Hi, I'd like to pick apart how the toe settings work in GT4. All contributions welcomed! TEST METHOD The FR test car was a Holden Monaro with RM tyres. The FF test car was a Honda Civic with RM tyres. For front toe, I tested acceleration of an FR car, acceleration of an FF car and braking distance. Rear toe testing was done for acceleration of an FR car (ie the driven wheels), braking using the rear wheels and top speed of an FR car. FRONT TOE THOUGHTS For rwd cars, I have found the main effect to be the trade-off between turn-in and exit understeer. Negative toe = less turn in (bad), but less exit understeer (good) Positive toe = more turn-in, but more exit understeer. Negative front toe also improves acceleration (remember this is NOT the driven wheels in this case) and braking, but the effect is minimal. (I was surprised that the acceleration and braking was best for -1, I expected these tests to give the best results when the wheels were pointing straight ahead) For fwd cars, the above "turn-in vs exit understeer" effect is also a factor. But since the front wheels are also needed for acceleration, the far greater effect is on power-down: positive values improve power-down (which effectively reduces exit understeer), so fwd cars benefit from positive front toe (I have found rwd cars prefer a negative or zero value). However, above a certain point (+2 in the Civic I was testing), the increased exit understeer (as seen on rwd) starts to outweigh the increased power-down. Sure, the improvement in fwd acceleration times are very slight, but around Autumn Ring, the overpowered Civic had much better power-down exiting tight corners. REAR TOE THOUGHTS I found the main effect of rear toe to be general under/oversteer. Positive rear toe is like stiffening the front stabiliser, negative is like stiffening the rear. But what about the acceleration/braking/top speed side effects... ...FR power-down is clearly improved with positive rear toe. Braking is too close to call, so I reckon negligable. And the top speed test showed no increase in rolling drag when the wheels are pointing slightly inwards or outwards. Although I didn't test it, I would expect this to mean rear toe has no effect on acceleration for an FF car, since it appears that GT4 does not model rolling drag. I also had a quick play around with rear toe in a Ruf Yellow Bird. The same basic change to handling was noticed, but the effect was minimal. This makes me think that the main factor for handling in this car is the weight transfer.
