    Buggy setup help!

    Well I have an mbx5, bought from ue-maxx, and I can't seem to get this buggy to handle the way I want it to. I'm having troubles in the turning department the buggy wants to push on and off throttle. Diff fluid is 5front 7center 3rear shocks are 45front 40rear sway bars are all the way out. I've messed with the caster alittle but have not noticed much improvement. Running s7 with mugen clutch 1.1 springs and panther switchs on hard packed clay oh and the track is indoors and small, very technical. All help greatly appreciated.

    I think I'd start by droping the rear diff fluid to 2k maybe down to 1k. Lighter shock fluid will help transfer weight a bit faster and will help out as well. Not sure how far off from the stock set-up you are every where else.

    Generally - not always, there are exceptions - you want heaviest fluid in the front.

    Front diff fluid is the turning response, the thicker it is, it will make it turn smoother and give it more of a reaction mid to the end of the corner.

    Center diff is how much power you want to use. The thicker it is, the less give it will have, and under hard acceleration when the weight is shifted to the back, it will allow less power loss to front end from wheelspin.

    the thicker the fluid in the rear diff, the more the back end will want to "drift" into the corners on sharp turns.

    A common starting ground is Front to rear:
    7K, 5K, 3K, or
    10K 7K, 5K
    again, every driver has a different prefrence, so experiment with that one.
    Tires can have alot to do with handling as well.

    Adjust your toe in out to so if yoiu look at your buggy from the top your front tires are like this \ / but you dont want that much toe out maybe 1 degree that should turn into cornors quite easy then. I also heard mugens arent the best on indoor tracks{lack of steering} but are superb on outdoor tracks. If im wrong someone correct me but i think there is a steering mod out there for the mugen ask wayne or tony.

    FWIW...

    Give this a shot, your current set up sounds like it's made to push.

    5/7/1 diff oil
    400/350cps mugen oil (or 35/30 shock oil)
    Rear ackerman position
    Short wheelbase
    All caster clips in rear of arm (upper front arm all the way forward)
    -0 lower anti-dive
    -1 rear toe plate
    1deg anti-squat insert

    You can try middle Ackerman to smooth out the steering but back position will give you more responsive steering.

    Thanks alot guys I will make some adjustments and go from there, is their something I can read to tell me what affect each adjustment makes? This is my 2nd mbx5 and I can believe how much different it is from my 1st. What do you guys think about the switch's for hard pack clay, anything better? Thanks again.

    The Switch 2.0 is the tire of choice on our track here in Ohio. The original switch is a little boxy, if thats a word and tends to catch every little rut on our packed track. Clay compound is usually my choice, however if the track is dry and dusty the softs work better but wear out very fast.
