I think that's about it.
Nice. We both are lucky so far with the stock Diff. I've had about 200 runs at the track the last 3 years and am still amazed how well my rear diff is holding up. 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.
