Reply to "Need help on which route to go"

Eric, after I hit the "post" button the other day, I see you had already responded to George, so I didn't have as much background, then as now, on your intentions. So yes, my comments were from the perspective that "it's only original once", and you are fortunate to be not far removed from that condition. There may be some resale value premium to be found in a high level of originality, certainly in the limited numbers of genuine GTS cars around. In any case, I think George would agree, there is a good bit of performance and reliability improvement to be gained with relatively simple optimization of more - or - less stock parts. Likewise, reductions of weight where possible, with better tires & brakes, can add noticeably to the overall performance.
