I've added a whiteline adj 18-22mm swaybar and a generic strut bar. After awhile, I've got a stress crack (I call it a stress crack because the glass guy called it one, there's no impact point he said) across my front windshield starting from the passenger side, and my driver door doesn't close flush with the body, the light and door open light remain on. I'm going to be taking it in to Subaru to have them look at it, and obviously I'll be replacing the rear swaybar with the stock one, but could these two minor suspension upgrades cause these problems? Could I have a bent frame or anything like that? It's never been in a wreck, never hit the curb, nothing tragic has happened to it, it's only got 16,000 miles, it's a 2001 RS. Any ideas?
Thanks,

 

You can him telling you that a strut bar will crack a window into the same group as the BS excuses the dealerships use to void warranty work. The cars body would flex more without a strut bar then with one so if it was to crack from stress it would do it in stock trim. Also strut bars do very little in these cars so its likely that something hit the window and he just didn't see the impact mark. The only way to crack a windshield from body flex like he talking about (also badly enough to cause your door problems) would mean that the cars frame is bent. If its bent then you need to find out where it happened and how so you can look at an insurance claim.
