ELEPHANT RACING Rgruppe Monterey Project

The windows are in the car. Front windshield remains glass but the side and rear windows have been replaced with polycarbonate to reduce weight. Replacing the glass with polycarbonate shaved about 29 lbs. In addition the manual window lifts have been removed to save an additional 10 lbs. Total savings 39 lbs.

That's a valuable 39 lbs because it sits high on the car. Eliminating that weight from the canopy lowers the center of mass and will reduce body roll, dive and squat.

Polycarbonate side windows can be run legally in POC and PCA track events in the closed position to improve aerodynamics. Glass windows must be in the down position.

	Rear polycarbonate window requires clips and rigid aluminum stays to prevent blowout or blow in. Rear window is lightweight 1/8" and saves about 15 lbs!
	Detail of lower clips and stays. Clips are designed to go over stock window trim without damaging the delicate aluminum.
	Detail of upper clips and stays. The lightweight stays are made of aluminum yet are very rigid. Stays and clips have a combined weight of about 1 pound.
	Side windows are also polycarbonate. Rear quarters are 1/8" and save 2 lbs each. Door windows are thicker and more rigid to prevent blow out, yet still save 5 lbs each.
	Window lifts have been eliminated saving 5 lbs per door. Nylon straps provide the ability to raise and lower window. Inner door panel is not yet installed but will have a hole with grommet to allow the nylon loop through.
