Hi, I own a very neat Typhoon. It has the standard interior, which is nice but a little drab. I can get a the leather Typhoon upgrade and then I sat in an GT-P (nice seats). Gentlemen, am I destroying the heritage and potentially the re-sale value by putting in an GT-P interior. Should I just get the leather Typhoon interior? Your thoughts please. One thing I will be doing is upgrading to 6/4 pot brembo's. I think that will satisfy the originality needs and give a nice upgrade.
