Random Thoughts - Part Deux [NO POLITICS]

[ichitaka05]

Normal way of doing Heel & Toe = Heel - Gas, Toe - Brake.
Senna way of doing Heel & Toe = Big toe - Brake, Rest of the toe - Gas
& just found other way of doing Heel & Toe = Heel - Brake, Toe - Gas.

Now.. I cannot really comprehend how that's possible. If you're properly sitting, I'm not sure how your feet can move to that position.

I can't get my leg to turn inwards to have the heel on the gas and you're on the brake

Ok I know I should let this ridiculous bickering burn out, but this I feel like commenting.

Introducing: Car C with OEM brakes. That's the one that will stop in the shortest distance.

Car A doesn't have enough friction to lock the wheels and is obviously the slowest to stop.

Car B has unnecessarily massive rotors, callipers, pads and less responsive force transfer (compressed air), needs longer time to engage fully and will need longer distance to stop than car C.

Car C with the OEM braking system will win this comparison unless your tires have so much traction that the OEM system fails to lock the wheels and engage the ABS. On a BRZ that will take some truly amazing tires.


@Tcoat has got it spot on right.

Those time, you just do Senna's Heel & Toe.

When you sit in full racing position, I'm not sure you're able to put your heel inward.

With cusco gas pedal is more easy to use senna method

I think it's a foot size thing. I have size 12.5 feet, so I can't even do toe-brake / heel-gas. I have to do left toe-brake / right toe-gas.


Oh, and for the other discussion, you can only brake as hard as your tires can hold onto the ground. No matter what else you change in the system (pads, calipers, rotor size, etc...), that will dictate your braking speed, whether you have OEM brakes or massive 16 inch rotors and 8 piston calipers. If you improve your traction (better tires, wider tires), then you will be able to brake harder and stop shorter. If you improve your traction so much that the OEM brakes can no longer engage ABS, then yes, a BBK would help you reach the performance limit of your new tires.

I dunno about you but if my knees are bent, my foot won't turn past parallel to the long axis of the car. But it'll turn 45 degree towards the passenger

Or GSpeed's Gas pedal mover... or maybe both

So you do Senna's way.

Just making sure we're in the same boat, you do normal heel & toe (heel gas, toe brake) or other... let's call it reverse heel & toe (heel brake, toe gas).

Well when car and driver tested out the kits the Brembos beat stock by like 25ft... even on the first stop let alone the subsequent ones. but you know actual expermentation versus your guys circular arguments is no comparison.

No one here said that bigger brakes aren't good for reducing overheating and brake fade. On the contrary, that's what bigger brakes are good for.

Brake fade can be a serious issue on the race track, but not when coming to a full stop from highway cruise speed.

25ft shorter. On the first stop. Maybe you missed you that part.

Let me quote from the article you linked:

Think of it this way: All brake systems, stock and aftermarket, are able to activate the ABS, so how could a stronger brake shorten a stop? Eric Dahl, a brake engineer from Brembo, put it this way: "Don't expect the brake kits to stop you sooner, but expect the 20th lap to feel like the first."

Maybe you missed that part?

And I end my debate with the undisputed expert on the subject that said exactly the same thing that I did from the very start.

Gotta love it when your debate opponent hands you the closing remark on a platter.

Yeah 25ft is like 10% shorter.. still 25ft is 25ft. That's 2 car lengths.
