Date: Fri, 6 Aug 2004 13:13:46 -0700 (PDT) From: Chester Wong <chester_p_wong@yahoo.com> Subject: Reminder: Check the bolt holding the Koni in!!! On a side note with all this suspension talk, I noticed a clanging sound coming from the front of the car about a week or two ago. It sounded like I was dragging a chain and only happened when I went over bumps and other road imperfections. Couldn't find it the last time I took the wheel off to take a look but this morning, I crawled under the car and thought it was the steering rack bolts coming out. Nope...those were tight. Then I looked at the front strut touched the bolt/washer combo and was able to displace the washer up and down a significant amount. I replaced the front Konis a few months ago because they were leaking. I know Wayne and I torqued those struts into the housing, but I guess we didn't get the strut insert to completely bottom out in the housing. I was able to turn the bolt a significant amount before it tightened up. So...check them bolts! Also, doesn't anyone happen to know the torque for that bolt? Thanks, Chester =====

Date: Fri, 6 Aug 2004 16:43:55 EDT From: AVUSM3@aol.com Subject: RE: Shocks and Struts Rich - Bilsteins (at least the original style) will certainly raise the car with stock springs. I know this for a fact as I have done the installation a few times, and have accurate before and after measurements for my car in particular. In my case they raised the ride height about 1/2" all the way around. You are correct that there is about 750lbs on each corner of the car. You ask how the shocks could exert enough force to alter ride height? It's actually fairly simple. Lets say for example the stock spring rate at the front of the car is 200 lbs. load of 750 lbs/ 200 lbs per inch rate = 3.75 inches of travel (with no compression resistance from stock strut) The Bilsteins, unlike the stock Boges, have a substantial compression resistance due to the high pressure gas contained in the monotube design. If we assume for a minute that this compression resistance effectively causes a "compression" spring rate of 50lbs per inch, then the combined spring+bilstein calculation looks like: load of 750 lbs/ 250 lbs per inch rate = 3.00 inches of travel. While the actual numbers used here are approximations, I think its quite possible a shock/sturt with substantial compression resistance (from high pressure internal gas) can have a significant effect on ride height. I'm sure you would agree that the Bilsteins require significantly more force to compress (while off the car) than the stock units. It's this difference in compression resistance that causes the ride height change.

Run it with > stock springs and it 'will' raise the car one full inch in the front > (ask me how I know). This was not the case on the '97 M3 I did a few weeks ago. The Bilsteins did not raise the car 1" each corner, matter of fact, the ride height did not change. These were the latest Bilsteins (with the proper bumpstop direct from Bilstein). Frankly, I don't believe it can happen. In order for the car to raise 1" at each corner with the same exact springs, the new shocks/struts would have to have a lot of gas pressure in order to lift the car equally at each corner. If there was ~750 lbs. at each corner, the shock/strut would have to exert enough pressure to overcome that weight plus the assistance the spring provides at that point of travel. Since I can compress a Bilstein strut/shock by hand, I don't think that is too likely. It might have a small effect, but I find it hard to believe it was 1". Regards, Rich

I however did not have the 'latest' Bilsteins and my car sat higher (after the shock/struts install) and when I parked it next to John Stoj's stock suspended M3 and measured the gap, I could slide in an extra finger on the front tire well with Bilsteins/stock springs (compared to John Stoj's). I just measured my index finger this very second and its 3/4inch on the Fiskars scale. Guess I was mistaken, it not one full inch but more like 3/4th inch raise in the front when you install Bilstein on stock shocks. Well, I can understand you are not convinced, and I am sorry I cannot provide a reason as to "why it raises the car" here (unfortunately I am a finance geek and not an engineer). For more facts, call up Turnermotorsport and speak with Doug. I called him when I had this issue and he too agreed that a lot of customers complained about their cars being raised with Bilsteins/stock and even H&R OE Sport springs. Here is what Carl Buckland has to say: http://members.aol.com/agspeed/HRe36m3.htm Hope this helps.

I cannot, in good conscience, let this man's wasted two hours be to no avail. You can cut the top off of the stock housing in one minute with A very thin, 3 inch ceramic cutting disc (available at Home Depot), that would fit on the end of either a drill or a rotary air or electric cutting tool. mark.
