I'm considering building a 944 turbo to race in PCA class F and SCCA ITE. The GCR doesn't specifically cover ITE, but it is implied that IT rules govern the ITE class. My question is that the IT rules specify no tire width greater than 7". The stock rims on the car are greater than 7". Can I not run the factory size wheels in ITE? Do I have to run narrower rims?
TIA,
Scott
