I had heard of this problem happening in 964's and very early 993's due to running larger rims (and therefore lower profile tires) instead of the stock setup. My understanding is that this is due to the change in window adhesive used during that period. I think mid way through '95 Porsche changed back to an earlier approach which curred the problem. My question is if this is beginning to happen to the front windscreen is such delamination concerning and how expense is the fix (I assume the windows need to be resealed)? Thanks...
