Im trying to justify cost, yellow saved half a metre! Your "science" isnt helping.

Finally sold. To a friend of a friend.

Got the opportunity today to test the brakes, and coding, in Tauranga today... f**kknuckle in a van pulled out in front of me at 80kmh, I slammed on brakes at full noise, got ABS pulsing and the skippy lockup feeling.... full emergency stop. Missed the asshat by about half a metre, probably half a metre that I didnt have before to be fair. So they've probably paid for themselves

e-diff, but it was only on lcis (which that isnt), and is sh*t. Just works like traction control by braking spinning wheel, sending torque to the other.

I was totally in the camp of BBK wont stop you quicker previous to these posts, but did about 20m of reading on the internet and now am expert, and that might actually be wrong as its not as simple as locking the wheel. Maximum friction between tyre and road is right at the point before lockup obviously. If BBK hooked up with ABS can control the wheel speed more accurately, through more braking torque and clamping force, then the wheel/tyre could be held in the sweet spot of maximum friction better... which would reduce braking distance. Should have done some testing before hand, stock vs BBK vs BBK with coding, would be curious if there was any difference initial stop distances.

Don’t worry, the massive simplification of braking systems down to its only tyres isn’t really science. Back in the old days of single piston sliding calipers and mechanical / hydraulically actuated ABS systems the tyres and driver feel were big factors. In the modern world of computer controlled and modulated braking systems there is a lot more to it. As you have correctly pointed out having a brake system correctly calibrated and controlled makes a difference. A similar difference between an un-trained driver stomping on the pedal or a pro modulating braking pressure.

Head into the local dealer in the morning

Got codes 38 and 39, and 3 unidentified...... if you have no luck, let me know asap as will be going out to stored cars over the weekend and can go through them too. Worst case if you're stuck and need it done straight away, use a double hex socket, smash it over the outside. Just make sure it's a tight fit (can check what size I've used before, it's an imperial one). Has worked for me every time.

Bigger brakes don't help you stop shorter in a one-off situation, stopping distance is purely related to the friction between the tyre and the road. If your brakes can overcome that friction (lock the wheel), which all passenger cars can do easily, then brake size is not a factor. A BBK is for more effective cooling and more consistent stopping. After 5-10 quick, hard (ABS) stops a quality BBK should perform noticeably better than standard sized brakes. Because of the initial clamping force and lower pedal effort a BBK may feel 'stronger' (shorter stopping distance) but that's just a physiological trick. Some good (and some not-so-good) explanations here: https://www.quora.com/Will-putting-bigger-brake-rotors-and-pads-on-your-car-make-the-car-stop-faster-or-not-necessarily.

Getting good at doing these, 3 hours.

@balancerider undoubtedly! But... fun/performance/resale... it depends on ones priorities.

You're really living the dream aren't you... I shouldn't speak too soon... I've got 2 passenger seats doing the twist on my e39's... plus a LSD diff on the Monaro with misaligned internal splines after taking an axle out and inadvertently rotating the other axle... But yes.. all good fun.. and each one a learning experience... as I repeat to myself constantly...

Do as MacGyver would... Drive up on a kerb, take the sideskirt off with a 10mm and 3 bolts, not hard.. ?
