Gene got out hj-s shop nurual ard reised the lefi: rear of his car one degree and lowered ttre right rear one degree, and reports thlngs are back on arr even ke e1 . The operation on the rear torsion bars ca:: be done by alnosi ar{fone who can turn a lrrench provided sorne guidance is available. John Snyder, Potorec Region, conducted some adjustEenl on hri-s rear torsion bars and lrrote up the details and explained a few techalcal polnts as he went, along. Our only preface to Johnts artr icle ls that you should not play around 'r:ith the torsion bars just because you have notlring else to do on a Sirnday afterrroon. We suggestthat jJ you lo:row there is a li.st, a droop snoot, or /cu want the rear end to hold in corpetition, then go ahead and do the job.

The radius arm (uhicb is attached to the end of the rear torsion bar) when hlngJng^free, should have an angle of from 6f" to 7, doi.rn from the l.rorizontal. Many Porsche owners have erperienced the tendency of thelr car to oversteer, that 1s, to follow a path of progres$ive1y decreasing ridiue in any one given turning position oJ the steerjng rheelp requlring the driver to ropen uprr on the steering wheel 1n order to steer around a curve of constant radius. l'lany have al-so e:rperienced the tendency of the car to "wander" at higher speeds, particularly under the influence of a crossuind. These conditions r€y in large part, and in many case, be eonr pletely overcotne by decanrbering the rear wheels. : L ^-; _'.j-r, ^,,+ gc -^ out ano Du;r a nerr pair. of .f;.cnt -uor_ --+ s:c:- :p:'irrgs. if no*", read '-::e res-; of tf:is a l f h c u g h a s l i g n t c e c a n t e : i n g o f th e : ': -l e; :,e e l s :-=e e v e n j J r a n e w c a r : : , a ; , 'b e q u i te . :3rz:ax]g. lhe effect of decarnbe:.ing or: the oiers:€er=g teridenc."*is rather +.ecjtnlcai and need e:i c::-eern us here, suffice it to say that ciec"--::e:irg the rear ;heels of a porscbe, .rdnether '.::e car be new or used, has a pronounced"iffecl :r the oversteering tencie::cy and rtrilL decrease j-t in all cases, causi:.g ihe car to have trcre cr less a neutral_ steering .uendency. ?he :::cice::tal effect of decanberGg which causes ..i_ to have greater directior:al stability i=" is easily understandable when it is real_ized 'i:at cecamberilg the rear wheels lov.ers the rear enC of the car aad that lo"*ering the rear end of tte car will tend to create i greater degree of caster of the front wheels, cester in *.91f"-being the anount tha"" th; kin4rjns are tilted toward the rear of tbe car at thelr i.q:per ends. fhe greater the degree of caster, k-e g:'eater tendeney for the front rfieels to reroirl in or return to the stral.ght-ahead positioa, hence greater directional stability. .4lo'r,Ler factor contributing to directibnal sta_ is the proper anount of toe in of the lielty lront wheels, rdrich is, of course, a requirenenl mdgl any circunstances. &'e urlterrs auJomobile, a J-953 coupe, possessed a great tendency to overdte;r, a pre no-,:src€d degreq ,of .directional instaUi i i ty, and a.l'so a tenalency- to-shj-rm6r.
