My car was observed doing this this past weekend by another driver. I was not aware of it. He claimed to see daylight under the front inside tire.

Is all of the weight that was on this tires going to the outside tires only or is some going to the inside rear as well?

Is this a good thing or a bad thing. / I see porsches doing this too.

I know the cause too much front roll stiffness vs. rear yada yada yada.

Would car be faster if I softened the front / stiffened the rear?

Car feels very neurtral, turns in good, more forward bite would make car faster on exist. Exit speed is wheel spin limited

 

That is the result of the car being set up "tight". It comes from the rear springs and sway bar being softer than the front ones. Typical factoryish setup.

Kind of like, if you watch the FWD cars, they lift the inside rear off the ground, because the front rolls more than the rear. Those guys have to do everything they can to improve front traction because FWD naturally pushes so bad, on account of the front tires doing ALL the work; and when they stiffen up the rear with stiffer springs and sway bars, the front rolls and the rear doesn't, and the one rear wheel comes up off the ground.

Ony way to know if the car would be faster some other way, is to try it. Wouldn't be difficult or expensive to do, since all you'd need is rear springs and/or a sway bar (assuming that it does this over the long term, like sweeping type curves that stay at max turning effort for more than a half-second or so). I'd guess it probably would be; but that would depend on the course, the driver, the tires, and various other things. I'd expect it to be faster but easier to spin out at the same time. If it only lifts just very briefly just as you turn in, try stiffer shocks.

 

stiffen up the rear. ought to increase turn in and a if you get a better line coming into and thru the apex you should be able to increase exit speed. whats your camber angle?
braking earlier to so that you can accelerate in a straighter line coming out might be helpfull for exit speed and the original problem

 

SDIF,


Try reducing your front rebound damper settings. his will allow your tires to drop back out quicker and remain in contact with the road- Also allows for better front to rear weight transfer to get off the corner better.


If this does not entirely work, then try slightly upping the front spring rate and dropping the swaybar rate (Up on spring ,down on bar to equal the same overall front lateral balance as currently have.) to get the inside front wheels to stay in contact with the road. You may find out that you are more loose with better front grip- if this happens to be the case then raise the front compression damper rate also.

What type of differential are you running?

I ask because it sounds like you are using too soft of a rear spring to gain forward traction out of the turns. I've heard and seen more than few guys have to make some drastic spring changes after switching from a clutch or cone type diff to a torsens T2R or equivalent. They all said it tightened the car up drastically and allowed them to get on the gas much sooner. With a stiffer rear spring they were back to their old handling traits but much faster overall.

 

i love this sh*t, porsches lifting a front wheel vs a camaro is waaay different though, they are rear engine rear wheel drive so the weight pulls that front tire up on exit, camaro should stick the fronts way better, just think how hard it will turn when you get it dialed in!

 

I've seen pictures of bone stock 05' mustangs with the front wheel a good 12" off the pavement. It's just a combo of enough forward bite combined with way to little roll stiffness.

 

I rode in a friend's Viper and the one in front of us was lifting the inside front wheel. Only came up about an inch or so and carried it through most of the turn. Man that was a fun day.

 

Thanks for the replys

So where is the weight going that was on the inside front?

The Outside rear?
The Inside rear?
The outside front?

My guess is the outside front sees most of it.

Rear end is a detroit locker in a 9 inch ford.

 

It's going to the outside rear tire, that locker is half the problem.

 

what kind of tires you running man? gotta have some bite.

alott of people are saying this is a rear suspension issue, not stiff enough. most factory cars are set up to undesteer, look at the difference in FE1 suspension and WS6, wayy more rear roll resistance and stiffness, because people are more likely to be afraid of turns and too eager to punch the throttle on exiting turns. but a ws6 car is more likely bought by someone who knows a bit about driving so they set it up more neutral and faster.

i agree with bmmonte, stiffer rear springs so that the weight transfer is supported, however if you're having oversteer on exit (whats the power level and gearing vs tire size/compound?) perhaps a larger rear sway bar and less shock bound so that you add more rear roll resistance during turns but keep it stable over bumps, and then retain your current balance as you leave the corner.

 

Thanks again,
