Kinda of a PITA to pull out though... About 45 lbs, based on the unit I took out of my race car. The sunroof itself is actually very easy to pull out. What's hard is sealing the opening afterwards. Unless you do some serious bodywork and eliminate the panel entirely, it will leak at the gap because the sealing mechanism used by the sunroof mechanism is now gone.

There is a tradeoff here. I recall, generally, that on cars like ours, removing 10 lbs is roughly a 1HP equivalent gain. There are second order affects: breaking, suspension. Performance and wear. In bicycle (non pro) racing there is a rough rule of thumb regarding cost per gram for value of the reduction in weight. I don't remember the formula. Application of this to real life ... I really want the Jim Conforti cam kit et al in my car. For the price of the kit installed I could do a lot of carbon fibre replacement. I might really like to do both. If I can't do both or if I might need to stage these changes where do you start. -- =========================== georgercarrjr@earthlink.net

Replacing steel parts with CF has to have a deleterious effect on crash integrity. As much as I idolize Chapman and his ideals, I'd be hesitant to monkey too much with the bits keeping me in one piece. I'd go with the JC cam kit (or the Sunbelt cams I'm hearing about on bimmerforums) before I'd go CF. JMHO.

But none of the differences are significant for anything but messageboard coupe vs sedan flamewars. I've lost all the emails with the numbers, except for these below, so take that for what it's worth: > Dynamic stiffness (measured in Hz, higher is better) > > E46 328i 29.8 > M coupe 29.2 > E36/2 29.2 > E39 29.0 > E36/4 28.3 > M roadster 18.4 > E36 cabrio 16.6 Bimmer Mag December 1998 andy r. 98 m3/2 >Actually I remember reading an old Roundel article which gave the e36 >stiffness specs and >I remember the coupe being rated as stiffer.

Date: Fri, 20 May 2005 20:58:04 -0700 From: "tom eby" <thomaseby@hotmail.com> Subject: Brake Lights Always On Is this a failure mode of the Brake Light Switch; fails normally closed? I've had the classic alert pop up on occasion, but not recently, and I've never changed out the switch. I'm out of town and Bentley schematics got left behind. A quick search of the archives didn't yield anything with a symptom of brake lights always on (key turned to "on" position). . . perhaps I should try tracking down a new switch. Any thoughts on this odd failure? Please reply direct, I'm on digest. -tom eby 96 m3 74 04 --
