    Cool my rally... search fun touring setup

    hi to all, i'm omix from italy
    I'm working on my rally to improve the touring side...
    here's the steps...

    starting from a used stock

    first test shows a funny car but ugly stock tires, with foam was better.
    After that i start to work on airflow... (thanx to prototyp posts)


    revo wing and homemade underchassis, they work very well and r2hobbies tires was great! but too soft and with very short life.
    Stability grow but i still have problems...
    The under chassis is too big and i broke it on a jump, springs are too soft for on road, weight balance are not good... and the walls are hard




    here's the actual step, fit in body underchassis (i'm working on new ones) and integy springs kit (now set with strongher). i can't test it now but i'm working on next step...

    New tires, improved underchassis, weight on front for balance, new custom alluminium chassis.
    Aesthetics: the body is not painted, i tested wrapping vynils, next step will be with leds

    i hope to be useful for someone as someone was useful for me

    I've really been wanting to do an under body. I've been looking at prototyp's posts as well. The reason I haven't made one yet is I have no place that's smooth enough to allow the body to be so low to the ground without destroying my work. I really to like the MERV wing on your Rally. Do you notice that wing giving off any help in high speed runs as far as aerodynamics go?

    i found a small fit under body good in light offroad and water cause it slide faster on rock etcetc, with wing the car is more stable in speed run straight and in large and speed turns, as stock in low speed.

    with both i found a better grip in high speed but rear tires become slick a bit faster XD

    Fwiw, Stratocore is quite durable. I'm six months in, now, running (and occasionally crashing) on the street with the same splitter/floor/diffuser rig. I've had to reattach some strakes and make a set of splitter brackets but other than that, very little in the way of mending. Its a little ugly now but still works very well.

    I do run pretty low, that central front skid is less than a quarter inch off the ground. Little pebbles aren't much of a problem, but anything over a half inch gets the car airborne.

    As it is today... Note that the splitter's been folded up in half in some frontal crashes a few times. The diffuser design transfers any rear impacts to the full length of the rear suspension arms, so also quite robust:
