Like most I've opted for the Tremec TKO box.
With this I have a choice of torque capabilities and 5th gear ratio.To help decide which one to go for I put each option into excel and a little motormath program I found on the internet.
With the wheel and tyres sizes from GD and the 3.07 diff I have I was able to figure out the following results.
So I settled on the TKO 600 with the 0.82 5th, a chat with Andy at GD confirmed my choice as a good one. I should be able to cruise nicely but be in a good position on the torque curve should I wish to get things moving without constantly having to mash the gears.I will be sourcing the complete kit, minus flywheel and bolts, from Repower, spoke to them and found out that the only draw back is that prices on Tremec missions is increasing due to raw material price rises. Looks like I've got to budget a bit more now, never mind.
One thing I have decided is I must have a smooth aluminium shift knob, my Type R has one and it feels really nice in the palm of you hand, strange but true!
