Weight reduction

What's some good ways to make a e36 318is (european version) and a 323i 4-door lighter. I would guess the weight reduction techniques will be the same on both cars right?

Yeah, just start taking things out, gut the trunk, remove the spare tire, remove the seats that you don't need, remove the A/C.

If you want to spend money get carbon or fibreglass body panels, racing seats lighter wheels/tires, etc...

By pulling the back seat out, and spare wheel, will it make really that much differance in me actually feeling it?

Probably not, the spare tire is like 20kg, and the back seat is pretty light.
think about it this way, how well can you feel the difference in your car when you have a passenger next to you, as opposed to driving alone?

Ahh, yes, good point, I actually can feel the differance, but only really on inclines, and maybe, maybe a little in acceleration.

Probarly not worthwhile in the end to remove a bunch of stuff to make the car slightly lighter.

If you're racing and every tenth of a second counts, then sure, but to remove a lot of the practicality of your car for a barely noticable difference isn't worth it to me.

Like you can feel it, but you have to either remove a lot of stuff, or spend a bit of money for lighter parts.

I say either go all out, or not at all. Reducing the cars weight by 40kg won't do anything to noticable. So, if you do go for weight reduction, go all out.
seats, gut truck, spare, a/c, heater, blower motor, all vents, door panels, carpet etc.

imo, just leave it. the discomfort of having a stripped car is not worth it compared to the .2s 1/4 mile or whatever you'll get

Actually reducing weight on the 318 is the best modification you can do. The engine is underpowered for the weight of the car. I've done some moderate weight reduction and I'd have to say that it handles and accelerates significantly better. I'm actually happy with the power ouput now whereas I was not when I first had the car in stock form.

List of weight reduction mods...

- removed front aux fan
- replaced both front seats w/ Corbeau racing seats
- removed amp, speakers, speaker boxes
- removed door panel insulations
- trunk insulations and trunk carpet
- spare tire
- replaced side mirrors w/ non-motorized plastic mirrors
- replaced bukly airbox w/ k&n filter

I've probably ripped out a tonne of other crap, but I forget what else I've removed.

I've found replacing the seats with racing seats made the most noticeable improvement, especially if your stock seats are heated and electric. Removing the rear seats will also make a huge difference. However, it all depends on how far you're willing to go. I still need my AC, so that's not going out.
