5MT has a push clutch, 6MT has a pull.
There are however exceptions to the rule, because nothing is easy.
Just to correct Peter - There is no 5MT 2.5L GT, only the 5MT 2.0 GT and 6MT 2.5 GT Spec B.
HardwareBoB states 240mm

The 2.5 litre turbo models with 6MT have a 10mm smaller diameter clutch disc. The H6 is 10mm larger.

A number of the ebay sellers are promoting the 230mm HD kit for the EZ30 H6 units?
Buyer Beware.
Cheers!
BillyCorgi states 230mm
If i was to buy the 230mm it will be the FJK-8294HD (heavy duty)
if i was to buy the 240mm it will be the FJK-8658HD (heavy duty)
can someone give me definitive answer and a review on these HD clutches? is the pedal feel going to really heavy?
