On this topic.... and I know there's no one simple answer... as the shape,
size, configuration, etc. of a windshield is going to make all the difference..
but in general...
What thickness are people using on their TR's? 1/4" 5/16"?
Secondly... I keep hearing about Plexiglass cracking... but overall....
wouldn't Plexiglass be the better choice? You can polish Plexiglass... Lexan,
on the other hand, is very unforgiving.
While Plex might crack on an impact, it is unlikely (seems to me) to create
projectiles.
What I'm getting at is... in the life of a windshield... if the impact is hard
enough to crack the plex... it's likely hard enough to damage lexan...
meanwhile... if you have lexan... you'll find yourself having to live with
scratches... during the life of the windshield.
One of the racers mentioned to me, that after losing it in a turn, the car
became enveloped in dust... and a track helper reached over and whiped down his
windshield, so that he could see before returning to the track..... this simple
wipe down... scratched his Lexan beyond repair.
So the question is... Lexan or Plex? and what thickness are people using?
