So I am towing my 450i to New Hampshire Sunday. Just finished installing a home made 1/4" lexan windshield ( 2 piece folding), and a 1 piece rear window bent to the curve of the rear roll bar. I was wondering if I should tow the 450i backwards, as the rear window seems much stronger to me. I don't want to flex the windshield towing it forwards. I can flex it by hand a little bit. But the rear window feels like it could stop a bullet. Any suggestions, how does everybody else tow that have windshields?
