![]() ![]() This is also known as “understeer.” A car that is tight will typically feel more stable and easier to control, but will also be slower to turn and less responsive to steering inputs. This is also known as “oversteer.” A car that is loose will typically feel less stable and harder to control, especially at high speeds.Ĭonversely, when a car is described as “tight,” it means that the front of the car is pushing or not turning enough in turns. When a car is described as “loose,” it means that the rear of the car is sliding or drifting outwards in turns. At the rear, the tyre with the most static load on it will become overloaded and lose grip producing oversteer at a lower G turn than the opposite, lighter loaded rear wheel.In the world of NASCAR, the terms “loose” and “tight” refer to the handling characteristics of a race car. The physics is the same: the front tyre that carries the most static weight will become overloaded and loose grip causing understeer at a lower G turn than the lighter loaded front tyre. This would put the rear of your car in the wall, or see the car diving for the centre field at least, on an oval. For all other rear wheel drive cars the quickest setup is generally neutral on turn in and slight power oversteer on the exit. I think the confusion is between the physics and the end effect making a powerful rear wheel drive car with limited grip go round an oval quick is best achieved with understeer. ![]() The banking only changes how much is required - the basic concept is the same on a flat oval, it's just a matter of degree. 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. 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. which is the opposite of what Tony C said - but I agree - as does Lukin. ![]()
