STEVE / ALL - - -

I'M NOT SURE THAT ADDING CASTER WILL CORRECT THE "SHIMMY" BUT ADDING 1/2 DEGREE TOE-IN SMOOTHED OUT MY EXCALIBUR BY ABOUT 75%. OF COURSE IT DOESN'T DIVE AS QUICKLY INTO THE TURNS AND HAS A VERY SLIGHT "FEELING" OF FRONT END FLOAT IN THE TIGHT "TWISTIES" NOW BUT THESE ARE BARELY NOTICEABLE.

I REALLY BELIEVE THAT THE PROBLEMS WE ARE ALL EXPERIENCING WITH "SHIMMY" - PARTICULARLY IN THE 60 - 70 MPH RANGE - ARE A RESULT OF VERY MINOR TIRE IMPERFECTIONS AND ARE AN INCONVENIENCE BUT NOT REALLY SERIOUS. THEY APPPEAR TO BE EXACERBATED BY THE FACT THAT OUR CARS ARE VERY LIGHT COMPARED TO THE LOAD CARRYING DESIGN CAPABILITIES OF THE TIRES. ON A HEAVIER CAR THE IMPERFECTIONS WOULD BE LESS NOTICEABLE.

I'M GOING TO FOLLOW THE ADVICE ON JIM C'S POST AND HAVE THE TIRES AND WHEELS "PROPERLY" LOAD BALANCED.

Y'ALL HAVE A REALLY GREAT DAY,

BLACKJACK
