Default Under Steer or Oversteer

I figure that you guys into racing could answer this question best. Does the Crossfire tend to oversteer or does it understeer? I was pushing my roadster a little yesterday and couldn't decide and didn't want to push it further. Something about hitting trees and deer getting in the way. I think it would have to be under track conditions to push it further like you guys do.

Actually, I find the Crossfire to be a fairly well balanced car.

If I'm heavy on the gas in a turn it tends to "push" a little (understeer), but if you let off fast it goes right to "loose" (oversteer). Overall it's very easy to modulate between the two.

To answer your question easily............it depends on how you're driving!

It can be made to do either, but it is far more prone to understeer.

On the track, it will understeer until you give it gas. The more gas you apply, the less it will understeer.

Slow in, fast out. That's the rule for rear wheel drive cars.

You can feel the understeer/oversteer through the steering wheel. If you are understeering through a turn, the steering will feel "heavy". If you then compensate by pressing the accelerator, the steering will feel "light". It's really one of the only ways to tell besides actually powersliding through a corner.


Cool stuff.

"Understeer is when you hit the wall with the front of your car; Oversteet is when you hit the wall with the rear. Horsepower is how fast you hit the wall, and torque is how far you take the wall with you."

Stock, it will tend to understeer as long as you don't get into violent weight distribution (as soft as the Xfire's high ratio steering and brakes feel, they are pretty good for smoothing out driver input). But since it's fairly neutral, things like tire pressure and alignment will have A LOT to do with it (I run slightly lower pressures in the rear to promote oversteer).

Road Course and AutoX corners tend to be better regulated. But I think the car needs an LSD, a slightly bigger rear sway bar, and better shock absorbers to reduce the "bobble" and unpredictable open-diff traction that plagues the Crossfire during spirited driving on the street (if you are into that sort of thing).

That's about it in a nutshell Tazz. Good One.

Hey Tazz, between you and me what's up with apkano's avatar ? What's that poor girl doing? It looks like she might be tying to unplug a toilet with a plunger. Don't tell apkano I asked.

i am a track driver it is **** from the factory to understeer because of treadware and suspenssion to overcome tihis tires notincluded you may turn your alignment out approx. 1 turn in to give u more tire surface to push note hard on tires thats the price of being fast

Unmodified suspension here... understeer.

That being said, I will be lowering the front pressure about 1 or 2 psi and raising the rear pressure about the same amount to try and compensate when I get to the track on the 11th.

Cheers!
