| Cross post from EvoM ... http://forums.evolutionm.net/showthread.php?t=318213This post was specifically enlightening ... - fatcircles wrote:
- "you get a +3 or +4 addition in front grip from the camber curve improvement but a -1 in front grip from the "additional weight on the tire" part of the equation that comes from having a larger bar, so overall traction in the front of the vehicle is increased. Of course body roll is decreased, but as a bonus turn-in is quicker.
The car feels like it is understeering less because the limit of grip is a lot higher, while in reality at the limit the car is actually understeering a bit more. Hence why some folks say the car understeers less on a bigger front bar, and then others who haven't tried it bust out the "book and GT4" knowledge and proclaim that a bigger front bar will make the car understeer more.
...
Increasing just the front bar, the front tires see a larger percent of total weight transfer which increases front tire loading and reduces front tire grip slightly (and also the opposite effects on the rear tires)... BUT you also get a reduction in roll which reduces how positive your camber goes in hard cornering for a large increase in grip. The end result is a good increase in cornering grip with perhaps a very slightly higher bias towards understeer. Now, before a thousand people jump on that last statement, let me explain. I know that people are also putting on big front bars and saying "I got less understeer". I would contend that what their butt-dyno is telling them is not the whole truth. The real story is, the increased grip (from roll reduction) allowed them to go faster in places where they previously had understeer. So yes, perhaps they experience understeer less dramatically than before, but the bias has still shifted towards understeer more... it's just that the limits are now significantly higher so this bias is less apparent. I'd say that the front tires see a moderate gain in grip while the rear tires see a significant gain in grip."
