I got the HPI racing clutch a few months ago, on the instructions it has 3 different ways to installing it, by cutting it and using different holes.
For the people that have it, what setup are you using???

1- engage at low RPM for smooth acceleration
2- engage at higher RPM for more bottom end
3- engage at higher RPM for even more bottom end

What does "more bottom end" means??? More top speed???? More torque????

Most of my driving is parking lot.

Thanks
