There's a point with car setup that I haven't fully comprehended so far. So maybe you can help me on this - well you definitely can.

I have always trouble using a predefined setup for a RWD, the cars are very unstable accelerating out of a turn. So I understand that I am a bit to aggressive on the throttle, but still I cannot control this good enough so far.

So what I found out ist that when I set the rear antiroll to almost full strength (leaving the front as it is) then it's quite easy to control this. But there is no rose without a thorn, and therefore this has to have a drawback, which I guess is that the car has problems in turns that are not perfectly plain. So my plan is to slowly reduce the setting to normal values as I get better in car handling.

Reading the manual it is far from logical to me that this works, because antiroll should have an effect in the turn itself, not when leaving it. So here are my questions:

• Why does this work?
  
• What are the downsides of this setup?
  
• What other (better) alternatives are there?
  
• Is the mentioned problem really connected to being to aggressive on the throttle?
  

Thanks a lot in advance.

Acceleration out of a turn is a transient thing, meaning dampers have more of an effect than the antiroll bars (although these have an effect on the whole cornering phase too), also there's the % lock of the diff, the rear toe setting, relative cambers front and rear, and ofcourse, your driving. You being a "new guy", you can hardly be surprised if the rear end of a FZR/XRR/FO8 gets away from you.. so just find a decent setup (setupgrid.net) and drive that until you can get within half a sec of some respectable race-pace. Reason for this is that your skills and objectivity are not yet on a level which allows you to make distinctions between what is a car/setup fault and what is your "driver" error. Even some very fast people will rather poke around at the setup insted of adjusting their driving technique to reach a goal, a real driver should be able to do both.

If its using the clutch pack, try dropping the power lock below 60%, should help a lot. (i know some fast guys in the fox only use about 55% lock)

Sounds about right. I ran in OWRL Div B earlier this year in the FOX and was up at the sharp end with MaRDoX and vincper with around 50-55% power-side lock on the diff, IIRC.

Funnily enough, I'd gotten so in-tune with the open-wheel cars that season that I couldn't drive anything else from then on. Once I got back into the FO8 from being in the FOX, though, I was able to make it turn like never before. The FOX kinda opened my eyes with regard to how a car should be able to turn, whereas most of my previous FO8 sets were a bit on the understeery side to make the power more controllable.

O.K. I checked it once more and the problem seems to be, that the car is oversteering in mid-turn. This would explain why setting the rear-roll-bar to very hard helps. But as this is not a "normal" setup, there has to be something wrong with my driving.

What is it? What should I try to get rid of this problem?

A stiff rear anti-roll bar will tend to induce oversteer. Likewise, so will a soft front anti-roll bar. Vice versa for understeer.

It might help if you posted your set.

O.K. I will post a setup this evening. But the point is, that I have the problem with all the normal setups.

So when I download one, I just cannot get the car around a turn until I change exactly one detail, that is stiffen the rear antiroll-bar. Suddenly everything works fine. So imagine every setup for a RWD with a rear antiroll-bar set to a high value (90 for FBM for example).

Which brings us back to your driving. You are probably doing what every nab does at the begining, you approach a corner then brake, get off the brakes completley and start turning and the car ofcourse - won't turn.

http://en.wikipedia.org/wiki/Circle_of_forces

If by some chance you didn't understand the point of this, you need to make smooth transitions from straightline braking to cornering and back, i.e. braking is 100 % steering is at 0 %, braking 95 % steering 5 %, braking 75 steering 25, braking 50 steering 50 and finally braking at 0 % and steering wheel at a maximum lock for that particular corner (doesnt mean full possible lock). Same with corner exit, when you wanna get on throttle dont slam it with the wheel turned, you start unwinding the steering wheel and applying throttle in the same "steps", how ever much u reduce steering that's how much throttle you add - so the forces on the tire are always at the maximum = the radius of the circle (max G for a particular tire).
