Default Lexan weight savings?

87 trillion micrograms

see if you can get the lexan coated with the scratch guard stuff, lexan scratches really easily

Yeah if i end up buying lexan, it will be the good stuff.

I guess it's about half the weight of glass.

yep, half weight that is. (is it echoing..?)

btw. I think qrtrs are ok to be changed to lexan , but would guess side windows getting scrachy, if you ever use windows. Good coating is no real way to happiness, unfortunately, It'll get marks aswell. Of course, here such F40 style small opening in side windows would be so cool + you could get rid of side window mechnisms.

like this.

Regarding the sliding window- it would be very very cool but only on the right style car. My car is still too street to pull off anything crazy like that.

Most people with lexan windows also remove the regulator and motor - so that legitimately saves a bit of weight.

Replacing the quarter panel windows with lexan... that'll just save a few lbs (maybe 2 or 3).

18.5lbs, according to a spreadsheet created by an old-time rennlister who documented his weight reduction process: http://members.rennlist.com/dan10101/car_math.htm.
