Rear- end clunk sound
when its a good ol' cold morning, the rx7 likes to make this big clunk sound in the rear of the car when i disengage the clutch, but once the car is warm the sound goes away. got any ideas?

Mostly our 7's clunk when engaging the clutch.
Now you're dealing with torque unload.
Maybe loose rear sub-frame mounts?

Welcome to sucky cold performance issues with generic gear oil. Try some of this:
Transmission:
Redline MT-90
http://www.redlineoil.com/products_g...57&subcatID=18
Popular in Nissan, Toyota and Mazda manual transmissions and transaxles as well as other selected applications, this is a 75W90 GL-4 Gear Oil that’s slightly heavier than MTL. Provides excellent protection of gears and synchronizers and its balanced slipperiness provides a perfect coefficient of friction, allowing easier shifting.
Rear Differential:
Redline 75W90 NS
http://www.redlineoil.com/products_g...57&subcatID=18
This GL-5-type geal oil doesn't contain the friction modifiers for limited-slip hypoid differentials. This makes the transmission synchronizers come to equal speeds more quickly, allowing faster shifting and much easier low-temperature shifting. Can also be used in racing limited-slip differentials where weak spring design causes too much wheel spin.
