Brake bias settings and advice needed.

[flying-chick]

Good day racers 🙂

I'm currently practicing Grand valley highway 1 in the huracan gt3 car.

Which as you know is an Mr car.

I have my understanding as to why I'm being faster, but currently when I set the brake bias on this car to between - 4 and minus 3 to be at the front bias I'm now getting upto 1.7 seconds faster a lap.

What else seems to be happening is the back end has now stopped sliding when I'm braking into a corner and I'm now not having any over steer issues what so ever, could someone explain this to me why ?, as I'm told this car suffers more from understeer ? So really I should be setting the brake bias to the back but for me it's the other way round ? I'm confused by this, or is this car more prone more to over steer issues over under steer ?. Or it just simply down to my style of racing as to why it seems to be the other way round for me ?


Also with setting the brake bias to the front I'm having to brake a little bit earlier to slow the car down in time before starting my trail brake.

But would I be right in thinking that the more you put more brake pressure on the front does it reduces the brake pressure on the back, hence the reason why I'm having to brake earlier ?.

And in doing so does reducing the brake pressure on the back make the car slow down not as quick making the car faster so to speak when braking ?

Thanks for any advice given

Byeeee loves 😊 ❤️.

That's not quite how it works.

The big brakes are at the front of the car for a reason (mostly suspension and mass loadings, buts it more optimal to slow a force than drag a force to slow down)

Brake balance is a driving style thing, I drive mostly front biased or neutral but it has minimal effect on my times. It's more about feel and how you drive.

Some people like to brake hard and chuck it in, others like to ride the brakes.

When people say it "aids turn in" you have to factor that in to how you drive.

Edit to your point in the quote. I brake later usually with bias to the front but only fractionally, I trade trail braking for coasting grip and exit speed, think taking the other apex the slower wider exit one vs the fast tighter one. It does depend on the car and the corner though.

Thanks, good useful points here,

Theres a couple of points you mentioned i either do or I don't sometimes, for reasons being I've broke to quickly as I've forgot to use my typical.smooth brake approach of not.to hard initially, or I've not followed the left hand track line long enough before turning in on exit as ive also forgot, this generally happens when I'm having to adapt to a new car on a new track to begin with, or having to get use to driving in different conditions with different tyres.
for instance coasting instead of trail braking, I find generally i try to do both.

For instance slowing down with engine braking and listening to the engine right at the start of the point where the engine wine starts to get slow is when I start to accelerate.as if you accelerate to quickly you cut the engine braking off.

But for me the main four points i try to address on every corner is a gentle slow smooth brake in to the corner and a gentle slow release on every corner,

Point two is the entry point and the exit point of turn out.

If my exit point are usually a bit wider as in keeping close to the left hand track side driving line before turning into the exit point right at the limit where by you can't drive forward anymore before turning in I can nail the the accelerator right at the start of the apex.

Next point is choosing the right gear to slow.down in end when to change gear down to prevent sliding and the right gear on exit point.

Next point how fast you accelerate out of each corner and into other corners, and at which point you accelerate, as if I accelerate to quickly, that's it I can forget a faster lap time



If I get all four points going my track time on grand valley highway 1 which is now set at 1.49.500 would be 148.289 in the huracan Gt3 daily race which would put me up to the top 500, even better if I use my previous optimal times uch as sector 1 I've now set a time of 33.717, and a second sector of 1.10.187 which at that stage is only 6 tenths of setting a time of 1 min 47 secs flat if i kept that pace up for sector 3.the last sector my lap time would be 1.47. 600 flat.

I may be posting this time soon 😊

Hopefully tonight or tomorrow it's long over due.

Anyhow i enjoyed this chat with you .
Sorry for waffling

Byeeee ❤️

You are way over thinking this, do laps, brake at the markers and adjust.

Lift off braking if you need more turn in, brake more or longer if you are going to fast.

That's a lot of words to brake enough that keeps you maintaining momentum.

Edit:

Watch a guide or a few replay laps, follow the ghosts and get track knowledge before worrying about the minute details of braking.

You aren't driving to a level that this sort of detail is useful. Just do laps consistently and go faster and faster. Once you hit that wall the explore this stuff but some of the fastest guys on the planet don't over analyse like this, they just feel the car and the line.

I generally do 😊 as in brake consistently at the braking points i set.


I have as question I've been wondering about, it may be something I'm not sure but do any wheel manufacturers get licenced to setting there programming and data of there wheel and pedals. to a set car given ?

You really don't get how this works, the telemetry goes outward from the game/console. The game dictates the values. That's it. The hardware has to try to cater to a huge range. That's it.

Thanks for the info 🙂
Another question do you ever set your brake bias to back for any cars or do you ever set it differently on the fly during race for different corners ?.

Byeee, ❤️

If the car needs more rotation (FF cars, general road/understeery cars) I'll put BB to the back as it's easier to get the car to pivot. Unstable MR cars I'll have it at -1 or -2 for stability. Most of the time it's on 0 as I forget completely and it's not making a massive difference to my times overall.
