Hi guys,
has anybody an comparison value for the trunk lid? Found a replacement made out of carbon/ platic. Reseller says it weights 17.6lbs. Looks pretty much for me as the stock one is around 23.40 (parts catalog value) and 26lbs (real life) TRUNK LID Stock (Steel): 10.625 kg (23.40 lbs) (OC weighed his at 26.0 lbs) http://bmwfans.info/original/E92/Cou...1/ill-41_1638/ CF Vorsteiner lid: 14.9 lbs (OC Kid weighed it) Cost: $1362 Weight savings: 11.1 lbs (according to OC's numbers) cost/benefit: ~$123/lb http://www.vorsteiner.com/bmw/e92coupe-spoiler.html# http://www.redline-motorworks.com/product/9306%20BMV Thx!

E90 M3 weighed
I was at the track for a DE event Sunday and weighed my car on the chassis scale.
3,553 lbs w/no driver and 1/4 tank of fuel 2011 E90, manual trans, no sunroof, manual/cloth seats, no folding rear seats (no ZCW), ZCP. The car does have HK and NAV. I was pretty happy w/the weight of the car, as the car was optioned to save some weight. I was expecting more in the 3,600 lb range. -Brian |

Just had contact with Seibon Carbon and as it seems it's not really worth the effort to change the stock hood with a Seibon hood.
The trunk lids is ok for the price as the trunk lid is "just" $880 which is cheap compared to others. TRUNK LID Stock (Steel): 10.625 kg (23.40 lbs) (OC weighed his at 26.0 lbs) Seibon trunk lid (part: TL0708BMWE922D-C): 16lbs HOOD Stock (Al): 10.20 kg (22.47 lbs) Seibon hood (part: HD0708BMWE92M3-OE) 22lbs

As mentioned earlier, tire pressures can change things, and this is a street car so it will understeer. That being said have to agree with swamp that the weight you've removed should do little to the bias/handling of the car, but then again, on track at the "limit" it may be more noticeable. I am in pretty much your situation as I've shaved about as much as weight as possible and it's mostly from the rear, think camber plates, tire pressure, or square setup as think these would have a bigger effect on understeer than a few pounds up front, but am still open to suggestions as well:thumbsup

I stripped out the back to make it easier (more room) for me to remove the glue residue from the last tint job. I'm leaving it stripped out until the guy puts in new tint on the back window on Friday and then everything is going back in. The road noise is much louder than I expected and while there is no doubt that the car weighs less (the rear suspension is actually sitting higher), I can't justify the cost/benefit of leaving it this way. I'm going to get an oem mini 55 amp/hr battery and save 25lbs that way.

Additionally, carbon pieces like a hood are often sized for handling loads and durability which can further reduce its weight savings opportunity. Last edited by dmw16; 07-11-2013 at 07:02 AM.. |

+1 You can get plenty fast lap times at the track without doing any weight reductions. Tires and driver mod!

It comes down to laws of physics. The heavy end of an object will always move outwards under centrifugal force. |

There is more at play than this. There are also different spring rates, suspension geometry, available grip at each tire etc. And then there is an acceleration vector since one should be on the throttle throughout the turn in most cases if doing it right. It's nowhere near as simple as a rigid object experiencing uniform centrifugal force distribution.

What? Why do I need to take it easy? An oversimplified answer that comes to an incorrect conclusion is preferable how?

And I didn't say it was incorrect. I said it draws an incorrect conclusion because it is too oversimplified for this application. No one is denying centrifugal force = mv^2/r Do you just like to bicker or what's the deal here? Nothing I've posted is absurd in the slightest. Last edited by oldmanstyle; 11-25-2013 at 03:20 PM.. |

I just don't like people coming on here being sanctimonious pricks instead of providing actual content. And yeah, grammar and syntax is real important these days. I'm sure you're the type of guy that would shit on Einstein because he ended the sentence with a preposition and why add mass? It's a constant

And again I ask, why are you being obtuse for no good reason? I advise you to get over it as nothing I've posted here was out of line until you came in crying because you're apparently ok with incomplete explanations and misinformation. Quote:
That seems less out of line and condescending than your posts ITT, which are basically just whining at me for correctly elaborating on a misleading statement. So take a good look in the mirror before you continue this senseless derail that YOU started. |
