#1. Re: [E36M3]Does "toe" affect traction? - from Robert Liu

Sean, The slip angle for maximum cornering force changes depending on normal load. During cornering, weight transfer means the normal load is different inside to outside. Ackerman steer and initial toe settings can be very useful for optimizing the cornering performance of a vehicle. Sorry, I'm a vehicle dynamics nut. ps. Fixed my misfire problem.. fouled spark plugs. Thanks for all the help!

This topic came up on the list a long LONG time ago, I was somewhat interested in performing the same conversion. Big problem is the costs - you have to buy a new steering wheel (obviously) and the airbag that fits in there, the airbags are not the same size between the two steering wheels. Total was something above $1000. Second problem that mentioned was installation: either DIY or good luck finding a shop that would be willing to work on the airbag system because of potential liability issues there. Like I said, this came up a durn long time ago, this is what I remember. Mebbe somebody else on the list has some more info. I skipped it, left well enough alone. Andrej '97 M3

#5. fix for broken sway bar brackets - from Dorffer, Rich
Top
Date: Tue, 13 Feb 2001 14:57:30 -0500 From: "Dorffer, Rich" <RDORFFER@CleIndians.com> Subject: fix for broken sway bar brackets David states > Please do not shoot the messenger on this tip. I was told by someone at Energy Suspension that the critical thing most bushings need is a grease retention feature. He said that most bushings could be greatly improved by cutting a groove(s) in your existing bushing with either a thread tap, dremel tool, soldering iron, or what ever else you can think of. This is not my idea, but I do think it is likely to be a great improvement. Not as nice as greasable though. If you have the UUC sway bars, then they should have come with "rifled" grooves in the polyurethane bushings which appear to be doing a very good job retaining the lithium grease I loaded them up with upon installation in my 95 M3. Not as nice as greasable and "rifled" grooves but definitely better than no "rifled" grooves at all. I have considered adding a grease fitting to my bushings but will not do anything until I hear the pesky buggars squeaking. Regards, Rich 95 M3

I have installed > what I believe to be a cure for the front bracket breakage. I believe the > cause of the problem is that most sway bar bushings do not retain grease > very well. They sure don't. But I'm not convinced that's really the failure mode. The bars have one hell of a lot of leverage on those bushings. My RD bars have never squeaked, and moved reasonably freely. I regreased the bushings as a preventative measure. The front mounting brackets both cracked anyway. :( As an experiment I've just installed the original BMW rubber front bushings from the 850 CSi, which match the RD bar's 27mm size. My theory is that even with an aftermarket suspension, rubber mounting the swaybars isn't going to degrade handling in any perceptible way. We'll see how that pans out in practice. > I have broken the rear mounts as well...and am only partially finished with > the fix for the rear. I have welded in the Turner motorsports reinforcing > brackets. Me too, but the TMS reinforcements weren't yet available, so my welder used some steel plate he had lying around. I've also just fitted stock BMW rubber mounts here. Since I didn't find a BMW part in the exact 22mm diameter needed, I relieved the 20mm M3 mount to fit. Again, we'll see how this works out. > One last tip for those of you who have not experienced problems with > aftermarket brackets and bars yet.

#9. Energy suspensions - rear bushings - from Barrett Nicholas
Top
Date: 13 Feb 2001 15:07:27 CST From: Barrett Nicholas <barrett.nicholas@usa.net> Subject: Energy suspensions - rear bushings I spoke with someone at Energy Suspensions about their lack of a direct application for the rear e36 sway bar bushings. Their response was that they're currently up to their eyeballs, but that if someone who lives in the San Clemente, California area wanted to give them a call toward the beginning of March, they'd work with them in developing something that would work with the rear bars -and that person would get a free set. So, if you live in that area, maybe make a note to give them a ring next month and we'll all benefit from it.
