Track list is ducking aids

Track list isn't the same as we always do, deal with it

Has anyone tried driving the #5 Ford? I'm finding the low speed corner handling woeful - I'm wondering if it's a tuning thing or something I need to drive around....
(I'm running the standard as-bought tune)

yeah im running that just needs to be tuned out

Any tips on where to start?
I'm finding that neutral (no brake/throttle) full steering causes oversteer in the slow corners.

I've had a fiddle with a few things, but no luck as yet.

My issue is tuning for the rising turns. Car goes all over the place. I've tried softer springs and faster rebound, harder springs, you name it. Simply can't seem to get the car tuned for those two awful corners. Anyone have any luck?

Have you tried adjusting the loud pedal?

Bah. That pedal remains stuck against the floor.

In all seriousness, yeah, I have backed off the 'loud' pedal. The car is losing all grip at the rear to the point where no matter how soft I am with the pedal, I lose the rear.

try adding rear downforce maybe and keep at small amount of throttle on. should keep the weight shifted to the rear

Added a touch downforce. Seemed to help a bit and Sonoma isn't a high speed track so I'm not too worried about losing top speed.

I swear though, I had a check of the leaderboards and the fastest V8 Supercar time is about 1:37. How the heck did someone do it hat fast?! If you guys are in the 1:37s, i'm doomed. lol

We have been competing against each other for many years now, pushing each other to go faster.
I expect the times to drop a couple more seconds come Qually.

Try no roll bars

It sounds like you're pretty lost at this point, so a base line reset might be the best place to start, and then you can see what each change does.

ARB's:

In terms of ARB's, to cure oversteer you soften the rear and stiffen the front.  Understeer is the opposite - you would stiffen the rear and soften the front.

ARB's are not the only way to cure over/understeer, but are the easiest place to start without adding more downforce.

Change your settings, and not just by a few millimeters - make a drastic change and see what happens, i.e. soften out the rear ARB by half but keep the front at baseline and make no other changes to the car...take it for a spin and note how the car changes responsiveness - is it now too understeery? Still has too much oversteer?  Start adjusting front and rear ARB from there, but only do one end at a time.

FWIW when I race my Formula Ford in the rain (that is, a real Formula Ford, not in Forza), we will remove the rear ARB altogether so that oversteer is reduced dramatically in the wet, and this is the only time we will run with no roll bars - we would never do it in the dry.  Our normal setting is reasonable stiff at the front and reasonably soft at the rear.  As we don't have wings, we have to tune a lot via the ARB's and spring preload - playing with too many other suspension parts at a racetrack is a nightmare waiting to happen, so we pretty much only ever run a baseline camber / toe, baseline ride-height etc.

Driving style (throttle and brake):

The loud pedal also plays it's part in the scheme of things, so although I was somewhat in jest with my earlier post, it still holds weight in terms of the overall outcome i.e. when you reapply the throttle and how much to start with etc. has a big part to play in corner exit oversteer.  Also the middle pedal pressure application can induce the initial bit of oversteer - especially into the two right hand corners at Sonoma you are talking about - what is your bias? Too much to the rear and the rear end will start stepping out - too high pressure and you lock up wheels and start to slide.  So maybe try there too?

Spring rate:

The two corners are off-camber, so you don't want to be softening all the springs like you said you have done as this just makes the car roll to the outside of the corner.  You need to transfer weight to the inside rear wheel to provide it with grip, thus you stiffen the front springs only, and don't touch the rear spring from base line - run with that first, then tweak (can tweak both ends, but again only work on one end at a time)

Wings and effect on weight distribution:

Wings help control weight distribution on the car, and provide drag exponentially to the speed you are going. The guideline for weight transfer in relation to over/understeer is that to help cure understeer you add weight to the rear of the vehicle / remove weight from the front, and to cure oversteer to remove weight from the rear of the vehicle / add to the front.  Simply upping the downforce at each end of the car at the same time will negate any positive effect you might see and just slow you down.

The above is what is generally accepted practice in real life - I have noticed that Forza doesn't always react as one would expect....

Too right..!!!

One will struggle to find improvements from small incrementental adjustments. Also starting to find you either have oversteer OR understeer. Finding a "balanced" setup is verrry diffucult.

Disagree. Once you're in the right area, small adjustments are very noticeable.

LolaT340,

Not going to quote as it was pretty long; however, I just wanted to say thank you! I did indeed end up resetting to default and started making adjustments as you suggested. Definite time improvements as I was in the 1:45s and have brought that down several seconds.

I have noticed that small incremental changes tend to yield 0 results. Everything you always here is "give the wing 1 turn or 2 turns" and that makes a difference. In FM6, it seems like it's "increase it in large chunks" to see any noticeable difference.

Will keep working on it. Had never raced Sonoma before joining here and surprisingly I find this track quite challenging. Where's my beloved Catalunya when I need her? hehe

Cheers,

Yes, you are right but its more that the "window" is very narrow. IMO thats what i'm finding.
