sorry to tell ya this, but pretty much every integra does that, ahha, you can check your tai lights , the seal might be deteriorated and letting water pass, you might also have a hole where the quarter panel meets the rear piece, its welded and also puttied, but mine had a whole and thats where alot of water came through at.......some people have had a problem with there water tube or something clogging up, you might want to do some research on that....http://www.team-integra.net/sections...?ArticleID=546
