    a thick rear sway bar will help. Stickier tires, LSD. Just off the top of my head.

    thats about it. A rear sway will make your back in get alot more rotation.

    Interesting.... weird how you need to modify the back to fix the problem up front... ha ha.... im picking up some 205/60/hr14's here in the next week or so im hopeing this will help the problem.....


    curious, how does the LSD help? :unsure:

    Bare with me, this is my first venture into suspension... kinda learning as i go here.

    to reduce understeer*:

    -stiffer springs in back

    -more pressure in rear tires than in front

    -(technique used on some awd drift cars) run narrower rims in back than ones in front with same size tire.

    -get rear tires that offer less traction

    -sway bar; reduce roll

    and to increase overall cornering speed:

    -lsd

    -lighten the car

    -stickier rubber on front and back

    **btw, a lsd can actually work against you in cornering if your tires can't handle it, thus causing more understeer.

    great but his problem is too much UNDERsteer..unless you were just trying to point out that last bit about the LSD. yea i agree that LSD would make understeer even worse.

    my suggestion would be stiffer springs up front, or if you have adjustable coilovers just raise the front (or lower the back) a little.

    dude i think you mean thats to reduce UNDERSTEER.

    Rear tires with less traction will cause you the ass to swing out, that doesnt reduce oversteer.

    More pressure in rear tires will also help counter understeer.

    :yes:


    :no: to reduce understeer (invoke oversteer) you want lower tire pressure in the rear and higher pressure in the front.

    more pressure in tires will cause less traction, and in a fwd car you want to take away some of that rear wheel traction. lowering tire pressure in rear and increasing in front will cause oversteer.

    this really depends on the specific tire

    and i quote from the chart on that exact site:

    suspension adjustment:
    Front tire pressure higher

    Affect on vehicle's balance:
    Less understeer by reducing slip angles on most tires*
    ___________________

    suspension adjustment:
    Rear tire pressures lower

    Affect on vehicle's balance:
    More oversteer
    Except with BFG R-1 tires.

    They will grip more and oversteer less if the pressures are decreased within a reasonable amount.

    END QUOTE


    that is exactly what i have been saying. to reduce understeer you need more tire pressure up front and less in the rear. i have done this on my own car so i know it is correct. now if you guys want to keep arguing about it. be my guest. im out.
