HI OLDS BUMP IS THE AMOUNT OF TOE IN/OUT YOU GET AS YOUR FRONT SUSPENTION TRAVELS UP OR DOWN. TO CHECK IT MEASURE FROM YOUR A FRAME TO UPPER SHOCK MOUNT BOTH SIDES WITH CAR AT RIDE HIEGHT.PUT CAR ON STANDS. THEN REMOVE SPINGS AND SHOCKS PUT SUSP. BACK TOGETHER W/O SPINGS AND SHOCKS.PUT JACK UNDER A FRAME AND GET TO YOUR PEVIOUS MEASUREMENT AS YOU RAISE OR LOWER YOUR TIRE WILL TOE ( THEY MAKE A SPECIAL GAUGE FOR THIS AND YOU REALLY NEED IT FOR THIS ) BUT YOU CAN MINIMIZE IF EXSESIVE .BASICLY YOU WANT YOUR TIE RODS LEVEL AT BOTH MOUNTING POINTS .[RIDE HIEGHT DOES EFFECT THIS], YOU CAN SHIM AT SPINDLE IF YOUR SETUP ALLOWS OR CHANGE PITMAN AND /OR IDLER ARM . THIS CAN TAKE A LOT OF WORK BUT YOUR CAR BUILDER LIKELY HAS IT CLOSE YOUR BEST BET IS FIND SOMEONE WITH A GAUGE AND LET THEM HELP YOU THE FIRST TIME .YOU WANT AS LITTLE TOE CHANGE AS YOU CAN GET.
