Windshield Crack

Winshields on most cars with unibody construction are pretty important in structural ridgity, and a breakage will certainly spread on the track, sometimes very quickly and can impair safe viewing through it. Not to mention that even tempered glass cubed shards are still very sharp, remove themselves off the plastic inner layers and the windshield could remove itself from the car if sufficiently motivated.

If I was a safety inspector, I wouldn't pass it. I am not though, so maybe email John @ Evil Genius, its his call.

To answer your question, yes, cracks are legal.  We have several cracks and it had no problem in tech.

We have a spare windshield, but it would require a new seal which isn't cheap, so we stuck with the cracked one.  Old cars like our Z need the seal for the windshield to stay in.  Newer cars use sealant only.

Use your judgment. If it's a little crack of the sort the CHP will use as an excuse to stop you and look for the weed (not from experience, just an example....), you'll probably be fine. If the whole thing is being held together by the glue surrounding the rearview mirror, you may have an issue. You can always email me with pix and I'll consult the tech inspectors for you.

Yup. And if you replace it with Lexan, you'll probably drop at least 20 pounds off your car and still be compliant with all pertinent Lemons safety regs.

Because, you know, that 20 pounds is all that's keeping you from winning this race
