: Understeer

Anybody have any suggestions for dialling out understeer using tire pressure and/or suspension alignment? In fact does a performance/track alignment exist for our cars?

I am looking for a fairly simple solution to reducing understeer without resorting to actually changing the suspension through say new parts such as replacing the roll-bars.

Thanks

More negative camber in the rear and 0 toe in the front is a good start. I've found that the trick to avoiding understeer in this car is early braking and then guiding the car through the corner with the throttle.

I know you say you didn't want to, but I hear the Hotchkis sway bars dial in a little bit of oversteer.

Increase front tire pressure, decrease rears.

As much negative camber and positive caster up front with slight toe out. As much negative camber on the rear with slight toe in.

autox taught me that, and it works great...


Throttle


hell ya....and the hot bars do help as well...but mainly, just do the driver mod, it'll get rid of most of your understeer ;)

Strictly speaking "more negative camber in the rear" is not correct. This will make the rear "stickier" relative to the front, and increase understeer.

Reuction of rear toe is the easiest way to get oversteer without any other changes. Also the other guys are correct with pressure stuff.
