Do you adjust LSD or Brake Balance to solve corner entrance oversteer?

Soo...

I'm driving with that Elise 111R, almost stock, in the Expert Challenge Race from 08-06. I bought the customisable LSD, rest is stock.

As we all know the Elise is tail happy when approaching a corner.
First thing I did was adjust brake balance from 5-5 to 5-2.
That solved the problem, laptimes were a nice 53:500 and was easy win.
Then I decided to set brake balance back to 5-5, and adjust LSD under braking (normally 20) to 45.
That also solved the problem, laptimes again 53:500

So I was wondering... whats best?
What would you adjust and why? Brake balance, LSD or a combination of both?
 
I set the brake balance, but used the oversteer to help me win this. If you have installed the rear wing, that'd help too.
 
I was just about to post a thread on how to fix the entrance oversteer you just mentioned while I was doing the Tsukuba 9H. I ended up solving it mid-race by adjusting the brake balance. I don't know whether or not the LSD would fix it, but the brake balance sure did.
 
This is probably a question better suited for the Seasonals forum, but here is a thread with ten or so 111R tunes. I used one of them to win that race.

Actually, as this is about tuning, the Tuning section would've ben more apt. Especially as I've seen threads in there that detail brake and LSD settings that would answer the OP's question.

Just copying someone else's tune, you won't learn anything, and next time the problem arises with another car you'll be just a stuck as you are now. By adjusting the relevant parts with the OP's setup in place he'll be able to see and feel the affects of the changes, helping him to understand and apply any knowledge to other cars.

The brakes and the braking sensitivity in the LSD do two different things and are applicable to two different sections of 'corner' entry.

Adjusting the brakes will affect what happens when the brake is being used, as soon as you lift off the brake, the braking sensitivity on the LSD kicks in.

So depending on whether the car is oversteering when you brake or after you've lifted off the brake will determine what exactly you need to change.

With regards to what you have done, you are correct:

Oversteer when braking - usually you'll have to have the front brakes higher than the rear sometimes by 1 / 2 / or 3+ (depending how bad the oversteer is).

However, if your brakes are currently set at something other than default or level, then returning them to default might be worth trying and then changing them 1 click at a time to get the desired affect.

Oversteer once you've released the brake - usually adjusting the braking sensitivty on the LSD to a higher amount will help here. However, this setting also applies to lift off acceleration aswell (as brakes) so you need to be careful not to overdo it and subesequently make the car understeer when you're lifting off the throttle aswell.

Sometimes other factors can be utilised to help the rear end be stable - i.e. camber and toe figures, but the brakes and LSD are a good place to start.

If you running minimal camber, say under 1.0, you could push this up to anywhere between 1.5-2.0. If your running negative toe, then maybe change this to a minmal + toe figure BUT too much + toe can result in understeer at the front.

Also note - having a rear ride height lower than the front ride height will also induce 'lift off' oversteer, both after braking and under acceleration.

Good luck :D

I was only saying the Seasonal forum because there were sufficient sources to answer his question there. Either would have worked, I suppose. I don't understand tuning, so that thread was gold when I found it :).

If you don't understand tuning, you need to scour the tuning section - there's some excellent threads in there that will tell you everything you'll ever need to know. In fact, I'd go one further, there's threads in the Tuning section that are worth their weight in gold when it comes to setting cars up.

Plus, at the end of the day, we're talking tuning and that is the tuning section :D

You need to understand tuning better, start with these - they're superb:

Anti roll bars

https://www.gtplanet.net/forum/showthread.php?t=198591&page=2

LSD's

https://www.gtplanet.net/forum/showthread.php?t=203009

These two things are great starting points and can have a huge affect on a cars handling. But also, what else is said, especially in the SRB thread (about the relationship between springs, dampers and roll bars) is very important.

The seasonal events don't count. Offline setups don't work online, whereas, online setups work offline as well as they do online.

Forget, offline setups, you'll run into a brick wall when you go online, deal with work works online only, and in the game - not real life.
 
Thanks :). Hope I could help somewhat, OP!
 
No my question was litterally: do YOU correct corner entrance oversteer with LSD or Brake Balance :|

Als I mentioned int he OP I already know how to solve it, I was just curious how various people would solve it.

The way you worded the thread title didn't make that 100% clear.

Why oh why couldn't you have said, I know how to do this, but I was wondering what everyone else does in this situation....

Most people who come on to the Q&A section do it because they need an answer, people who want opinions generally do 'polls', or at least make it clear they already know the answer and are after an opinion.

Your thread title and op seemed to suggest that you were asking if what you were doing was corrrect, and you wanted confirmation of this and the reasons behind it.

Besides, you don't seem to 'know', as mentioned in my post, the diff and the brakes affect oversteer at different times. One is DURING braking, the other is AFTER braking, this is a big difference - and you didn't seem to be making that clear.

Please be more accurate when asking something, some people on here like to help and it's not nice to be thinking your helping, when in fact you're wasting your time because the OP can't word their request properly, or put it in the right place.

I'll refrain from saying what I really think....
 
I would adjust brake balance for corner entrance...LSD for corner exit.
 
Relax. If you and Cam want to be admins so badly just apply for the job.. sheesh....

I'll relax when :dunce: stop wasting the time of people trying to help (those who genuinely need help), think they know something (when they don't) and then throw the help they've received back in the face of the people trying to help them.

It has nothing to do with wanting to be a mod or admin staff in any way, it has everything to do with people who don't respect those who are trying to help them and show no gratitiude in return.

Of course - you are so 'right' and we are oh sooo wrong aren't we, that's why you don't know the difference between brakes and a LSD and your use of the English language is oh so clear and precise.

:rolleyes:

Would you like some binoculars so you can see the serfs when sitting on that throne of yours?

calm down OP^^
Highlandor offered an explanation, provided help, gave links and stated a reminder about actual posting guidelines (which should be kinda standard).

IMHO there is no valid point in offense against him.
Cheers

I fix it with brake balance as I think that braking sensitivity increases understeer so I always leave it at 5 unless the brake balance can't fix my problem.
 
I usually start with brake balance (6/3 or 6/4 for the Elise), then rear toe (33 for the Elise) then the LSD. Like most others said I usually use the LSD for corner exit, but with the Elise I will use any help I can get. There are a couple of other cars with nasty lift throttle oversteer and usually the combination of brake balance and toe fixes it. I have only recently started to experiment more with the LSD for controlling the entry into a corner, so maybe in the future that will change.
