Let's try to say this without upsetting the purists. 1st of all, if the car needs to stay correct. No choice but to go Borg n Beck, it's proper.

Now onto the facts. All 3 finger set ups are old technology. The pedal has the most spring pressure at the wrong time, when it's released. The least amount when the clutch is engaged. So if the disc slips you need to add more spring pressure. What happens is you get a tiny bit more on the disc but mostly on your left leg.

A diaphram style places most of it's pressure on the disc while it's clamped. Basically it goes over center when it's released making the same pressure plate that can contain alot of power, easy to disengage.

Centerforce for me.
