So I will not be surprised when it does eventually go. All I have is the C3 pulley, CAI, Eurocharged tune, and rear cats/resonator removed. The only cooling I have is the fan mod from the tune and the Code-3 thermostat, which is basically the stock one with 4 holes drilled through it. Takes a long time for the car to warm up during the cooler months though. And of course, the 1 colder Denso Iridium plugs, IK22. Do you remove your car seat when racing? I remove mine and take everything out of the trunk for the track. And I weigh 160 lbs. My drag radials and rims only weigh 5 lbs less than the stock ones.
I leave the seat in place as well as floor mats and other stuff. However, currently about 7lbs of interior pieces from the hatch have been removed due to a water leak. I won't replace them until I'm certain the leak is fixed.
I also have 1-step colder plugs. I weigh 180lbs, so that helps a little. As for my tires, they are 255/50/16's on lightweight CLK wheels. I doubt each wheel/tire combo weighs more than 25 lbs.
