Forged Performance: JRZ RS1 Coilovers **Review** and Press Release

Does the adjuster change the compression or rebound? Or is it a quasi system that affects both compression and rebound? A shock dyno plot would be good to see, but

The adjuster changes both rebound and compression simultaneously. They are valved where the rebound increases and decreases at a slightly greater rate than compression as adjustments are made. It's well thought out and engineered.

urvokbm is an unknown quantity at this point
Default Sounds GREAT...

But $4,000 ???? Based on your driving experience can you elaborate on how this system is $3,000 better than most setups? It would have to corner like an F1 car and cruise like a Maybach for me to even consider spending that kind of cash.

Those two goals don't really go hand in hand. (Which I'm syre you're obviously aware of.)

If i had the money i would get some JRZ coilovers, but i would get the 2 or 3 way adjustable coilovers and have them revalved a little.

Urvokbm, thank you for the question. The JRZ's are definitely geared towards the individual that does a dozen or more track days each year, but still daily drives the car on the street. JRZ used to only build dampers for professional motorsports applications and even today, all JRZ shocks are still manufactured in a small workshop in the Netherlands where each unit is built and assembled by hand. If you compare the top motorsport brands of dampers you will find that JRZ are priced very competitively.

Unlike a number of the entry level brands, our setup is designed 100% complete with aluminum CNC machined top hats front and rear, and a full true coilover for the rear, rather than an inboard spring with spindle mounted shock. We also include motorsport main springs and helper springs witih divider plates. We purchase the springs separately and the 8 springs (4 main 4 helper) we use are $750 alone. The full coilover setup gives much better spring control and is in direct connection to the spindle.

For those that are looking to lower their car and mostly driving on the street, the JRZ might arguably be overkill. But it's the best shock out there, hands down and I've tried almost every brand out there. The differences between the JRZ's and others is immediately apparent even on street driven car.

With respect to the number of adjustments and number of clicks, the marketing trend these days is more is better. But in the real world, I would prefer 5 clicks and 1 adjustment knob that work REALLY well, vs. 32 clicks, and 4 knobs that don't really make as much of a difference. At the end of the day, the proof is always in the laptime, and with the JRZ's we go faster and faster than all others.

I will see if Bryan@JRZ can chime in with some additional comments. One great things about owning JRZ shocks is the direct access the owners get to JRZ's top engineering staff in the USA. I can't tell you how many times I've called Bryan at 7:00am on a Sunday while on track and he gladly assists with setup and technical questions so we can maximize the performance from our setup.

Thank you ,

SA

I think you have to be serious enthusiast to appreciate quality and performance of JRZ coil overs. If you don't appreciate the difference between high quality motorsports damper and lower quality production damper it's not going to be good investment for you.

I spent $5000 on JRZ Clubsport setup and it was by far the best modification on my 370z. The range of dampening is incredible and unlike some dampers where its hard to tell if you are gettin any increase or decrease in dampening, compression, etc The JRZs make tuning your car easy! Too much dive at the track? Put more bump up front and nose stays planted. I can essentially tune the car with the shocks in ways no other cheap damper would allow.

Crazy thing is these dampers are so good that I get away with running 1000 lbs springs upfront on the street. The car rides smooth and controlled. On freeway ruts etc the car doesn't go airborne either. I can literally hear the dampers obsorbing shock and then pushing tires back to the ground.

This looks like excellent entry level JRZ package for our cars! Anyone who is true enthusiast can't go wrong with this package. Thanks to guys at Forged for offering this setup!
