A slightly different version of this post appeared in another digest. I thought that it might be of interest to readers here, as well.
I recently installed an H&R coilover system on my E36 M3, and wanted to share some first impressions. I will write a much more detailed, technical article later, as time permits.
The H&R coilover system for the E36 M3 is a very new design, which was specifically made for the car. In fact, it is one of the ONLY front struts that are specifically made for the E36 M3! Even the Bilstein and Koni struts are made from donor stock parts. The front struts are adjustable coilovers. The struts and the rear shocks are designed after the de Carbon (not the brandname, but the de Carbon principle). They are a high preassure, monotube gas shock. SAME as the Bilsteins that many of the BMW after market tuners prefer, but not made by Bilstein OR Koni. Made my H&R.
In fact, H&R makes the tubes with threads that Koni is using for ITS adjustable coilovers (Koni makes its own shocks).
H&R makes all their own struts and springs and shocks, in house, by Germans.
I will write about the installation, set up, and subjective impressions of my H&R's as soon as I can, but I will say this for now: The system, in conjunction with the RD swaybars, is more than I had ever hoped for! It is very firm, but SMOOOOTH. I can just FLY over very rough terrain. I feel every little undulation, but it is NOT harsh. No bouncing, jarring, or vibration. Just firm, supple feel. I like it MUCH more for the rough roads of Utah than I had expected, and on the track (in this case, an autocross), I don't know what more I could ask for. Neutral handling, quick turn in, smooth over rough transitions (where others were scraping), no body roll. I think that they are the perfect compromise. More to come.
Regards to all,
