Flat shifting
What is it? I've seen the term used before but never knew what it meant!

used to have a box set up, that allowed it without hitting the rev limiter,
Keep the accelerator pedel to the floor, engage the clutch, and the revs would hold at where they were, say 5000rpm, change gear and keep going.
Stops the revs dropping off through gear changes, and stresses everything out alot more

clutch in - shift to neutral - clutch out - clutch in - shift to next gear - clutch out
double clutch and heel and toe -

Can't see that it's quicker, essential for old cars with 'crash box' (no syncromesh)
Also on a proper flat-shift set up there will be an ignition cut so you get a back fire BANG!! during gear changes. Can be actuated by clutch switch or load cell/micro switch gubbins on gear lever.

Most mk2 rally cars people are fitting flat shift. It allows the gearchange to be made without lifting of the throttle usually worked from a strain guage on the gearlever which connected to an ecu. It cuts spark/fuel to take the load of the gearbox and saves driver error of not timing the throttle lift right and damaging the gearbox

I run flat shifting on the FFD 7 Speed box in my Escort, it has to be one of the best mods out there for track.
You just keep the foot planted and pull that leaver
I run the fuel cut only
This is what it sounds like

Double clutching is slower but needed on older boxes with no synchro mesh. Drove an old (see stone age) Bedford horse box that needed double clutching.
Heel and toe is a very useful technique I even do it in the company pool cars

So combat 'pad knock back' - when he goes over kerbs and under heavy cornering forces the pistons can get pushed back into the caliper by the disc rotor, so when he brakes he will have a long pedal (excess travel) by tapping it with the left foot on the straight before a braking zone, his brakes will be 100% when he needs them.
