I just got an email back from Anthony Chesire at FFCorse in UK. They Prep and Run F430 Challenge Cars in this Spec and Cup Spec which includes Large Rear wing, Front Spoiler and Suspension Setup Changes. He stated that the Cup Spec is 2 - 3 Seconds a lap faster than a standard F430C. He also stated that in their GT Cup series in the UK last year, that a 997 GT3 06/07 Vs a F430C Cup Spec are very similar. Last year out of 14 Races the 997 GT3 won 7 Races and the F430C Cup won 7 Races He also mentioned that the F430 Cup Spec was designed to produce comparatie times for these vehicles. For those that are interested the Cup Spec cost 20,950GBP not including fitment.
