Excellent question, I was curious myself. I managed to carefully extricate a factory quarter window and compare the glass version to the Lexan version directly (see pics below). The factory windows use a LOT of heavy urethane to seal them in, but no rivets. I used some dense (but light) adhesive backed foam tape from the Home Depot Racing Warehouse in place of the urethane which I scraped off. The rivets are pretty light and I had to drill a hole to put them in, so I think it likely all washes out. Each side window is about 184 square inches, so overall swapping glass to Lexan (assuming it's all the same thickness) saves about 2.83 grams per square inch. What a terrible mixed-unit way to do this, but here we go. The hatch glass is about 1,800 square inches, so ~5,094 grams saved there. The little "peep glass" thing in the back of the hatch is about 288 square inches, so another ~815 grams saved there. If you were going to just swap out the glass for Lexan, it looks like you would save around 6,500 grams or 14lbs.What would you estimate the weight savings at?
Here are the Insight ratios:Looking great!
What final drive did you end up using? The Fit one? I think the Fit has a 4.6 FD if I remember right. I don't know what the Insight stock FD is.
The gauge is one of these from Perfect Tuning:Two questions.
What is the Red LED Guage showing? I see the Blue is RPM, Yellow is AFR, but I can't make out the red. Also, what guage is it? Never seen that before.
Are you going to run the wheel skirts while racing?
I guess that was three questions! lol
That's quite impressive. I dig the sound also.I took her to the Dyno last week, here is a quick video the shop posted of the run:
Here are the numbers from the 3 runs:

I also weighed the car as it sits, and it weighs in at 1460 lbs with about a quarter tank of fuel. I was able to balance the front wheel loads left and right to a perfect match using the adjustable spring perches.
