Re: [Fot] inside wheel lift

["Marx Christian tr4-racing" <chris@tr4-racing.de>]

I had this trouble too at my first race:

Like a sailingboat at strong half wind.

I cured it with swaybars at front and rear and I brought up the front
suspension spring rate.
At the rear I still use the standard leaf springs.
Have a look now:

    ...it seems that I'm lifting the rear inside wheel too much when I see
photos
    of the car in tight
    corners. There still seems to be too much body roll. I assume that it
    is the springs. I'll be adding additional rate this year to the springs
    in hopes of reducing lift. I plan to go to 600 lbs/in rear and at
least...



    This seems counter-intuitive to me. If the body were fixed to the rear
axle
    (unsprung) and encountered the centrifugal force of cornering, the inside
    wheel would have to lift, since the car's center of gravity is above the
    axis of the wheels. However if there was the ability for the body to roll
to
    the outside under those cornering forces, wouldn't that alleviate the
    overturning forces being generated, thereby allowing the inside wheel
more
    opportunity to stay in contact with the road?
