Once rolled is your car more drivable or does it even matter if rolled? Is hitting the turn just right the only way you get around the turn? Is traffic of any kind a problem? Does braking for a car leave your car flat with no steer or push? Is in the throttle the only left turn you have?--- If so you may want to improve your set-up starting with the j-bar location and angle matching the roll center to free it up a bit! This may loosen or tighten your car by your other settings! Each to be effected by other factors out of place! Rolling to even things out allows a balance of weights and drive power! Once there it can be easily switched left or right by the frame twist! This by use of castor in the front twisting the frame to cause rear steer,( drive thrust at the wheel by bar angle change), (pounds of traction by spring load), as well as front traction in steer by both front tires and rear steer being more equal in pounds side to side, drive angle's steer and the addition of roll-out actually working in or out of the throttle!--- 5 ways of steer at your control when rolled to a better balance of power! Never a one to one pound per pound but a close collection of steer factors to push or drag your car in any direction you choose to go, on or off the throttle with out upset of total steer while rolled! And yes spring rates, locations, preloads by adding weight, off-sets, air pressure and shocks all play a part in getting this to work! Once there, less roll out, rear steer, and bar angles are needed to stay hooked with a car that is most free to go faster any where on the track with less effort by the driver to stay in control of direction at all times while having all fours planted! Like steer, hooking up has five + ways of traction and left rear is only one!

Count all the ways your car has steer and then wonder why not be tighter with your set-up to have constant traction with less movement that adds even more steer! Steering a added car length off the corner or having to over come roll out down the straights is reason enough to run faster otherwise! Being able to keep your car straighter under you in the turn is free to add some tenths to your times!

Have you ever considered the right rear air pressure as steer in roll out once the weight has shifted or the fact that the forward bite point moved forward while you were hoping to turn! The fact that most try to steer with the left side and want the right to remain neutral has to have more steer than ever to overcome its demise! The same things that make a car loose can also be used to tighten it up in theory! They are many and some may counter others for control when going to extremes! A little here there and yonder in the total of only positive steer needs very little help to get there and back to being straight off the corner! Shock placement and variations along with springs and preloads can yield steer just by lifting the throttle! If able to hold more left rear than right, the lt. back drag will pull you into the corner with little roll-out needed! By then the roll has helped in opening up the rear and planting the right side to push the car left! If the air is a bit low, roll under will cause uncontrolled added steer in both directions at will leaving a car temper-mental in the corner making good use of the throttle out of the range of a smooth exit! The steer list is long in value and short on time when loose or tight is fighting Mother Natures gentle force to help! The term loose seems to have grown more to even me in my postings with all the things considered in steer!

Holding on to the traction of the left rear in turning during lift of the throttle, if not put there by drive thrust angles having to drop the left side before getting back into the throttle to make it turn and roll takes a bit of time off your laps! Being able to run in harder, farther and still turn anytime you choose while staying hooked by all four wheels holding there pounds gave us a bit of an edge over most other set-ups! All are complicated and to each his own as different things changed react differently on each car! This makes trying to help others very hard if not willing to commit to a total change! Those understanding the need for improvement were well pleased and a few even won a few more races! Just trying to let others have a choice in understanding the value of not following the pack in ways of getting things done! Question everything to a point of your understanding of how little is needed with the help of what going left offers! Trust your choices more by doing your homework first! Most things become simple with attention and not more left rear!

Discuss the forms of steer other than those made by angles and roll in your head and see what you have been missing in your set-up! |

If you car has 20+ ways of helping to turn left, how much steer is actually needed to get a tighter car to turn on a dime when ever you please? I worked harder at keeping one straight and under steering the rear to get off the corner with right side drive! This allows for added steering in the front to be able to pass or drive under most using left drive and excessive steer as a means for a lack of traction and giving up the bottom line coming off the corner! Constant traction without adding steer or needless roll is still a winning virtue in my way of thinking! Ask all you want in getting a good understanding of why it still works!

Toe in, toe out! How much does it take in the turn or down the straights? More out in the turn will help turn the ft.end but if not going back to a neutral setting in the straights it can cause tires to heat up and change your set-up or create drag that slows you down! Rolling your car and checking drag will not be the same as with torque applied lifting the front or hiking the rear! Walking up a bit to lift the front may help rear percentages but at what cost? I tend to go more toed out with my tie rod angles in mind for correction during ft. lift under throttle! 1/2- 5/8 and up to one full inch in some cases caused by spindle and ride heights affecting bump steer to get back to zero! Use your head and measure with chassis tilt and lift in mind for corners and straights if running 4 wheels on the track all the time! A bent ball joint or spindle knuckle can make toe out go crazy or the swing of the upper A-arm if different spindles are used or shimmed incorrectly! Moving a upper mount or different length arms can get the wedge of bump steer out of its working range quickly! Checked your toes lately? Make sure the little push coming of is not toe letting it ride out or up the track!

I was just reminded by a questionable subject of off-set placement that choices there too controls steer just by adding or subtracting a spacer in roll out between the tires width changing steer in drive factors but don't forget the other things it changed too! Go for a change for all the good reasons and not just the one at hand! Reason in all the effects and ask why it changes so much to start with! Should a right rear be so sensitive and in control of your chassis to start with instead of the driver if roll out tune is kept in mind? When only running a 1/2 inch roll-out to start with, it has to be factored in on making it work correctly and still turn on a dime down low on short tracks! Getting off the corner straighter some times requires less roll over, off set and roll-out to let the chassis to show what it needs elsewhere!

How many times have you seen a car show up and win that never seemed to roll, lift ,hike or tote a tire in the process of little to no steer in the corner?  Ideally if the rear is correct you can! Driving off of the wrong side will require added steer as well as running the rear open and a hike to three wheels to get the drive equaled out a bit! You may have more fun getting there than winning out front every race and having no one to race with! Even tenth place can get old too if not open to new or old things that work better! Ask all you need to get faster!!! |
