Just gonna leave the electric ones in for now Ryan, prob go to "windy" windows when I can be arsed to change them over.
Rush - roof (inc cross members) saves over 20kgs
boot inc spoiler and polycarb saved 20kgs, so there's 40kgs.
If I went full out with the hole saw, got all the loom stripped down and did a few other bits I could get it to 775kg's I reckon. I'll save that for another year
