In my quest to lighten the turbo, I am thinking the doors with window glass, motors etc must be heavy. What are the options for lightening this? I have thought of a couple, but don't know if they work or are legal:
1) put 924 manual windows in and maybe use plexiglass.
2) they make a 'slider' window where half the window slides forward, but the plexiglass is fixed. Is this legal per PCA rules?
3) other options? The car is daily driven, so some sort of window is needed.
Any ideas or experience would be appreciated.
