I don't mean to beat a dead horse, but I want to re-emphasize again how important it is to get OEM glass and not the aftermarket stuff. In addition to rain sensors (if your car has them), all LSes have heated wiper parks (e.g., there is a little heating element where the wiper sits to melt snow, etc.). I don't have any personal experience with how aftermarket glass manufacturers handle these features, but why take a chance?
Unless you specifically ask for OEM glass, you will get cheaper aftermarket glass, especially when you consider the aftermarket glass is usually about 25-50% of the cost of the OEM glass. However, you get what you pay for. A friend's LS was at the dealer to replace the inside rear-view mirror under warranty and they ended up breaking the windshield during the replacement (duh!). The dealership, wanting to do a fix as cheaply as possible (since they were paying for it) put in this crappy Pilkington windshield instead of a Carlite, and you can absolutely see a difference. The Pilkington windshield has noticeable ripples in the glass that are very annoying, and the heated wiper park elements do not work.
Do not use Pilkington glass.
Do not use PPG glass.
Do not use Safelite glass.
Do not use ANY aftermarket glass.
Insist on Carlite glass or go elsewhere.
