Date: Wed, 29 Mar 2006 08:50:19 -0500 From: kresener@aol.com Subject: Was Cams....Now Gears There was a discussion a couple weeks back about installing lower gears in the rear end and the effect it would have on the car's acceleration and I thought that would be a great way to gain some speed back that we've all lost on those e46 M3's. I've just about got myself convinced that that's what I need to do, quickly here before my next DE, and now the talk on cams surfaces. Am I understanding the gains of lower gears wrong, in that wouldn't I get the same boost in acceleration from gears rather than opening up my motor and putting cams in? Seems that gears is a less expensive option for the same net result? Kurt Resener '95 M3

#3. Found good source for 32 mm wrench (fan and inner tie rods) - from Michael, Dave

Date: Wed, 29 Mar 2006 09:09:59 -0500 From: "Michael, Dave" <Dave_Michael@maxtor.com> Subject: Found good source for 32 mm wrench (fan and inner tie rods) While perusing my local REI, I saw this tool, which looks like it would work well for not only the fan clutch, but also the inner tire rod ends (at the rack). Its intended for use on bicycle headsets and it costs only $14.00! Another bonus is that the other end will fit the new BMW oil filter housing nut. FWIW: I have NOT ordered or used it (I bought the $34.00 32mm wrench from Bav-Auto ;-( last year). http://www.rei.com/online/store/ProductDisplay?storeId=8000&catalogId=40 000008000&productId=47802840&parent_category_rn=4500918&vcat=REI_SSHP_CY CLING_TOC Dave 98 m3/4

(from either a parts yard or someone upgrading their auto to a 3.91) Although I dont have cams, I would say the gain from the Diff is a better bang for the $$. (they dont call it a "poor man's supercharger" for nothing.) That said, its not as if doing cams would be worthless after swapping diffs. Adding cams would still bump the power X amount regardless of the differential ratio. -Richard On 3/29/06, docwyte@comcast.net <docwyte@comcast.net> wrote: > > Date: Wed, 29 Mar 2006 14:06:44 +0000 > From: docwyte@comcast.net > Subject: Re: [E36M3] Was Cams....Now Gears > > I don't know if it'd be cheaper for gears, a 3.46 rear diff from > diffsonline.com is $1700 I think, then install... > > You'll gain acceleration all over with the diff, but will lose mpg... > > -------------- Original message -------------- > From: kresener@aol.com > > > Date: Wed, 29 Mar 2006 08:50:19 -0500 > > From: kresener@aol.com > > Subject: Was Cams....Now Gears > > > > There was a discussion a couple weeks back about installing lower gears > in the > > rear end and the effect it would have on the car's acceleration and I > thought > > that would be a great way to gain some speed back that we've all lost on > those > > e46 M3's. > > > > I've just about got myself convinced that that's what I need to do, > quickly here > > before my next DE, and now the talk on cams surfaces. > > > > Am I understanding the gains of lower gears wrong, in that wouldn't I > get the > > same boost in acceleration from gears rather than opening up my motor > and > > putting cams in? > > > > Seems that gears is a less expensive option for the same net result? > > > > Kurt Resener > > '95 M3 > > > > > > ************************************************* > > Please help support the E36M3 list by visiting our sponsors: > > > > Bimmerworld http://www.bimmerworld.com > > Turner Motorsport http://www.turnermotorsport.com > > Eurosport High Performance http://www.eurosporthighperformance.com > > Rogue Engineering http://www.rogueengineering.com > > Treehouse Racing http://www.treehouseracing.com > > Elephant Motorsports Inc. http://www.elephantmotorsports.com > > > > DIGEST INFORMATION: > > http://www.bmw-m.net/resources/digest_info.htm > > ************************************************* > > > > > > ************************************************* > Please help support the E36M3 list by visiting our sponsors: > > Bimmerworld http://www.bimmerworld.com > Turner Motorsport http://www.turnermotorsport.com > Eurosport High Performance http://www.eurosporthighperformance.com > Rogue Engineering http://www.rogueengineering.com > Treehouse Racing http://www.treehouseracing.com > Elephant Motorsports Inc. http://www.elephantmotorsports.com > > DIGEST INFORMATION: > http://www.bmw-m.net/resources/digest_info.htm > ************************************************* > > >

I've gotten 26MPG on the highway while averaging over 75MPH. :) I'm a big fan of my 3.46, but I do find myself wishing for a 6th gear from time to time when I'm cruising at 80MPH. The motor is turning around 3800RPM at that speed. The acceleration is great, but you get it at the expense of top speed in every gear. It's most noticeable on certain autox courses when I have to decide whether to shift or hold revs at redline. This is part of the reason why the Sunbelt cams, with the 7400RPM redline, are particularly attractive. Too bad house prices are keeping my fun spending in check!

NOW: 15mm each $45 bucks OBO Correction and thanks for your replies folks, I said these were 30 mm and where that is true by the box label, they are actually 15mm each, so I was wrong. H&R apparently puts total combined spacer width for reference on the box. I found this by searching H&R's website and actually measuring what I have. They list #3075725 for $95, so I think $45 obo plus shipping is fair especially considering you have to buy the wheel bolts extra, and I am throwing in 9 of them for you. BTW, I did check the part numbers on the edge of the spacers and verified them to match and be the correct part. From H&R website (http://www.hrsprings.com/site/index.html) listing for 95-99 M3, and below as well if you can read it. Let me know. I am putting these on ebay very soon.

These are unlike H&R part # 6075725 which Turner sells in that the latter bolt to hub and wheel to spacer, although they appear to be the same if you could somehow get the right wheels studs and press in female receptors, (not sure what to call them). The #3075725 is still hub-centric and work the same only that the stud passes through the spacer into the original hub. 9 longer wheel bolts are included, (cannot find the 10th one, sorry). Turner lists #6075725 for $179, and I have no idea what to ask for the #3075725, so I am offering to list for best 'reasonable' offer plus shipping $. If no body bites ebay it is, so please let me know ASAP. Paypal strongly preferred. Thanks, Patrick Goss 97 M3/4
