I have removed over 200kg of weight from my car now. I did write down the weight of every standard part that I removed or replaced and kept a running total but unfortunately mislaid the piece of paper that I had written each individual item on. I'm pretty sure that I haven't lost it and it will turn up one day when I clear out some boxes of parts I have or something and then I can post all the details on here!

I'm running the manual rack too. There are some pictures of the rack on its own, off the car, in my project thread, if that is any help to you?

Thanks for that link - bizarrely I had not seen that write up before on my own car!
