On this subject I'm 100% with John (JL222), having us modify on side window, especially the drivers side windows to lexan is just dumb, dumb! This is one of the reasons why I'm ending my Land Speed racing, (other reaons are also because of running out of money after 18 years of racing), I can see the need to replace any rear window that are tempered glass with lexan, but doing this to the side windows will present engineering problems to design for cars like my Avanti and even if you could make a side rollup window, it may cause a safety problem it you can't release the window when trying to open the drivers door from the inside in an emergency (fire). Or it may end up at hight speed above 200mph just sucking out the entire side window because of it flexing, so in my case I'm ending my racing so I won't have to worry about this dumb rule. I'm on the "Coupe/sedan rules committee" but only the chairman was allowed to vote on this issue. So I think it will be a problem at high speed with cars blowing their windows out from the suction at high speed. In all the 18 years of racing at Bonnevile
I have only seen one car blow it side window out which did require a lot of time picking up the glasss, but I have seen 10 or more cars blowing out the rear window at over 200 mph, so I do support making us use lexan for the rear windows, which is what I did and bolted it into the rear of the car. My car is heading to the Studebaker Musuem next June so I don't need to worry about this crazy rule for 2012, thanks for your time, Dave
