E46 Weight Reduction

Hey guys,

I'm trying to remove some weight from my car to squeeze out any extra power I can for free. The spare tyre was a good reduction, but I'm still trying to find other things I can do to reduce the weight. I have been doing some research on YouTube and found a couple of guys who are really experienced in this area and made some pretty significant improvements on the car's 0-100 speed. I think I'm definitely going through with their mod on my 2004 M Sport 318i, as the 2.0L just isn't getting me up to speed quick enough. Does anybody have any experience with the kind of work in this video? Maybe somebody could give me some tips from their experience so that I don't run into any snags along the way.



Cheers!

Yeah it is, not sure on the stock weight I want to say 3500 and it was weighed on a Full tank, and i always have all my necessary tools with me which could account for another 30lbs.

the curb weight for my 328 is supposedly like 3,256 pounds according to this
http://www.cars.com/bmw/328/2000/exp...s/?revid=33177

so if i had all your mods and an empty tank i bet i could get under 3000 pounds without me in the car

Hmmm...I found that mine is supposed to weigh 3020lbs based on this. http://www.autoevolution.com/engine/...1998-323i.html

I didn't see the curb weight for mine using the link in your last post.

For the record, i weighed mine at a truck weigh station, not sure how accurate they are now.

I have one of those stations on the edge of my town. What did you have to do to use it? Do you know someone?
I'd feel weird driving up and asking

OP, I have to say that I haven't driven a 318i but imagine that Tuscan is right. You're still going to end up with a relatively slow car. You could lose 200 lbs., say, and shave .1 secs off your 0-60 time, but is it worth getting caught in the Outback with a flat tire, no spare or jack?

One of our long-lost Fanatics got stranded in the Outback in his e46. It was night time and pretty frightening for him. I remember well that when he woke up in the morning, his car was surrounded by Kangeroos. Not knowing why, he tossed out his spare quart of oil, and sure enough they all went for it and he could escape out one side of the car to get back to Fanatics and write about it.

Whatever you do, don't remove that spare quart of oil. I keep one in my passenger side door pocket. Even though the Kangaroo population has been kept in check here in New Jersey ever since the population outbreak in'09, the squirrels here have seemingly developed a similar 'pack hunting' approach to survival. Other species are learning also. Just last month I was chased by a flock of Ring-necked Pheasants. I have dings all over my car from that episode. You might end up with dingos.

Be careful...don't bother...and if you do bother, please do the 'risk/reward' calculation.
