Here are three 60' times on three 15.8 runs I've had

2.308 2.286 2.271

Mods are Tanabe RM, Type-R cat, Ractive short ram intake (with custom 3" cold air extension), NGK platinum spark plugs, OBX short shifter. I also run with my interior stripped and with Miata stock tires (very soft and lots of rubber exposed) mounted on steelies at 20-25 psi.

Having the clutch should help me out too, I can already feel that it's got a lot more grab so I'll be perkier off the line
