The JRZ shocks that we use are made specifically for the 350Z. The Non-remote resevoir DA shocks are about $3400 for a set. Then you need to add your own springs. If you are using T2 springs then you have to have a custom spring perch made for the front shocks, cost about $350. Otherwise they are a direct bolt on, and fit the OEM nissan upper shock mounts. Call Speedware Motorsports 425-869-5680 if you are interested in the JRZ's, they worked with JRZ to build the first set of 350Z shock for my car and also had the spring perches built.
The Motons are $5500 for the set of 4, they dont come with springs so you have to add that cost in as well.

The Moton club sport sytem is out now, here's a link. (in case the system scrambles the link it's 350zmotoring, search back to march of 05 in the autocross section for Moton ) http://www.350zmotoring.com/forums/s...ad.php?t=24459
TcKline has DA Koni's right now, they have seperate rebound and compression adjustability. But, they sure look like reworked twin tube SA's, hmmm. I hope they shortened the piston rods, at least in the front. http://www.tcklineracing.com/nonbmw.htm

Just FYI, Jerome, the "J" in JRZ, left JRZ and started Moton, that is why both JRZ and Moton shocks look very similar. All three founders of JRZ (cant rember the names of the "R" and "Z") came from Koni raceshocks....

The plan is to have a serious track setup wich is still streetable. I'm working hard to get consistent lap times this week-end at Putnam Park on my stock Z so we can have a future base line for the setup.

Using OEM spring locations, the setup will allow for some ride heigh adjustability.

If they use 50mm bodies in the front I already have lower spring mount's worked out.
And thank you jmark for the heads up.

The motons never came to surface. The TCKlines are what he used on his T2 350Z car, so they have TC's custom valving. They're similar to my truechoice but they're built in holland at the koni factory (since he placed a large enough order) thus they're much less expensive. Perhaps they're built better too since I've had problems with 3 out of my for truechoice shocks. Our local T2 driver has these as well. At $419, they're an outstanding value.
I agree with ALong, as long as you have the right shocks, the T2 springs are liveable on a daily basis (for a sporting driver). I was trying to work with the racers group on the JRZ's before I got my shocks but I got the impression that since I wasn't a rich porsche owner they weren't interested in doing busienss with me. The price ALong mentioned for the JRZ's seems like a great deal.

I just spoke with TcKline. This is the jest of the conversation.
The shocks are a double adjustable version of the SA shock design that are made by Koni in volume to TcKline specs. Internally they use the same construction as the SA's and have the same low pressure twin tube design. They differ, beside's the DA aspect, in that their valving rates have zero in common with the Koni SA shocks, they have a second grove cut in the front bodies that is 1" lower vs Koni SA's which feature a second grove that is 1/2" higher. When asked if they used shorter front piston shaft length's, he did not know the answer, pretty sure they are the same as Koni SA's in that regard. He mentioned that they've run their shock with spring rates as high as 800lbs.

What ever happened to Advanced Design? They used to offer DA dampers with custom Eibach springs, for around $400 apiece. I know they recieved very good reviews from several BMW and Sentra SE-R cup racers, but the website they used to have is no longer around. I shot an e-mail to Ground Control about them, but never recieved a response.

Which is also the reason they don't offer their sleave coilovers either.

As Mark metioned, I have been running the TC Kline / Koni shocks on my 350Z with the T2 spring / Sway bar combo. Before buying TC's shocks, I spent time on the phone with a friendly engineer from Koni discussing pros and cons of TC's sport-based shocks vs. some of their "race-only" applications. The engineer steered me towards the sport-based shocks because in real world testing, they are better able to deal with slop in the supension casued by stock rubber bushings than the "race-only" shocks.
I've been very satified with the valving and adjustment range on the shocks and think that they represent a great value.
