All of our cars are currently prepared to ITS specs. I found that to be the overall best balance of cost, performance, reliability and fun. In ITS spec we are just enough faster than the good Spec Miata's that we don't tend to interfere with their races when we are together. The ITS car can also run in PCA 4 on the same day/weekend to increase potential track time. ITS is also recognized in ICSCC, so you can run ITS, RS, SP, EIP, or eventually 944 Cup class there.
You can contact me directly with any prep questions at
greg@fordahlmotorsports.com or call at (425) 644-6020. I think the 944 Spec preparation allowances are just a little off in a couple of key areas like reliability mods and being forced to run the truly awful Toyo 888's. A Spec 944 will place you right in the middle of the Miata grid....good luck with that! Greg F
