Considering that these dampers are one of the ones I'm debating about, I am hoping that JRZ will be able to sort out some of these noise issues.

I have not had much time to use the car these past few days, but I got about 150KM on them today.
A little back ground, I have had Dinan springs, KW CS, and Moton SS on this car. I daily drive it, and its my track monster, which sees about 8-12 events a year typically. The roads in Toronto are horrid, especially in the downtown core where I live. The RS1s so far have been fantastic and the best suspension I have had on the car. They do a great job at soaking up the big and small bumps on the road while not feeling harsh at all. Im running 500/800 combo, I would def not go stiffer if you drive on bad streets though, I think its the limit unless you have high tolerance. I had initially set the front and rear at 3/3 clicks from full soft and stiffened it up a little and the ride got even better, hitting the sweet zone I guess. The car turns in and stay flat beautifully through a corner, really makes it effortless almost. Its hard to describe, but it almost makes the car feel lighter then it is, especially through fast speed corners. I do have some noise from one front shock, but I knew that was a possibility and James@Bimmerworld told me beforehand about it and they will be replaced/fixed, so not worried about it. My first track day on them will be April 1st. Im running -2.5 camber up front, -1.9 out back. 0 toe up front and 1/16th in the rear. Dropped about 1" all the way around. So far very happy with the set up, but need some more time on it. Big thanks to the guys at Bimmerworld. Excellent service and support.

Update from my end.
JRZ has addressed the noise problem that was present in some of the initial batch of RS1 shocks. They sent replacement shocks and all is well. Really appreciate JRZ and Bimmerworld's support. Neil |

Neil,
IRRC your car is a DD and you were concerned about ride quality and ground clearance in addition to better track performance. Are you still happy with the spring rates you chose? How much drop did you end up with? I’m looking at these shocks for my DD and I’m trying to determine if your spring choices and settings will work for me. From your posts I’ve read, I think so. I want the spring rates to strike a good balance between street & track and I don’t want an extreme drop. I don’t want be dragging the front end over driveways and speedbumps and really don’t want to tip toe around every hazard. I’m thinking a ½” drop will be good enough for me. I’m also wondering if you are running your track camber settings on the street and how that is affecting tire wear and straight line braking performance. |

Currently running 3 degrees camber in front and 2.2 in back. O toe in front and a bit of toe-in in rear. Haven't yet put a lot of miles on with these settings, but I expect tire wear will be ok. As you probably know, it's the combination of camber and toe that eats up tires. Neil |

For occassional track days, maybe some auto-x, and mostly recreational driving, any suggestions based on these options? I'll probably have the car lowered just slightly. |

Finaly I`ve been able to schedule an apointment on 05-05 for replacement JRZ RS 1 damperset.
There are some changes made compared to the 1st set, the new set has a different piston inside what should solve the noise. The olde piston had shims which produced the rattling sounds. Got the info straight from Mr Ras from JRZ. I`m looking forward to see how it is working and driving......... |

I had my JRZ RS1 set up installed a few weeks ago with Eibach Prokit springs and with GC 1M street adjustable camber plates. I followed the Advevo suspension strategy. Currently running 2.5 front, 0 toe, 2.0 rear .15 toe. I go to the track on 5/9 to test it out. I currently have 11 clicks squared. I have a set of dedicated tire/wheel set up for the track which is Apex 10/18 E25 squared and Nitto Nt01 275/35/18. There is no rubbing at all and looking forward for some good results at the track.

My replacements should be here next week. Glad to see that JRZ was active about solving the issue.
I think my drivers front shock is in the worst shape, I can't adjust the rebound anymore on it.

Update;
Last saturday I had the 1st JRZ RS1 damperset replaced, too much noise and sounds, this was not the way it was intended. There couldn`t be a greater difference. 1 All noises ands sounds are gone 2 It is smooth as butter (2nd klick), maybe even too soft (20 more klicks to go :-)) The 1st damperset on the 1st klick was far more uncomfortable compared to the 2nd klick new set, for daily driving not (understatement) the best setting ( but already on the 1st klick softer was impossible) I will have to make some experiments and see what setting will suit me and the the car for dd the best. For now I`m happy those terrible sounds are gone. Thanks to JRZ for great service and follow up !! |

Keep in mind the softest setup isn't always the best feeling. There is a window for a given chassis and spring set that is correct. Just like a car can be rough because the dampers are way turned up (overdamped), it can be underdamped also.

+1 A few more klicks wouldn`t harm the comfort at all I think. It will improve the feel of the car, but as I said, it will take some training and experiments to figure that out. |

I am glad everything is solved. These shocks are awesome. I am very happy with them done several track days and did some laps on the Nurburgring. It s one of the best compromises between road and track.

Big thanks to Bimmerworld and JRZ. Got 4 new replacement shocks yesterday. Will be installed next Tuesday.
I have 4 track days in June, including 2 days at Watkins Glen, so I'll have good feedback.

By now you all should have gotten in a few track days with your JRZs, so please post your reviews.
