I'll flesh this out as I have more to say about this project.
CSL stands for Coupe Sports Lightweight.
BMW's official CSL models were the E9 CSL and the E46 M3 CSL
The stock E31 is CS, but not L—this is what I would like to work on.
My goals are to lose at least a few hundred pounds from my 1991 BMW 850i without turning it into a hacked up racecar. I believe there is weight to be lost which will not only make the car snappier, but should also reduce consumption of gas, brakes, suspension items, etc.
The CSL Project: Intro, Goals, etc.
Baseline...
http://www.e31.net says my car should weigh 1790 kg, unladen.
My trip to the Highway 1 weigh scales revealed a weight of ~1860 kg.
This gives me an approximate weight-to-power ratio of 13.67 lbs/HP.
This is without me in the car . . .
I currently weigh around 90 kg and will be trying to get that down to 80 over the summer.
I figure this is a fairly accurate reading, +/- 5 kg, when you factor in gas, heavier wheels, and some junk in my trunk!
Phase One: Preliminary Easy Rear lightening
Today, I removed:
- Rear seats and all armrest stuff in between
- Rear seat belts and sunshade
- Spare tire & Jack
- Tools
- CD Changer
- Trunk trim

Head units don't come much lighter than this baby! Solid state digital media all the way...
Exhaust Details
Center Resonator replaced with a pair of Magnaflow SS 14445's

This is how heavy and thick the stock stuff is:
Motivation
I have this emblem sitting in my workshop.
I will not put it on the car until I hit 3600 lbs.
