Congrats on the new Z
OMG, new guy to manual trans
Test drove 3 other new cars before deciding on the Z and the engagement points were very similar on all. So high engagement point is not the issue as I've never had a problem with stalling my 13Z, even the up hill starts are easier than some of the other sticks I've owned. It just takes practice.
Clutch helper spring and RJM Clutch pedal will give a different feel but you still have to learn how much to coordinate the releasing of the clutch with the pressing of the gas pedal. However, easy for me to say as I've been driving sticks since I was 16 and I'm now 55
