When I had to get my windshield replaced, the shop I used tried to find a Lexus OEM windshield. It was something like $900 for just the glass. An aftermarket windshield was $270, out the door installed. I went with the latter because I wasn't prepared to spend more than $1k.
FWIW, I didn't notice a difference in sound at all.
When I did some digging I do remember Lexus using thicker than normal glass to achieve more sound deadening. Whether aftermarket glass for the car replicated this or not, I don't know.
I can't answer your question regarding the Celsior, but this is my 2c on the topic.
At the time ours was replaced through Safelite they had multiple options available. All DOT approved though there was thick glass available. The PPG I chose was stated to be the equal to the factory glass. One key attribute was the clarity. The one they took off was from a China supplier and the optical properties were pretty poor. Can be some juggling to get a noise resistant glass yet also to balance the optical properties.
Notice the Toyota Celsior is more fully optioned with upgrades over American badged LS400...
Am interested to learn if anyone knows what differences, if any, exist between the 1995- 2000 Celsior and LS400 windshields...
With Celsior being Japanese, and your car US, there is bound to be a difference due to different safety standards of the two countries. Now, I don't know what those differences are, but since they apply to all cars sold in their respective countries, they should not be too hard to find.
I think that all safety car glass in the US has to be laminated - sandwiched between two layers of plastic (?) so that in the case of an accident, it does NOT spill. It only cracks and stays together, protected by lamination. (Same in Canada, I believe)
In Europe I think they want the glass to spill everywhere, like little marbles, with no large chunks left over. I guess, they believe there is less chance of an injury that way and it may be easier to recover victims from the car.
So different standards, different glass. Could be illegal to put a glass intended for, say, EU, in a US car.
First, am NOT recommending purchasing auto glass from Safelite...
One nearby so decided to visit and inquire as to why only one P.N., when there are two glass thicknesses....and which thickness would they be providing for my 1999 LS400...
Not an unreasonable inquiry.
After about 10 minutes the guy at the desk looked up and figured out I was there as a prospective customer.
After explaining to stooge #1 that I was seeking clarification on which glass thickness they were offering, he deferred to his boss.
Stooge #2 asked for all of the information again because stooge #1 was apparently incapable of conveying the information.
A real Izzy Moreno type who could not tell me glass thickness of their windshield and, moreover did not offer to find out and get back to me.
A real F U attitude.
So based on forum member comments, it is best to avoid aftermarket glass.
Lexus glass thickness information;
Windshield glass thickness 1998 2000 LS400 is 5.3 mm.
