I don't recall that anyone on this forum has posted that they have tuned the chassis and supension of their SPF GT40 to race-level performance and exactly how they did it, or who did it. (At least in the couple of years that I've been on the forum. Anybody please correct me if I'm wrong --- and refer me to the posting.)
Be that as it may, and this may be a bit off topic, but there is an article entitled, "Chassis Tuning, Part 1" by a guy tuning the chassis and suspenion of his RCR GT40 Mark I to track-level performance in the current issue of Kit Car magazine. (I rarely pick up a magazine on kit cars, but did recently.) I know that this is a different car, but the article gives you an excellent idea in what's involved in getting a race car to handling performance way, way above what is adequate for the street. The article goes into engineering-level discussions of suspension geometrics, springs rates, formulas, etc. and the theory of chassis design and tuning way more than you probably care to know, but does provide a good indication of the knowledge, equipment and instrumentation involved to bring a car up to, allegedly, racing-level handling.
(Whether I get a SPF GT40 or not is contingent on being able to have the car's handling performance tuned to track-level, and I am unawares of any constructors of the car that have the knowledge and equipment to do such. (Some can't put the car together well enough to get the new owner home.) Dennis Olthoff may be an exception, but nobody has reported so. The video clips of him tracking his car at a couple of tracks linked to from this forum a few months ago don't indicate that his own item is tuned to anywhere near race-performance handling.)
