High-power FF cars: how do you make them turn?

[Bluez_Freak]

I have 2 Peugeots (106 S16 and 207 GTi) both of which are tuned to death (I think about 280 and 380 hp respectively) but they problem now is they won't turn anymorein the corners.

What do I need to do to cure this awful power understeer??

 

[66'Roadster]

I get the same problem with my maxed out Focus ST. Goes like stink but wont tight turn

Buy a LSD and mess with the settings...
That will help a lot 👍
Also, try the suspension, normaly FF cars have harder suspension settings at the back

LSD is less critical for FF as I have understood but I will try.

Regarding suspension probably even harder back settings are needed to make it more oversteery??

Or maybe 1 grade softer tyres in the front?

I don't know how long you been driving,but if you slow down and learn to drive these cars that you speak of,then you'll know how fast you can go,it seems like everybody wants to go fast all the time.At some point you have to slow down to turn the corner!!

Similarly powered (250hp and above) RWD+AWD simply turn much much easier than FWD equivalents.

That's my problem and BTW I know how to drive.

I wasn't saying that you didn't know how to drive,the cars in the game are almost realistic as they come,but lets face it if you have the right settings on the car,it will turn if you slow down on the corners.I had the same problem until i started to learn the car that i was driving,when i could push it hard,and when it was time to break before a corner,and know i have a lot more fun playing this game!!!!

No you dont and you admitted it. FF cars heavily rely on the LSD to keep the power down on the road. Also could it be that all the weight is nearly all in the front perhaps? Dont drive it like a rwd car.

LSD is critical, depending on how much hoserpower the car has. Both the examples you gave are powerfull, so you will need it.
One simple way of confirming this, is acelerate hard out of a corner (from the apex) with a FF car and look at the tire graph. One of the wheels will spin, the graph will turn red, and you will see lots of tire smoke.
Front aero is helpfull either.

 

[Temetias.]

Positive toe @ front to increase grip and negative toe @ back to decrease it. But ff car with too much torque is impossible to turn because of the wheelspin. That's why Hondas are the best FF cars in the world: they have no torque.

But you shouldn't be driving a FF car the same as a FR or AWD car, they require different techniques even when dialed in perfectly for your liking.


Definitely adjust the LSD, it should help a lot.

In the tuning menu, in each category, there are little yellow question marks. Click on them. Read. Learn.

LSD becomes more critical on FF as you add power. I start front drive cars LSD in this range.

Initial 8 to 12
Acceleration 12 to 18
Braking 8 to 15

LSD still helpful for FF, just lower settings than other drive trains.

That's actually very, very low for a FWD car. Small, light, low-power FWDs will probably like it as they don't have much issue with traction, but when you get into the crazy bastards (300-400hp).... I start at 20 and increase from there. My C30 was easier to drive with 7/22/5 on the diff but not quite as fast as it is with 7/50/30. Then again, I tune my FWDs completely backwards and get on-throttle oversteer in some cases.

So to cure power-on understeer... Stiffen the front springs, soften rear springs, reduce front extension, decrease front anti-roll, increase rear anti-roll.

My srt4 has 600hp and that thing is crazy

Well i did make a post in the Tuning forum about setting up an LSD but it kinda disappeared!

Stiffer Front suspension \ Softer rear suspension

Rates : 9.6 \ 3.9
Ext : 7 \ 5
Comp : 5 \ 4
Anti-Roll : 2 \ 3 or 3 \ 4

Brake Balance (Your Preference): 5 \ 6

So i bought the fulky customisable suspension for my 435 bhp focus ST, gone thru the settings. Stiffening means reducing ride height yea? (Set to- 3, rear to+ 2)
anti roll set to rear-6.. front 2 (default is 4,4)
Extension reducd from 4 to 2.
What about dampers compression(4 default again)?
I should have become a mechanic- i find this tinkering fascinating!

Actually, you'd want toe out on all four corners.

Yep i really dont know! Only car Ive driven for real is a rover 100 on my driving lessons whoch i was unable to complete. I came to cars and motoring late in life- now I find it all fascinating and want to learn more.

I hope that this don't get me in trouble..

In this guide you will find the basic knowledge about what can be tuned in a car. it's very summarised but you will be able to start tuning your cars

Ah thanks! Im finding tinkering wth parameters on an LSD makes a big difference!

In this case it's really about handling the power, not the actual cornering grip. Positive front toe increases straight-line stability (decreases wheelspin) in most cases. Usually helps high power FF cars to turn.

Normally yes, toe out means better cornering and reduced turn-in.

 

[stevo_mahony]

Simple way to look at it is a ff cars front wheels are trying to do 2 jobs at once when they would much rather do one. So if you turn your lsd down it will let the inside wheel pull/spin as the outer wheel holds grip and turns you around the corner. Or you could baby it threw the turns, but where's the fun in that?

Actually loosening the diff in a FWD just makes it slower and understeer more with less throttle. I've found that unless it's a very small and fairly low power car you need at least 30 accel to keep the inside from lighting up and I've seen an accel value in the high 50s make the car harder to drive but faster around track.
