

Honestly I don't think you will be pushing your car enough to make buying the PSS9's or something else in that price range worth it for you.

Listen I dont feels like reading this whole thing. GTG to take care of something right now. But My opinion Just get what ever coilover you can afford with DAMPER adjustment and 6kg-4kg springs(something soft). Lots of kits come with 10kg springs and up, and thats to stiff for the street imo. and thats it folks. I prob should have read the entire thread someone prob said this already.

Topgear your my boy and all. But the Megans are definitely cheap. But not shitty.
I've hit some pretty big pot holes here in NYC, traked the car, auto-crossed, MT raced, etc etc etc, and never did I have ONE problem with the Megans. Why they get a bad rap IDK. It is what it is.

Quik experience. I had Super Street Teins on my 240sx, and hit a pot hole. All the liquid inside the shock came out and it blew. They were only 3months old. I've had my Megans now for 3 years. I've thought about getting Stance coilovers, just because im a lable **** sometimes, but I just cant find a good enough reason too.

I've started with the basics to get an idea of what I wanted down the road...
They are not worthy after you have put some harsh mileage on them IMO. I use KW's and will be switching to Ohlins.

Judging by what everyone has mentioned, I would go with Stance GR or KW's if you think about spending a little more money. But like TOP GEAR has mentioned, you might not notice to much of a difference if you are not pushing the car....

I agree with you, IMO, I think megans are more forgiving, IDK. Maybe it's just me.

i have heard one thing about the stance set up. That is if you already have the big Racing Beat front end links, then the coilover will rub agaisnt it--the end link has to be ground down so it will clear. Anyone else seen this?
I am thinking about getting the stances but havent ordered yet.

^Not always true. I have the RB Front sways with RB endlinks. And they do not rub on my Stance GR+ Coilovers.

^I'm pretty sure the one who posted pics was on some PT Sway bars. When he set them to full stiff, the endlinks would rub. But if it was at the softest, or middle setting, there was no rubbing.
