Hehe, I thought rather than stuff around testing I'd get a few responses to try... I have my own ideas of course
I don't want less grip, I want less front end grip when I smash over the huge chicane kerbs, so it just understeers out of it rather than spinning.
Tweaker - fo8 on fern black. I know too much power locking will cause issues too, not going any lower than 40% that it's currently at, though it would make the bumps easier. So far I've found absorbent works better most of the time, but occasionally it just seems to get caught the wrong way... I thought a lower and stiffer front end would help, but maybe I should have tried lower and stiffer rear instead.
It's fun to post isn't it.
How to reduce front end grip over bumps?
Anyone know the best way to reduce front end traction over large bumps, more so than rear end? Without substantially affecting the balance of the car otherwise?
Take the fox for a drive on westhill with moderate pressures, then crank them up and see how much faster you go.
No you don't. There are a number of cars where signifigantly quicker times could be achieved if there were no upper limit to tyre pressure.
nice. hopefully someone fixes the useless ffb and then I might play the game...
err, got a replay? 'Locked' isn't torque dependent, it's locked. If LFS behaved as you described it would be rather broken...

Changing tyre pressure in large amounts is hardly a step I would take in the fine tuning stages of vehicle setup. Will throw temperature and acceleration out the door.
Camber on the front was already at a level optimum for low speed grip and manageable temp wise. reducing it further would reduce outright corner speed and not make full use of the tyres. Adding camber to the rear would mean the insides get too hot. Adding pressure to compensate for this would change the low speed balance again, and reduce traction out of the low speed corners.
Your examples other than camber are wrong, in my experience. Lowering tyre pressure down a few psi doesn't give you more low speed grip and less high speed. Tyre pressure is also critical for temperature and speed. There is a point where you can adjust camber for either better low or better high speed, but if you set it for high speed you destroy tyres much quicker. Throwing differentials, anti-roll, and and toe settings in is quite laughable, all have a similar effect at all speeds.
I found myself in a situation at Aston North, with the fo8, where I was trying to tweak the balance for the loosest (thus fastest, and best cornering) setup I could handle. I had my tyres set at a level where they worked well for the low speed sections and didn't overheat. 1 click of downforce either way was a massive change to vehicle handling. High speed cornering a touch loose, low speed cornering not loose enough. What would you suggest? half or a quarter degree of downforce on the rear, and a little more rear anti roll, would have been the perfect, simple, logical solution.
People can still adjust it in 1 degree increments if they want to! Having smaller changes possible doesn't suddenly make it harder to work out the effect of a change.

Tweaker, you entirely miss the point. I don't know why you are at such pains to do so. Downforce affects vehicles in a specific way. Other settings can be combined to achieve a very similar feel to a change in downforce, but this is less accurate, more prone to affecting other areas unintentionally, and entirely unnecessary. Can you name any other areas of adjustment that affect high speed turning more than low speed?
4998... fun, but could be better designed I reckon
Yes... sometimes good results take more work, it's a frustrating world isn't it...
I find 'exercise' too dull. So I rockclimb and dirtbike. Keeps my body healthy, and also tends to trivialise a few of lifes more petty concerns...
Does constantly fulfilling short term desires necessarily equate to best long term happyness? Scientific studies of Buddhist monks say no
The huge 'blue flag' isn't enough? Fair point though.
yes. cars should only go orange when they are a lap down, turning orange on the same lap is pointless, imho.
I generally find clutch packs best in rwd's, with power side locking from 20-50% in high power cars and more in the low power things. Brake side locking depends on the track, anywhere from 40-80% usually.
Locked difs require too much compromise in the set imho. They understeer on entry at low speed and oversteer at high speed - generally the opposite of what I'd want. I see no improvement in corner exit speed with a locker - you have to reduce throttle instead of keeping it open and bleeding off any excess power through the inside wheel.
Even in the fwd's I've been moving to clutch pack lately - I find a locker provides too much variation in turning between power off and power on. Power off and they understeer like mad, power on and they oversteer like mad. Pretty much the opposite of 'normal' fwd behaviour. 80% power side on the clutch pack means I can pump the rear tyres up, set the suspension and steering up so I have fast, controllable turn in without throttle, and getting on the throttle just tightens the line a little bit, rather than madly wagging the tail as with a locker.

seems to forget passwords for favourites every so often - haven't tracked down a repeatable behaviour for it though 
yes - consistency within the different setup options. Either aero should have more adjustability or the others should have less
damned reposts
Even if the current degree of adjustment is 'accurate' it seems a little at odds with the rest of the setup features huge adjustability.
Tweaker - just because you do not understand the benefit in something doesn't mean that others would not. This suggestion takes nothing away from the ability to add as much downforce as you want, making the difference noticeable. I have been working on a set for the fo8 at aston north. One click of downforce either way makes a huge difference - either it doesn't turn enough or it turns too much. I can of course adjust this with the highly adjustable suspension settings, but they affect low and high speed corners equally, which is not ideal. I have confidence I'll be able to find the right combination eventually, but it seems a pointless complexity to the process.

Decimal point for aero adjustment
Adjustment isn't fine enough at the moment. I assume the adjustment mechanisms in reality have free range of movement within their total range??
what would be an interesting format Glenn?
