    ok this is gunna sound really unco but meh im asking anyway. can anybody explain chassis weight distribution to me please? i mean i keep hearing everyone saying that u shuldnt take away too much weight from the back cuz it'll screw ur handling yet before you enter a corner ur sposed to brake n put as much weight on the front as possible... wouldnt it be good to take the weight outta the back n have it all on the front in the first place? and if having weight in the back is so important why are mr2s such bitches to drift? if anyone can clear this up for me please that'd be great

    Mr2's are such bitches to control as once your sideways or conering hard the weight of the engine in the back/mid mounted works like a pendulum and wants to throw the car around.......... if that makes any sense....... lateral G - forces & weight transfer...

    it something along the line of, if you dont have the any weight on the back then you cant really transfer any weight to the front. like a see-saw. if theres only one person on it then you cant get the see saw to rock. i guess you could but it would take twice the effort.

    just like the body of a car having no weight in the back, meaning that when you do brake and your front brake grips there is no weight to (in theroy) be thrown to the front. now there should be some weight transfer to the front while braking cause it well help in the tyre gripping. how? by the weight being transfered onto the front hence, pushing down on the trye. more trye touching the ground constantly = more grip.

    then you have to factor in suspension. thats why suspension is so important. shock and spring loading. bound and rebound. i think are word to use. your shocks absorb the weight being transfered and the spring and the rebounding (shocks pushing upwards) of the shocks help transfer the weight back to the back of the body.

    thats a really brief on weight transfer.

    um now mr2 are prone to oversteer (ive heard) cause the fact is that the weight is all in the back (cause of the engine)
    now its wieght ratio front to back is like 40/60 (jsut an estimate). mr2 like f1 cars are design to grip more then drift. it is possible to drift tho takes alot of skills and balls . they are better for grip racing cause i would imagine that you brake and down gear to enter a corner and then you acclerate out of a corner like f1 cars. in theroy they should have or be able to get better exit speed cause, as you put the throttle on the weight trasfer to the back or in the mr2 case the weight is already on the back, agian more weight on trye equals more grip. hence more grip eqaul more speed can be archived.

    hope this sorta help.

    if you want an indepth expliantion on everything to make a car handle get a book called "how to make you car handle" by Fred Puhn its a very good read, its old but still very very very good.
