    Camber angles for GT3 ???

    Hi,

    could anyone suggest a good trackday setup for the camber angles front and rear ? I have heard so many different suggestion I am getting confused. Some say 3 degrees negative at front and 2,5 degrees negative at the rear. But other "experts" say the exact same figures but oposite.....

    cheers

    Re: Camber angles for GT3 ???

    A track day set-up will vary considerably it terms of driving style, track, car weight and how much you are willing to spend.

    I would suggest something like the set-up you mentioned, trying it out at a few track days and from there get it fine tuned to what you like.

    The GT3 is an extremely sensitive car, just by having the tyre pressures out by 0.5 bar can shift the corner weights out by a good margin.

    Also the GT3 has quite a bit of body roll so high camber angles are not uncommon, and stiffening the suspension will just make it worse.

    Best of luck to find a good set-up.

    try this:

    Infamous "Roland Kussumaul" settings...

    This is what I use as well as many others.
    GT3 settings

    Front axle:
    Camber: -2.5*
    Max camber difference, left/right: 5'

    Toe total: +5'
    Toe difference at 20* lock: -1*20' +/- 30'

    Caster: 8* +/- 30'
    Max caster difference, left/right: 30'

    Front height: 115mm
    Swaybar - 1 from hard

    Rear axle:
    Toe total: 35' +/- 2'
    Max toe difference, left/right: 5'

    Camber: -2.3* +/- 5'
    Max camber difference, left/right: 10'

    Rear height: 128mm
    Swaybar - 1 from hard
