You must be one seriously lanky c**t if you *really* don't fit in a Golf2 GTI stock seat. Either that, or you've got seriously stumpy legs. 6' 3" doesn't sound right not to fit in. Do you have really big hair or something?
With the Scirocco seats in my Golf they aren't on the lowest height setting and Chuff and I were tearing around Combe with helmets on without walloping them on the roof lining.
Your driver's seat DOES height adjust, doesn't it?
