I must chime in here just to say what great aftersale service these guys @ JRZ HQ have.
Special thanks to Erik R. and his co-worker. Having some rattle at the back dampers lately I made an appointment in Uden a few weeks back. They testdrove the car and decided to change both the dampers. Ever since everything stays quit as it should At the Spa racetrack the dampers are set at 22 clicks in front and 20 in the back and at the Ring 10 clicks in front and 7 in the back. These set ups work fine for me. Very pleased with the suspension so far and all credits to Advevo for sharing this. |

Today I had a visit at the JRZ factory Uden (Netherlands), rear shocks had some issues which had to be resolved. Bushings had to be replaced (don`t know if that is the correct word in English)
Anyway, it was just 20 minutes of work. The shocks are really awesome, I still use the 2nd klick all around ( JRZ advises to use the same settings all around) The car is absolutely brilliant in road performance, it is very comfortable on bumpy roads yet tight in cornering at high speed, no nose diving at high speed breaking (note; this is only 2nd klick, while range goes tot 22 klicks !!) The car is overall very planted to the road no matter the circumstances. This is so impressive because it brings the two utter differences (comfort vs sportiness/tightness) in a stunning way together !! Last but not least; we had a personal guidance tour at the JRZ factory. What can I say; Stunning, no just awesome, absolutely amazing how these products are manufactured (handmade) and tested, the machinery and equipment which are being used is really only the best of the best If you are in the neighborhood you absolutely have to visit them !! Thank again to Mr Erik Ras and all the personal at JRZ for this wonderful experience, it makes you realize how special these dampers are under your own car, thanks for the outstanding service and follow up, this is the best I have ever seen (I have seen quit a few) and I really would recommend JRZ to everybody !! |

@ Romo
So you got a set that was loud, had them replaced, then they got loud again and had them modified at the factory, and now they are actually quiet? You also mentioned 2 clicks is comfortable and 1 click being almost 'too soft'. Would you say 1 click is softer than stock, about the same, or stiffer? And which spring set are your running? I find these shocks very interesting because of the simplicity of a single adjustment parameter. I'm not interested in figuring out 3-way adjustables just to have a lowered and stiff setup, that likely isn't optimized for the driving I'm doing. If these shocks + off the shelf eibach/hnr springs results in stock-like comfort + simple adjustability for a low price, with vastly improved body control and handling,... then sign me up. |

Low price is relative to one's income/budget. JRZ are high end both in quality and cost. Bottomline is you're going to get what you pay for.

I have upgraded the JRZ RS1 dampers. Settings are the same i only wanted to use race springs and high adjustable. But i did not want to change the original top mount to a camber plate which can make sound. I did not want to loose any comfort. The little noise whats there isn't coming from the shocks. It s the 2 bushes which hold the rear damper in place in the lower suspension arm. I have changed those too to the new ones. JRZ is always working on such small details!!!.
JRZ came with the perfect solution. See pics. Orginal top mount with race springs hight adjustable ---> PERFECT. Last edited by Advevo; 07-13-2012 at 06:24 PM.. |

FWIW, I'm running 9 off full soft at all four corners.
I also have a slightly used pair of Ground Control adjustable camber/caster plates for the 1M -- designed to be used with stock springs -- if anyone is interested. Neil |

Your settings are the same for street and track? Camber plates and dampers?

You can find my full reviews and write up thus far here.
http://www.m3post.com/forums/showthr...=632444&page=5 I run 4 clicks up front and 3 clicks out back from full soft for street use. Thing that amazes me the most really is how the set up is never harsh, over curbing, turtles, or the bumps at the Glen, which you are going over at some high speeds. The car remains flat, and predictable while never beating up the driver. Shows how well the damping is working. BTW, Im on 500/800 springs for those that have not visited this thread before. Last year I was at the Glen with KW Clubsports, which I though worked well at the track. As a comparison though, I was hitting an extra 20KM on the back straight this year, because I was going up the esses with much more confidence. I was also having to shift up into 4th or 5th in places that I did not last year because I was carrying much more speed into corners and out of them. Now I was running NT05s last year and RS3s this year, so that might have something to do with it as well. Overall, extremely happy with the set up. After, I just adjusted the shocks back to my street settings, and drove the 350KM home in comfort. Contact Bimmerworld if you guys are looking for the best dual set up out there IMO. I'll be at Mosport in August which is another fast track. __________________

JRZ does not run bump stops. This is why (direct quote from a JRZ engineer in Holland)

If you read Jan Zuijdijk's (of JRZ) book, he's got some pretty interesting ideas on how to make a damper perform, but many of them require over-the-top precision that require frequent service to keep the damper performing correctly. Fine for a race car, but some of the ideas he has are not appropriate for street car longevity.

James sums it up best. (not shocking)
Our Performance Center foreman has run JRZ TRIPLES on his daily for 3 years...not a problem.

Thats good to hear, another reason that the RS1s are perfect for a DD car.
They really do a great job of soaking up the bumps as well.

I have been to Willow Springs (the Big Track) once since installing the Jrz RS1 with springs and camber plates. I also had the dedicated track tire and wheels on with 275/35/18 Nitto Nto1's. The handling was superb. I had substantially less body roll, less nose diving under breaking and less squatting on hard exceleration. I had it set at 14 clicks front and 11 rear. I would highly recommend them as a great dd car suspension option. Getting the GC adjustable camber plates was a must for dialing in the camber and improving my track times.
