Lexan windows for A2s. Where? Need weight loss.

I've seen A2 cars with Lexan quarter panel windows. I'm anticipating that my car is going to get bumped to B prepared where I will be forced to race stripped out race ready Corvettes. My local sactioning body is doing this in the name of fairness. Even though my machine never scored higher than 2nd place and all races were one by .1 of a second. Hmph...
Sorry for the rant. Anyhoo. My only hope to be anything that remotely resembles competition to these vettes it to loose weight and putt on wider rubber.
Any weight loss tips would be greatly appreciated.
