I've had it with this tuning lark...(Forza)

[ih8thisname]

Somebody HELP!

The culprit is an E30 M3 - in my eyes the pinnacle of Bavarian rocket powered madness!

My plan is/was to turn this into a Mini Cooper eating B700 animal, but sadly at the moment this seems to be a long, LONG way off..

I've tried numerous online suspension calculators to give me a base to play on, but to be honest I can't help but feel this is just like cheating. So, PH collective, I'm here for your help.

The main problem I'm trying to overcome Power-Oversteer on the exits without sacrificing turn-in. I know this is more down to driving style, but I have tried all different techniques.. Going gentler on the throttle, feathering the throttle, heel-toeing, even coasting round the corner gets the fking arse out!

Don't get me wrong, great fun! But when racing this isn't really all that helpful..
Here's what I've tried already:-
Decreased the front toe and Increased the back.
Set the Anti-roll bars/Springs etc stiffer in the front and the back
Haven't been sure what to do about bump/dampening, but having a little more front bump (fnarr) than the rear has proved to help a bit..
Camber..Don't know where to start with this other than giving it some extra negative.

I'm not really asking for a set-up, It's something I would like to learn to do for myself.

I can feel it though, this car has sooooo much potential, but at the moment it is quite frankly, an absolute dog.

Hmm this is a difficult one Nick.

As far as I can gather, the M3's on this game all oversteer like a bh regardless.

Have you tried the full aero pack and max downforce on the back?

[The_Jackal]

From what I have read on the forums, the E30 M3 aint much cop in terms of competing against other cars (at least if you want to go round corners that is).
I think it is only in the game as more of a nostalgic nod to the past.
I fear you may be trying to polish a turd.....

Hmmmm, I haven't!

The only adjustable aero mod is the fin on the boot spoiler IIRC, will have a look later though.

I tried copying the corker of a setup from that green mini...

That turned out to be, well... Interesting...

you need to soften the rear or stiffen the front or both... but as you said there will be a price to pay with turn-in understeer. try turning in on the brakes to negate this.

This is good advice ^^

Softening the rear suspension a little may also help.

Other things you can try include making sure the rear ride height is not more than the front (this is called rake). Reducing this will reduce lateral weight transfer.

I'm not familiar with Forza, but if possible, have a look at the tyre temps across the rear after a few laps. Try to get the temps reasonably level across the tread, first get the outer temps similar by adjusting camber, (increase camber if inner temps higher then outer and vice versa). Then get the middle temps the same as the outer ones by increasing the tyre pressure if the temp is too low and vice versa.

If the rear toe is quite low, try increasing it. It must be a positive value if you have oversteer problems.

Again I don't know if it's possible in Forza but if the differential is adjustable, change the power setting so that the wheels aren't locked together so much. This may cause the inside rear to spin on corner exit but the car may be more stable.

Thinking about it, the first change I would try would be the differential.

All of the above I have learned from sims, so I could be wrong, don't try this for real

HTH

[Nobody You Know]

Hmmm from real life experience I would say stiffen the front bar and knock a couple of clicks of low speed bump off the rear dampers. Don't go too high on negative camber or your inside wheel will spin up easier and with the LSD this will cause the outside wheel to spin up creating oversteer.

Also try reducing the front caster angle to avoid unloading the inside rear wheel.

nick i'll look at my one and i will see what results i will get from it! what track r u having prob with the car?. alan

As has been said...

• Stiffen it
• Setup the Slip Diff

I found that car a bit of a pig, fun as it was!

All the BMWs actually seem to be loads of fun with a Steering Wheel but not so much for actual lap times.

Which is odd 'coz I thought the '330d' was the fastest car ever!!

Only in the "mapped" mod.

Stiffness - As said earlier, keep your stiffer anti-roll and springs at the front, but soften them (relatively) at the rear. You're on the right tracks with softer bump at the rear vs. front.

Camber - not sure how negative you have it already, but look at real DTM cars...they have a heck of a lot of neg camber at the rear. Experiment with going extreme on that.

Thanks for all the advice guys, some invaluable stuff there SlipStream!

I'll give it a go later. Thanks again!

I was thinking earlier that with all the experts on here, maybe they should offer there 'tuning' services. ie you tell them the car and budget/class, they tell you what parts to buy, you then gift it to them, they tune it and send it back. You can then agree a 'tuning' fee in the form of another car for them to sell

[The_Jackal]

The official forums are full of "Tuning Shops" complete with catalogues.
In the most part these cars are fairly good starting points if you are not a tuning genius. However different cars are tuned for different styles of drivers. Dont expect a tuned car to automatically make you faster. You may have to buy a few until you find one that suits you.
Also there is no substitute for knowing a track like the back of your hand and just running lap after lap after lap.
