Top work mate. And not a bad time either for a bog stock and probably not the best of tune as well as not been used to it. I assume a rotor would take abit of getting used to. Like the power band etc. I have a big soft spot for rotors now.
My cousin had a 323 with a 12a peripheral port and it ran a 13.4. He then sold it to a bloke that put it on slicks and it ran a 12.6 to become what he was led to believe the quickest N/A rotor in New Zealand.
Again top work. I wish I could take my car off the road and do something like this. Keep us informed im listening closely. Did I hear a Brap somewhere.
