[QUOTE="Tob, post: 16307854, member: 83412"] I knew you'd go this route. No need to overcomplicate. Rubber is the big difference between the two. And most anyone that tracks [i]any [/i]car, uses an appropriate tire. And since the CFTP cars are as good as unobtainable, you are going to see plenty of Base car owners that track change to a more appropriate tire. Simple. Regarding a comparison - never say never. A "real professional test" will likely be done by people who will want to know the answer to the exact same question. A jack and a lug wrench are all that is needed here. No waste in sight in this regard. Data point, related or not (so a potential "waste of keyboard strokes as some would call it). At the IMSA finale at Road Atlanta I had some great discussion with Dean Martin and Nate Stacy. I asked if they could pin down an improvement in lap times to the mere switch from Continentals to Michelins. Both Nate at Dean agreed that at Road Atlanta there was a solid 3 second improvement. This led to my next question, and I wrongly assumed that this improvement came at the expense of how long it took before the tires were wiped out. Again, both said the same thing - the Michelins last [i]longer[/i] too. Michelin seems to be doing a great job of improving their street tire compounds as a direct result of testing to the limit in various race environments. Same engine, transmission, driveshaft, differential, half shafts, and brakes. I'd guess that Ford tunes the Mag dampers differently between the CFTP and Base cars due to the weight of the wheel/tire package, spring rates (and I've seen nothing to indicate they are different), the friction coefficient of the tires, and the implied intended usage of the car itself. So again, the biggest variable is Ford's decision to use different tires, one with a rather large advantage at the track over the other. If the Base car is allowed to run on equal footing, the CFTP advantage quickly evaporates. [/QUOTE]
