I have a problem with a lot of my own setups in places like suzuka R200. My setup will feel fine through the rest of the lap but when I get to the last part of the corner before spoon (where it gets a little sharper) the back end will just fly away unless I back off the throttle.

When I apply a decent tune from one of you guys this problem is usually rectified. So my question is - which part of the settings would directly combat the above effect?
 
As one noob to another ;)

I'm just proposing some things to verify if that's what the knowledgable guys would say (so what i say is not the answer, it's probably fault ;))

- lower the front or highten the back. (beware the bend you refer to is on the top of a dune, we don't want the chassis to touch the tarmac ofcoz).
- tighten back springs / loosen front springs.
- + toe rear / -toe front.

Again penta, i'm well aware chances are you are less of 'tuning layman' then i am ;)

The corner you talk about is one of the most difficult corners to me, please solve it :)

1) FALSE - no no, you'll be removing weight from the back wheels and moving it into the front where most of the weight already is, resulting in more front end grip, and less rear grip. But doing this helps general turn in under deceleration as your front end may bite better. Turns like 200R it could cause trouble.
2) FALSE - big no no, tightening your back springs means the weight won't shift over your rear wheels under acceleration, bad for a turn like 200R, you don't want a light rear end, thats the problem.
3) TRUE - *bing bing bing* we have a winner, the rear toe being the most important of the two as it increases stability if set to a + setting. It may never mean full throttle all the way through (not without downforce anyway), but it should help a little.
 
Hi Dragonistic,

Thanks for the input, the first one i had indeed completely wrong, i meant the other way around (really ;))

With Nr 2, wouldn't that depend a bit on the current spring settings? but seeing your definite no to tightening the back, is the NO to loosening the front just as big ?

Nr 3, i'd be hesitant to use that, as i've been (self!)taught to first sort stuff out with suspension and only if needed mess with the toe. Wrong approach?

Thanks (and sorry Penta, for highjacking your thread to my own benefit (i hope you benefit too ;))

Indeed toe and camber is often the final touch, as for loosening the front, it's fine and can help you're front end bite when cornering in. Top race cars have super solid suspension because they have such grippy tyres and smooth surfaces to run on, we have heavier slower cars on road legal tyres. The problem is finding the balance between drivability, speed, body roll and so on. So don't go thinking what i've said means soften the suspension all round because then your car will be to soft and possibly unpredictable due to drastic weight transfer, which could upset the balance of your car.
Softer suspension can make your car less responsive to, think like when your driving fast and you hit a bump (real life now) your car may respond to the bump and still wobble a bit after the bump has long passed. There is no one specific solution with suspension, it largely depends on the car and driving skill/style.
