Very interested in the RS and RS Pro. Got anymore info and pics?

Honestly, I would love to have a set of triple or even quad adjustable JRZ but realisticly a set of double adjustable RS/RS Pro will be more than enough for my needs (10-12 track weekends and few autox per year) consider how expensive the regular JRZ are....

Here's the RS pro, rebound adjuster on the top of the shock shaft, and compression adjuster on the reservoir.



And heres the RS, rebound adjuster is on the top of the shock shaft, and rebound is on the bottom of the shock body.



These will cost quite a bit less than the motorsport line of shocks, but will still perform extremely well. I consider them a much better alternative to the similarly priced Ohlin Road & Track shocks.

mmmmm.... purty.....

Wow, this looks great!
So this is better than the Moton Clubsport?

If you're trying to gauge interest, I'm interested.

According to all the research I have done, and what the people at JRZ have told me, yes they are much better than the Clubsport's . I hope to also offer them at a better price than the Motons as well. I'll try to have something for you guys early next week in terms of pricing on the RS and RS Pro.

Next week I will have some diagrams for the Evo for you guys to look at. I will also have some shock dyno graphs for those who want to see the incredible adjustability of the JRZ shocks.

well, ok.

indeed, if you're trying to whip up interest, it's working.

are you working with anybody yet on spring rates and such? any track day test mules out there?

The PSS9s are a great hi-perf road platform. Think an upgraded adjustable, shorter MR system. With over double the stock spring rates they ride at least as well as stock. We drove 10hrs to a race - no problem. Their valving allows the shocks to be really supple over small bumps. They are a durable single adjustable system that you can drive daily and should require no maintenance.

For dedicated competition on r compound tires, they need some tweaking of spring rates and revalving, which Bilstein offers for a reasonable cost. They should be available soon.

Sorry to hi-jack the thread Max, I think the PSS9s appeal to a different market than the JRZs.

I have the Motons. It will be interesting for you to convince me that the JRZ's are a "much better" shock considering the founder of Moton left JRZ.

If the final product is similiar to your first picture above, the front shocks do not have camber adjustability at the upper lower strut bolt like the Motons. I find it to be a benefit for fitting wider wheels and tires. Will there be the option of quick disconnects? ($$$) What ID. size spring will the upper and lower spring perches accomidate? 2.25, 2.5, 60mm? What OD. is the main shaft? 22mm? Do the 90 degree lower shock body fittings move free or are they stationary allowing the line to take the bulk of suspension movement? What pressures will the external reservoirs hold?

How about US support for JRZ? I'm not refering to suppliers, respectfully.

I would caution anyone purchasing external reservoirs for street duty for 2 reasons. First, for the simple fact they require extensive care in the placement of the reservoir line. If you plan to locate the rear reservoir inside the trunk, imagine the hole that must be drilled if you do not have quick disconnects (and even if you do). Fortunately, the front struts do not necessarily need the quick disconnects, but are helpful during installation. Secondly, filling the reservoirs take additional equipment costing in upwards of $3-400. You can easily purchase the correct fittings, line, adapter, gauge, and fill up with nitrogen at your local weld supplies shop at half the cost, but if you want to add/adjust at the track, then plan on a tank and regulator. I spent over 30 hours mocking up/installing the external reservoirs on my Motons to find the optimal line placement. Like I said, this is a caution for the external reservoirs, not a review of JRZ in any way. Add in Penske with Moton and JRZ, and there you have it, the top shocks to bench mark against.

Also, I'd be interested to see what you come up with for the front pillow ball camber plates and rear top hats. Works custom machined some rears for me which came out perfect.

I must say that the RS Pro's look nice. Any recommended installation instructions/ placement that you can supply with the JRZ's would be very beneficial to the customer by taking out a lot of the guess work. Especially considering that this is primarily a race prepared shock.

Glad to see JRZ finally come on as an upper end shock supplier for the Evo!

Ok...is there a pool on how much these things are going to cost?

Put me down for $4200 for the set...not including custom valving.

Ok guys, hope you're in for the long haul cuz this is going to be a long post!!

Firstly, the picture I posted was of JRZs for the Evo 6, the evo 7 and 8 will in fact have the camber adjustability on the lower mounting bracket like the OEM, and as mentioned before, if there is an absense of the brake bracket I will make a special request for all of our sets to have it included. Quick disconnects are an option, and I will provide information on what I believe to be the best place to drill to mount them in the rear trunk. I also will have the option to mount the reservoirs to the rear shocks, like you see in formula cars for those people who want to save a bit of money, or simply do not want to drill into their cars. The JRZs can use a 2.5" spring, I will find out about 2.25" and 60mm. The shaft is the same 22mm as the Moton, in fact the design on both motorsport shocks is identical, it is the RS and RS pro that differ from the Clubsport line, not to say that the Moton design is in any sense bad, I simply feel the JRZs are superior for a couple reasons as I previously stated. For the rear shocks, the line is on a banjo swivel, allowing it to move freely as the suspension moves, the front is directly connected to the strut, because the line needs to go through a hole in the body, and if it were at a 90 degree right angle it would interfere with many other moving components in the wheel well, such as the driveshafts. The reservoirs will hold 100-300 PSI, the same as the Moton, not only does this have the benefit of less aeration, but it also adds a lifting force on that side of the car, just like adding stiffer springs. This allows you to test the affects of higher spring rates without having to install them, doing that you can test it, if you like it you can go ahead and change your spring rates to what would be better suited, this feature is what I'd call amazing.

US support for JRZ is wonderful, they have an official US branch The Racers Group who can rebuild, service, or revalve your JRZ shocks, although I believe these shocks will last longer than your car will .

I would like to say that running an external reservoir shock for a dual duty car is in my opinion one of the best favors you can do for yourself. Seeing as how these shocks are double adjustable, and calibratable via nitrogen pressure you can take it to the track, input your settings into the shocks, have them stiff, have the car react quickly, absorb bumps, but take its set like you would want, but on the way home you can readjust them so your dental work will remain safe, and your kidneys will remain functioning for quite some time! These really are race shocks, but do not be mistaken, they can be run on the street, the adjustments have enough range, they are reliable enough, they are definately sturdy enough, and they dont make any strange noises.

I will definately include full instructions, and hardware for these shocks once they are up for sale, I won't offer a half solution, in my opinion when I buy something I wan't something I wont have to run to the hardware store or to a machine shop to install, I want them to simply bolt on, and I will make sure to follow this principle with all the products I release in the future.

Hope to have answered all your questions!

I'll be testing all that stuff personally! I'll be testing the shocks at autox, and track days to give further recomendations for spring rates. You can even ask Richard my credentials.

One last question......Why in the h*ll did JRZ take so long? I inquired about JRZ's in Feb. and they had no plans to offer them for the US Evo anytime soon. It's too bad (for me), because it sounds like they have someone here on the evom board who will be an experienced supplier. Thanks for taking the time to answer most of my questions and concerns.

I plan to purchase the Evo 10, that is if it's still in the works. Hopefully JRZ can stay with the times and offer a shock package soon after the new platform's debut.

Dave

Hahahaha, ya, Moton usually is quick to release their products, but as you can see by the developement of the JRZ RS line, JRZ seems like the type to make sure everything is totally perfect before they release their product, not always the best for the consumer, but it pays off quite well in the end.

If you get that Evo 10 let me know, because I plan to still be doing this even around the time of its release in 5 years!!
