Date: Fri, 15 Apr 2005 11:39:39 -0800 From: "Som Naderi" <som@dimensionracing.com> Subject: Re: Soft steering... Zachary, I got the alignment done when I put new tires on. I had the problem for about 1 or 2 k before the new tires, and have had the problem for about 1 or 2k after the new tires/alignment. Thanks for the idea, though... it's one more thing to add to the list of what the problem *isn't*... * Not the tires... :) Here's a question... could worn control arm bushings cause this problem? I wouldn't think so because it seems they only control up/down movements. I was wondering if maybe the bushings on the KMac C/C plates had gone soft... which would explain why things were stiff after the first week or two after the suspension install. Maybe something with the plates/bushings has gone loose and is moving/flexing too much? I don't know how this would affect the steering only, though, considering I had the front end aligned twice within a month of each other -- once after the tires, then again after I put the new tie rods on. The camber/castor hadn't changed and I would imagine if there was much movement from the plates then I would have major alignment issues after a month. This is driving me nuts (no pun intended)... Anyone live in the San Diego (Del Mar) area and want to come by this weekend and drive my car (and maybe let me take their's around the block)? I've been driving it for more than 5 months like this and I'm starting to get those thoughts -- maybe the car is fine and it's *supposed* to feel like this. - Som >--- Som Naderi <som@dimensionracing.com> wrote: >> What else could it be??? >> >> * Not power steering fluid... >> * Not the tie rods... >> * Not the castor... > >just a hunch -- could the change in alignment which >would then change the contact patch of the tire be the >culprit? > >on every car i've had, when i put new tires on, the >steering feels much lighter for a time. of course, >there is "stuff" on new tires that may contribute to >this, but there is also a difference between the shape >of the tires when they're new and when they're "broken >in" to the particular geometry of the suspension. > >there is a similar situation in play here, just with >tires worn one "way" that are then put in a different >(alignment) situation. > >-zs

Som, Something that has not been mentioned yet is the Power Steering pump output. Seems to me I recall some sort of pressure relief/regulation built into the system that usually fails by not giving enough Power Steering effort. Perhaps yours is sticking in the over Power Steering mode. Just a thought....

Jay, My castor is in the 6 degree range... I just don't remember exactly where. I want to say around the 6.2-6.3 area. If 6.6 degrees isn't causing you problems, then I can't imagine 0.4 degrees less would cause this overly squishy feel. What else could it be??? * Not power steering fluid... * Not the tie rods... * Not the castor... I checked the steering rack bolts and they were quite tight. Also (as I mentioned in the other post) there wasn't any freeplay between the rack/pinion, so... * Not (likely) the steering rack... I thought *maybe* it was the ride height on the coilovers. I had them set to practically the lowest setting up until a couple days ago. I thought maybe the struts didn't have enough travel and maybe the car was riding the springs too much (which would explain the sloppy feel of the car... which I'm attributing to whatever this problem is with the steering). I raised the front height about 5/8" and the problem hasn't changed. So... * Not the ride height... What else affects the steering?? As for Thunderhill, my car is white and it'll be number "00". I'll be working on the safety truck when I'm not driving, and we usually stage around the med-building... so look for me there. :) I REALLY hope to have this problem fixed by then... - Som - Wants his steering back!

After a few sets of the S03s, the PS2s are my new favorite street tire. Not as harsh-feeling as the S03s, absolutely phenomenal in the wet and they perform incredibly well (with correct air pressure) on track when you're too lazy to change to your track wheels. ;) My personal take is that they out perform the S03s in every aspect. Of course, YMMV. =) Jonathan L. ----Original Message Follows---- From: m3bro@hotmail.com I am on th edge of buying new summer tires and what to get some of the lists opinions: (max perf. category) Bridgestone Potenza S-03 PP Goodyear Eagle F1 GS-D3 Kumho ECSTA MX lastly the Yokohama AVS ES100 (ultra high perf. category) (these are cheap) FYI - Tire Rack is offering a $100 off a purchase of four for most Bridgestone models.

#5. Adjust rear Camber / Toe? - from Mo Karamat
Top
Date: Sat, 16 Apr 2005 09:01:47 -0400 From: Mo Karamat <karamatm@optonline.net> Subject: Adjust rear Camber / Toe? Dear Group, Hello, I was using the Fastrax guage on my e36, and realized that the camber on my rear passenger side is a LOT more negative than the driver side.. I looked in the Bentley manual, and it does not say how to adjust it.. Is it done by adjusting the little bolts that have the scale on them on the lower control arms? or is that for Toe? Thanks Mo 98 m3/4

It has an eccentric and after it is loosened, you should be able to see the effect. In my Bentley, on p. 330-10, fig. 18, its not the lower shock bolt marked by the arrow, but the bolt that secures the lower control arm, just above the jack plate. Good luck. FWIW, I have a 95 with stock springs/bilsteins and ended up with 2deg each side. > -----Original Message----- > From: Mo Karamat [mailto:karamatm@optonline.net] > Sent: Saturday, April 16, 2005 9:07 AM > To: E36M3 > Subject: [E36M3] Adjust rear Camber / Toe? > > > Date: Sat, 16 Apr 2005 09:01:47 -0400 > From: Mo Karamat <karamatm@optonline.net> > Subject: Adjust rear Camber / Toe? > > Dear Group, > > Hello, I was using the Fastrax guage on my e36, and > realized that the > camber on my rear passenger side is a LOT more negative than > the driver > side..

Date: Sat, 16 Apr 2005 13:51:00 -0700 From: "Chris Teague" <cteague@cox.net> Subject: Re: [E36M3] Adjust rear Camber / Toe? Mo, The outer lower control arm bolt (with the scale) can be rotated to adjust camber. When you change the camber, the toe will change some also. More camber will add more toe. The toe is adjusted by the 3 bolts holding on the trailing arm bracket to the body of the car. These are at the front of the trailing arm. It's easy to adjust the toe, but a real pain to get correct, since there aren't any markings to guide you. So I make some ahead of time with a pencil. Careful not to let the bracket move as you snug the 3 bolts.

#8. Notchy shifter - from j. helffrich

Date: Sat, 16 Apr 2005 17:49:08 -0700 (PDT) From: "j. helffrich" <girolamous@yahoo.com> Subject: Notchy shifter Hi All, I know a lot of people have complained about the notchy shifter problem in M3s in the past, but I have never seen a resolution of the problem. Does anyone know how to fix this? I have tried changing to Redline and putting in a short shift kit, but sometimes I have to really force my '97 M3 into first from neutral. Any suggestions?

Some have success with RedLine, some like me with Royal Purple. It's a finicky tranny for sure. Give it a shot and let us know how it works.

Any damages will cause a misalignment of the transmission and will make shifting into some gears difficult.
