The seal ? Its not glued in with urethane glue ? How old was that windshield ? what year is your van ? I knocked mine loose with a lot less than you got lol ! It came loose as soon as I started beating on it - rain pouring in so I had a new windshield put in and kinda know the glass guy and he did alot of prep work prior to gluing the new one in and its still holding tight. I think glue gets old and brittle and comes apart. Now my truck roof is alot stronger than yours, yours is flexing like a honda accord roof and may just be moving to much for glue to hold and well glass dont flex well. Did you check GP audio, they say they sell SPL glass ?

I have seen plexi windshields as thick as 1" with toggle clamps all around. But all that would be $$$$.

Technically your not allowed to mod beyond the b pillar so brace it as much as you can from the b pillar back.

2009 the seal was still in great condition, It handled lots of flex fine just never hit 26 hz this hard before. It just turned to pure jello even with plywood on the roof.
The GP glass is not an option. That costs almost my whole system combined lol.

Consider taking some reinforcement off the roof to put less pressure on the glass. A guy up my way had to do this.

Or if that don't work could you weld in a sub frame to stiffen it up some ? Or you are not allowed to do that rules wise ?

its against the rules if they check but they only check at finals. I dont plan on driving half way around the country just to pay to meter.. I'll just get my name up for a couple official runs and thats it just to have it on file. The rest of my career will be demos.
was thinking of welding stuff or fiberglassing everything includiing the seal point as well.

if your roof is braced its going to stop hte roof from flexing at that point the glass is only going to crack close to its res frequency if the center of the roof is weakest brace it. looks lik the glass is breaking because the rood isn't rigid..

Ive been shopping 1" lexan, heard nothing but neg on plexi and agree that gp glass is buttrape.
Brace your roof
I would do steel plate over your 1/2" ply
It's just creating a pinch point when everything flexes then boop cracked
