Check out www.nationalroadrally.com go to Sunday Autocross...My stock Z has Kumho tires and 5Zigen ProN1 rims..no other modifications...and I ran my best time of 48.049..came in 20th but look at the cars ahead of me... a 2003 Corvett Z06 turned a 47.62 ...a $140,000+ 2002 Porsche 996 Twin Turbo...47.445....at 61 years old...my reflexes are a tad slower than those younger guys..but next week I'll let my son drive and see how he does....he has a 944TT street prepaired...but he didn't run in this last event....Love my Z...Joe Z
PS anyone have any suggestions on how to get a little more out of my Z...
