The question that then comes to mind is whether to go with the M3 offset bushings or stay with stock. With the H&R/Koni setup what then is the advised toe setting for either case? Will staying with spec setting keep tire wear optimized? >From previous discussions only the caster is affected by the offset bushing so I would assume toe should be the same for either but I'm not sure. -Kevin ---------------------------------------------------------------- This e-mail communication is confidential and is intended only for the individual(s) or entity named above and others who have been specifically authorized to receive it.

I've actually measured a handful including OE '95 M3 springs and the rate is all but a wash. H&R sport springs are really only a "lowering" spring since they don't increase the actual spring rate but rather change the free length to droop the ride height. The OE springs rely on the bump stop for increased rate under heavy travel. So if you have the OE bump stops with lowering springs you'll be riding on them MUCH sooner in the suspension travel. Rob mentioned this as well, I'm just adding another data point. My 318ti with OE bump stops (taller than OE e36 M3 stops) actually sat on the bump stops under static load with H&R sport springs. They were promptly removed and changed to M3 versions which are shorter. Additionally, the harshness you feel may well be the result of the Bilstein dampers, not the springs. Bilstein sport shocks/struts have a reputation for being stiffer than the OE sport hardware. I can back this up from my own experience with OE sport, Bilstein Sport and Koni SA dampers all used on stock as well as H&R sport springs. The Bilstein set-up was by far more harsh on the street than either the OE sport or Koni dampers. I live in Michigan where the roads are crap so ride quality is something I've plenty familiar with! Hope that helps. Cheers, Chet Dawes -----Original Message----- From: Brian Ruiz <[EMAIL PROTECTED]> To: UUC Digest <[email protected]> Subject: <E36> M3 spring comparo Hey all, I currently have a set of HR _OE_ Sport springs on my 95 M3, and they are unbelievably harsh. The Sport springs I had on my old E36 325 weren't this bad, I don't know what is up with these currently on my car...I guess they're a poor match for the Bilstein sport shocks. In any event, I was wondering what opinions were on the HR Sport springs versus the Eibach Pro-Kits. My experience with the HR Sport springs leads me in that direction, but I do think that perhaps with the more agressive nature of the M3, the Sport springs might be a bit harsher than they were on my old 325 on broken/pothole ridden streets. The car is only street driven, but I will probably do one or two driving schools in the near future.

My guess is that they will either a) not fit b) will be loose. If I were swapping springs between those two cars I'd make sure you swap springs along with the strut bearings that correspond. And then there's kind of a can of worms as to the front control arm geometry which is also different, the later cars have the outer ball joint offset to increase caster. The earlier cars accomplish this with the offset control arm bushing (like the 95 M3). Carlos. 98 M3 __________________________________ Yahoo!

Upper spring perches are cheap; strut mounts are much more expensive. Paul, Like Carlos, I'd expect the M3 springs to be shorter in free length. FWIW; my '95 M3 front springs had 3 pink (or faded red) paint stripes on each coil. Not sure on the rears. In my measurements, the front springs between a sport 318ti and M3 had virtually identical spring rates (+/- 2%). This was a bit of a surprise to me but I have total confidence in the measurement method and instruments used and the data does not lie. The H&R sport springs I also compared were right in line too. The only major variable between them was the free length.

They also both get the occasional (and ubiquitous) "alien text", with which we can live. The OBC has the little recessed dimple to push to change various settings. But I never learned how to adjust the units on the more primative clock/temp thingies. So today I actually pulled out the owner's manual (yes, we have one for each car) to see how to do it. Great, BMW says it is via a switch on the back of the unit, and refers the owner to the dealer for the adjustment.

Message-ID: <[EMAIL PROTECTED]> There are cracks on the main circuit board internal to the unit. It is changing these parameters not because of the settings of the switch on the unit's backside, but because of these hairline cracks. You can test this by pressing on the face of the unit in the center with moderate pressure. A cracked unit will change before your eyes. The unit is quite easy to dismantle if you are careful and look the unit over carefully. The display is simply a pressure fit on the contact strip. Use younger eyes than mine and a magnifying glass to find the cracks, solder and a short piece of bare wire to bridge the cracks.
