At the track I use an "EZ-Up", 9 1/2 feet square, which I got at Wal-Mart a few years ago. I forget how much I paid, maybe $150 or so. It collapses into a pouch that even fits cross-ways in my trunk - but storage in your coupe is quite a bit tighter. EZ-Ups come in lots of sizes, and also in both light (aluminum frame) and heavy duty (steel frame) versions. My light duty version has been fine for this kind of use. Neil 96 M3

On those funny OBI-II cars with FOUR sensors (or so I'm told... gasp!) it could be a totally different story. Anyway... The crow's foot just made it very easy since you could position a ratchet on it in any of several angles to get leverage on the thing. I'm sure it could be done with regular tools in a pinch. BTW, I asked the guy at the tools counter for a O2 sensor adapter without mentioning what kind of car or anything and got the crows foot. I guess they're all the same size 'cause it fit perfectly. -- Ron Katona '95 M3 - BSP #06 Mel Silva wrote: > I don't need to do this today, but...

They are medium-soft rubber all the way. Compressible with your fingers, but not by much. I would have expected them to have a noticeable effect on the ride of the car if the car was riding on them, but I am still convinced that there was very little difference in the quality of the ride between my car (untrimmed Bilstein / H&R 29910) and Lowell's (trimmed Bilstein / Dinan springs). The rear bumpstops are external and made of a similar, slightly harder rubber. >>>>As for riding on the untrimmed bumpstops, while I haven't opened mine up yet those that I have experience with on other Bilsteins consist of a compressible foam. So riding on the initial portion of the bumpstop is not like having a solid suspension, only one with a different (i.e. stiffer) spring rate. Obviously if you compress the bumpstop far enough it will reach a point where it will compress no further but that should be (my guess) and inch or better in travel. If you have the H&R race springs you may well have the suspension effectively bottomed out but I wouldn't really know until I see how the bumpstops are actually constructed.<<<< __________________________________________________ Do You Yahoo!?

#4. Re: [E36M3] Door panel cover separation - from Mark Siismets

Date: Fri, 15 Jun 2001 11:46:53 -0700 (PDT) From: Mark Siismets <msiismets@yahoo.com> Subject: Re: [E36M3] Door panel cover separation Thanks to all who replied to my post about door panel cover separation. I spoke with the service manager at Momentum BMW here in Houston about this problem, and he said it's fairly common in the South due to heat and humidity. Separation is covered while the car is in warranty, but unfortunately my car is 6.5 years old with 75k miles. He referred me to a repairman that Momentum uses for such repairs. This guy has repaired mostly 5-series cars with this problem, but has also seen it on 3-series cars. He said that the vinyl tends to shrink over time, and the adhesive used by BMW doesn't fare well when exposed to heat and humidity. He re-covers panels with vinyls and leathers he obtains through BMW US. Evidently these are better suited to southern climates, and are constructed with a different backing material. He's tried re-applying adhesives to existing panels with little success. The apparent shrinkage of the cover material makes this sort of repair very difficult. Despite that, I may still try adding some adhesive from the back-side of the panel (as suggested by several list members) and see what happens. By the way, the price of a new panel for a '95 M3 coupe is $290 less whatever CCA discount you can get (at Momentum BMW it is 15%; I've seen others advertise more in Roundel). This repairman will recover a panel for $125, and he'll do the repairs at your home or office. Thanks again for the responses.

This isn't unheard of, and in fact BMW introduced a reinforcing plate between the strut hat and the tower sheet metal starting with the 96 M3. However I've only heard of cases of cracking involving racecars with super high rate springs, solid bushings, etc. First question, are the reinforcing plates there? It's possible to forget them when reassembling struts to the car (ask me how I know...). If they aren't in place, you should be having a talk with whoever installed them. Not that it helps you at this point, but given the recent discussions about Bilsteins and their bump stop issue, I have to wonder whether that may have played a part here. > I need help, the car is under warranty but it won't fly with this. > suspension I am going out of my mind! As you've figured out for yourself, there's no easy solution. You're going to have to have sheet metal welded in to fix the crack, anywhere from a piece to a whole strut tower, depending. Find a body shop you trust and put in in their hands. However even with your aftermarket suspension, you have nothing to lose by talking to your local dealer first. Neil 96 M3

#7. Part numbers for passenger trim - from Luis Veras
Top
Date: Fri, 15 Jun 2001 19:40:58 -0400 From: "Luis Veras" <veras@tricom.net> Subject: Part numbers for passenger trim I hope I can explain myself correctly... A couple of weeks ago I wanted to change the passenger side panel that has the A/C vent windows. But while looking closer into it, the glove box itself also has some damages; it's bent due to the heat and sun, so it doesn't close properly. If I fall into a pothole, the glove box will even pop itself open. So, I'd like to get the part numbers for the entire glove box panel, including the part that has the passenger side windows and the lock for the glove compartment. I've included a picture taken from page 513-2 of the E36 Bentley Manual, and put in a red frame the exact parts that I want. I know the part that has the A/C vent windows costs around $30, but dunno about the part that has the glove box. I'd like to get the part numbers, please. Thanks in advance for your help.

#10. RE: [E36M3] Bilstein bumpstops Again => Warrantee Update - from Tom Tice
Top
Date: Fri, 15 Jun 2001 22:44:16 -0400 From: "Tom Tice" <tetice@triad.rr.com> Subject: RE: [E36M3] Bilstein bumpstops Again => Warrantee Update Well last night I actually opened up my Bilsteins and I agree with John's description below of the Bumpstops - medium soft rubber which is quite a bit firmer than the foam types I have seen before. However their diameter is quite a bit smaller as well would have an effect on their compressibility. They are just a hair under 3 inches long and the upper portion is somewhat hollow which would also increase its initial compressibility. As for the warrantee. I spoke to the Bilstein East Coast sales guy today. I trust that he would give me the straight scoop as I have personally worked with him in the past (to put on joint BMW club/Korman open house autocross when he worked for Ray Korman). By the way he is a BMW enthusiast and also drives a E36 M3. In any event, his view is that trimming the bumpstops by 20 or 25 mm would have no effect on the warrantee - it would be judged like any other warrantee claim. You are really only removing about 1/3 of the bumpstop and the remaining bumpstop would adequately protect the shock from bottoming out type damage. Furthermore, his view was that trim or no trim, the effect on the ride quality with H&R sports would not be perceptible as it would only behave like an incrementally increased spring rate. He reminded me that the M3 represents about 900 lbs at each corner and the force of 900 lbs would have no problem compressing the rubber bump stop. My opinion is that I suspect this is true with respect to small undulations in the road or bumps like those associated with expansion joints. I suspect that one would notice a difference on jarring bumps such as a good sized pothole and that a rim bending type of pothole would be just as rough for either case as it fully compresses the bumpstop. The "ride quality" will still primarily depend on the valving of the struts and the spring rates. Since my car is on jackstands and the struts are lying on my bench, I see no harm in removing 1/3 of the bumpstop in case it actually helps. If they were already on my car, I'd seriously consider if it was worth the effort. Tom Tice '98 M3/4 '99 540/6 > > I've seen and felt the bumpstops - my friend Lowell trimmed his.
