I don't know how to tweak the setting it doesn't feel any different racing with almost any settings. Except for the gears ACS TCS or the Differential things.
well then that's half of it done
ok, suspension. This is where you make or break the car, in my opinion.
generally speaking, softer spring rates, bound and rebound settings, and sway bars will promote more grip at the end you're adjusting. This means, if you want the backside to step out, give it stiffer (numerically higher) settings
You'll have to play with this yourself and see what suits your style. I tend to like my cars set pretty stiff, but I've seen a lot of soft settings posted on the forum. Soft settings with large amounts of body roll make the weight shift from side to side more noticeable, and more pronounced in a feint induced drift. Though this is not to say that it cant be done with a stiff setup. In the end it all depends on what you get used to.
moving on,
I've found that negative rear toe gives you more cornering stability (ie.more stable drift) and makes it easier to induce oversteer. Positive front toe gives you touchier steering (more response). Overdoing it can make the car a bit of a handful. I seldom go beyond -1 in the rear, or +1 in the front.
Also, more negative front camber will give you better ability to countersteer. It accounts for deflection in the suspension while its under cornering load, or in other words it helps preserve the contact patch of the front tires. The same holds true in the rear, though I find it less essential.
this is all very loose and general terms though. The nerdy engineering student in me could go on for days about load distribution, and force analysis garbage, but i dont think anyone would be too interested to hear it, especially when its been done so many times before.
Here, have a read over M-Specs guide, it should be helpful.

Oh, and brake bias. Just set the rear higher, thats about all there is to it. give it like 18-22, and keep the front at like 8-12. Play with that til your hearts content.
I really think it would be beneficial for you to post your FC settings, along with what's ailing you. Someone(s) with some experience with them will no doubt show up to look at it

but i think the best thing is to just pick some settings that sorta work, and then leave them alone.
Practice with them for a long stretch of laps, like 15 or 20. I go at least 10 laps on new settings before doing any major adjustments so i have a chance to adapt my style to them a bit. (unless its so blatantly obvious that there is something major wrong)
Its hard to pass a clean judgement on new settings after only 2 or 3 failed laps. You havent had a chance to change your driving to match the new settings in that short amount of time.
...thats my rant
again, best of luck
edit:
also, (and this may just sound like common sense, but i'm posting it anyways) try your best to only change 1 thing at a time when you do make settings adjustments
this will (1) give you a more intimate knowledge of what each setting does and how it effects the driveability of the car.
and (2) changing spring rates and sway bars at the same time in the same direction (for example) will almost inevitably result in you changing one or both of the settings back to their starting location, and trying them again individually. Avoid this whole sticky mess and just do them 1 by 1 in the first place.
