Loading up the front right, on left hand circuits, or the front left, on right hand circuits, will achieve this.
over-steery) you have to get out of the throttle, which is a sure way not to win. Though not an oval racer, from what I understand the usual setup for torque rich/grip limited racers (NASCAR/ASCAR) is that you want the car set up to understeer slightly with the power on, so you can keep your foot in round the turns.
CROSS WEIGHT OVAL RACING SERIES
I am currently racing in an Oval series turning left, and have my car currently set with a 52% cross weight (RF - LR), Howe reccomend up to 58% for their ASA/ASCAR chassis. Phoenix please read Tony C post again and you will see both he and I agree, Lukin says it'll turn to the right. In either case, without a limited slip diff you will find it difficult to get the power on until the car is pointing straight - which is quite often a slower option than sacrificing turn-in in favour of a good corner exit speed. If a front wheel drive car it will more easily pick up the front left wheel on left hand bends. more than 50% is carried on the RR/LF and less than 50% on the RF/LR)Īdditionally, if the car is rear wheel drive, it will tend to spin the right rear on right hand corners, or at least give the limited slip diff, if you have one, some work to do.
If the car had a neutral balance before, it will now tend to oversteer on right hand turns and tend to understeer on left hand turns.Īs evidence, in oval racing (all left hand turns) the rear right is often 'jacked' up to give the car a natural left hand bias. So always check that last if you decide to go with the adjustable links that is, i'm not sure what your rules allow.which is the opposite of what Tony C said - but I agree - as does Lukin. With my old car I found a setting I liked and never changed it, but keep in mind any time you change a tire or make just about any adjustment you are changing your pre load on the sway bar. The front sway bar is another usefull tuning tool that all the latemodels constantly adjust. A lot of guys use them as a tuning tool throught the year to chase the track changes. I use them quite often with a new car when finding the balance. If you are allowed spring rubbers they also help in the same way and you dont have to alter your tire pressures. I will sometimes run them as low as 13psi or high as 30 cold when things arent quite going my way. I try and keep my tires in a window of 15-28psi but that varys a little. If my right rear is already at 28 cold then I dont want to upp that tire ny more, so I would use the other method and drop the left front. You kind of have to decide based on your tire pressures and what you feel comfortable with.Įxample, If I wanted to loosen my car up I could either drop the left front pressure or raise the right rear pressure. putting air in the left front will solve a loose condition as well cause it shifts weight onto the right rear (which obviously needs more weight since its slipping) the saem as droping air from the right rear does. If it has a push I'll increase the cross weight by upping the left rear. If its a little loose I'll drop a few pounds from the right rear. These vary tho depending on how the car is handling. I typically run 28 in the right front, 25 in the right rear, 15 in the left front and 20 in the left rear. New guys do this all the time, they throw 50 psi into the right front and it works for about 3 or 4 laps and then gets some heat into it and the car is junk. You dont want to balloon your tires up to 40 or 50psi cause they'll never stick. It really depends on the tire but I never exceed 28 cold and they usually get up around 32-33, 35 hot max. You're on the right track with pressures. If not atleast check it for piece of mind.
It tends to vary once you start playing with the suspension geometry with longer/shorter control arms, even camber can throw it out a little. It should be pretty much bang on and usually is but I always check it anyways. Yes, basically you plot a point 13" foreward from the center of the tire when its strait and then again when its turned and measure the diffrence I guess is a better way to put it.
