Nitron R3 Honest review?
Does anyone here have experience with nitron 3 ways. Just ordered a set and I am curious how they compare to other high end brands such as MCS, JRZ, MOTON. The spring rates we chose were 800/400 true rear coilover setup for my f82 M4cs.

Any updates on your end? How does it compare to stock CS suspension?

That is an extremely soft rear coilover spring rate. Wheel rates are around F 752 lbf/in and R 262 lbf/in. F/R ratio is 2.87. An MCS or Moton or Ohlins TTX setup with a F 800 lbf/in would have a R 700-741 lbf/in coilover spring rate or wheel rates of F 752 lbf/in and R 459-493 lbf/in. F/R ratio is 1.52-1.63 vs. your 2.87 - bias is way too much understeer. Stock spring rates are F 185 lbf/in and R 575 lbf/in rear divorced which are wheel rates of F 174 lbf/in and R 221 lbf/in. F/R ratio is 0.787. However, BMW uses the bump stops to limit travel so max rates are higher when bump stops are engaged. On my f82, I’m currently running MCS 2WR with F/R 700/1100 lbf/in (divorced rear) and am converting to F/R 1000/900 lbf/in (rear coilover). I also have MCS 2WR on my e92 M3 and f22 m240ix.
Nitron is a high-end motorsport damper that competes directly with MCS, Ohlins, Moton, Intrax and JRZ. Advantage of MCS, Moton and JRZ is the remote reservoir pressure can be varied (MCS is 100-275 psi) which is an additional setup variable. Only negative I’ve read (no personal experience) is Nitron has a higher failure rate. I do not know if this is true. |

I don't have the R3's but I've been running the Nitron R1's for about a year now and I absolutely love them. They transformed the car completely and I think it rides 100x better than stock. I did not want to go too crazy w/ the spring rates as I was DDing the car the time. I attached my build sheet. What I told them was I wanted something that will have fun carving the canyons with some track duty a few times a year. They set me up where I turn the dial 2 times for track all around and then 2 times back for my "normal" setup.
Highly recommend Nitrons.

A F/R 685/913 lbf/in will definitely improve the ability to rotate the car. I’ve tried 600/800, 600/900, 700/900, 700/1000 and 700/1100 on my MCS 2WR dampers. 600/900 and 700/1000 improved turn-in and balance midcorner compared to 700/900. A 600/900 lbf/in (or 110/160 N/mm = 628/913 lbf/in) will have improved balance over a 685/913 but if your car is primarily driven on the street the 685/913, or even 628/800 (better street ride quality), would work well on the street and still perform well on track. |

The car previously had a set of KW V3 coil-overs; the difference is night and day. Additionally, I have converted all the suspension arms over to SPL parts. Between the revised suspension geometry and Nitron system, the car has been completely transformed. I can now feel each wheel independently maintain traction over uneven road surfaces. The way the car settles after hitting a bump is completely different than the KW system I previously had. Rather than bouncing multiple times causing the vehicle to be unstable, the nitrons simply absorb the bump settling the car instantaneously. It was a bizarre feeling as I went from clenching my teeth while going over potholes to being pleasantly surprised by the compliant nature of the vehicle. The car has almost no body roll and handles like a full-on-track car that's surprisingly pleasant to drive on the street. In terms of spring rates, I have not noticed any significant understeer. This could be the result of implementing the full suite of SPL arms coupled with the aggressive track alignment.
