So with a few minor bolt on's the car is in the 11's on 255 street rubber. Not uncommon for a 03 but one of the track rules is that you need a SFI approved harmonic Damper on anything running under the 11.99 mark. Are all SFI dampers created equal I would not think so, so looking to see what you guy's think. I don't want something like a Damper to end my fun at the track for the day when I could be having fun.
