For those that haven't seen them, the advantage of the Bimmerworld backing plates over the TMS pictured by Steve is that they don't require the bearings to be pulled. You just cut and unbolt the stock plates and slide in the new ones. Very slick. Rich D said it nicely: > I can think of many things that seem overpriced until you start figuring out > what it costs to produce, limited market demand, labor costs, tool & equipment > costs, etc. Sure, there are all kinds of homebrew solutions possible. It comes down to your skills, resources and inclination. And how many hours you want to spend on a project. I know I can't make backing plates, so I bought the Bimmerworld kit. Well worth it for me. On the other hand I just spent a ridiculous amount of time trying to figure out how to mount my new 6 point harnesses in the very best way. No way I wanted to have someone else do it. So, you pays your money and you makes your choice! Neil 96 M3

Date: Wed, 19 Jun 2002 18:04:45 -0400 From: "Gary A. Preece" <gapreece@entreky.net> Subject: lightweight battery Just FYI...no connection etc. Dyna-batt has their batteries 15% off through the internet. I put one in my 95 M3 and it fit perfectly under the cover. My stock battery weighed 46 lbs. and my new one weighed 14.5 lbs. according to my bathroom scale. Now if I could lose 31.5 lbs. around the waist, as well, my car would be faster! Gary Preece

These are not mellow, cruise around the track days either :-). The only reason I have to replace them now is due to the radial cracking. I think this is caused by excessive heat. If I can get rid of the cracking the rotors will last a LONG time, there's almost no other wear. I think you'll be fine on any course with a high quality track pad. I run a variety of tracks and the PF90's are excellent everywhere. If you're shopping track-only pads I'd recommend the PF97's (PF90 replacement) and I've heard very good things about the Hawk HT-10's.

I absolutely belive in cryo treating rotors, personal experience as well as other local track junkie input has me convinced of it's value. I don't know if the ducting will prevent the radial cracks either, sure hope so.

Any real downsides for a car without a ton of electric options? -peterg ------------------------------------------------------------------------------------------- This message was sent using HiSpeed Technologies Webmail. http://www.hispeed.com

Then you're just cooling >the inside face of the disc, which will lead to more stress and worse >cracking. huh? Tack weld a tube to the backing plate, exactly as Bimmerworld has seam-welded a tube to theirs, and clamp a hose (from a brake duct) to it. If you locate it in the same spot, it will shoot air into the hub vents. there's no magic to the BW pieces. compare: stock http://www.bimmerworld.com/images/e36bp1.JPG bimmerworld http://www.bimmerworld.com/images/e36bp2.JPG I also agree that $245 is outrageous for what could be a simple $80 part. That'll inspire me to try a few DIY options for basically free. Powdercoat, stainless steel, who cares. Same deal as $300 micropolished shifters I guess. andy r. 98 m3/2

#10. Bimmerworld ducts on a daily driver? - from Rob
Top
Date: Wed, 19 Jun 2002 19:54:23 -0600 From: "Rob" <motor@cadvision.com> Subject: Bimmerworld ducts on a daily driver? Does anyone run the Bimmerworld M3 duct kit on a street car? Is hose removal required to drive on the street and get anything near full steering lock? Can someone please explain to me what the "flanges" are? It looks like they might help attach the hose to the existing brake duct but I can't tell. I have the BMP cooling ducts that go in place of the OEM driving lights (yeah right!) so I assume I could connect the Bimmerworld hose to them? Thanks, Rob - spinnin' my S50B32 to 7600rpm :)
