    When trying to rid your car of that dreaded understeer, most of us go for altering the springs before altering the ARB but is this the way. Or do you differ from the norm and alter the ARB before touching the springs.

    Decisions decisions !!! opinions please,

    ARB, then springs :). Springs are trickier to get spot on, so if I need a quick fix I always adjust ARB.

    I'm far from 'clued up' in the tuning area. But I treat them as [almost] separate aspects. - Springs for accelerating and decelarating at corners. ARBs for coasting/holding speed at corners. Therefore I honestly don't find any advantage either way...Well, that wasn't much use was it? Sorry.
    While on the subject of understeer, if I may I'd like to ask what your (or anybodys)approach to understeer is. The thing that concerns me is the way some cars kind of shudder when understeering. I have found this to be most evident in the GTpro class, especially the Aston Martin DBR9. Is this avoidable or does the shuddering actually help the braking process in some way?

    For understeer I usually adjust the toe-in for front and a little in the back. To get some traction out of the turn reduce the lock helps.

    I'm no pro at tuning but this is what I am learning and doing lately. It helps

    Depends on the understeer.

    For understeer on fast curves, I lower the wing.

    For understeer on slow curves, I raise the rear ARB and lower the front ARB.

    Corner understeer= lower front ARB or/and higher back ARB
    Fast corner understeer= Higher caster value

    peace

    ARB Jarrod, as explained before by others too. My usual way of making an initial setup: set all springs to minimum, then adjust the ARB for car balance, if it is for some magic reason still not possible to set, then make adjsutment of slow bump and rebound, if still not enough, then touch the springs (1% of the cases, depends also on the car).

    Thanks Attila for advice:) I've never set all springs to minimum in the beginning. First I set ARB then caster and wings. Springs and bumpers only sometimes when car is still understeer. I must try your way.

    Attila.
    I do exactly the same as you always starting with minimum spring settings I also have brake bias set so that the car will come round under braking and then adjust the bb so that the turn in is good. Once I have the feel of the car how I like I fine tune with the arb's and wings.

    On the beemer i go for the springs first, then ARB and the bumps/rebounds are the final tweak of the process

    First i alter the arb's , then the springs , and i do them separate.
    lower value toe-in on the front.

    i found out that a negative toe on the rear works for me too.

    Well as a noob to set ups and after doing quite well with default, I am at the point were from default setup I adjust ARB, then Camber, then Lock/Coast/Preload to try to get it as smooth as I can.

    I still have lots to learn.

    I follow an old set up guide for GTR2 that suggests decreasing the Front ARB for more grip in curves. Still no idea what I'm doing but it works. I just test, sort gears, then do ARB's and check tyre temps after that sort the camber.

    like Atti
    I also set the (front) springs to a minimum for the front wheel drive cars. This is to make the car take less weight pressure on the front and making the tire temperature as low as possible (and so also try to safe more of the tire in longer race).

    I generally take the default settings and soften the end of the car that needs the grip to make the car predictable to me. If it understeers, I soften the front. Oversteer, soften the back. I generally do both ARB and springs at the same time.

    Predictability generally means I have more confidence in knowing what the car's going to do next, and allows me to push harder. Confidence is more important to me than outright speed.
