ok, I have heard alot about snap oversteer which seem affect fd's in particular and was wondering what this term really ment.

P.S. not sure if this should be in the race section or what so please feel free to move this thread around

i have not idea what the SNAP is for. maybe when we try to correct the oversteer, it is very snappy and the car tends to over-correct itself?

 

i know what over steer and under steer is, i just dont understand what people say by snap oversteer occuring a lot in fd's

 

You know how when you induce oversteer with the throttle and steering, and the moment you let off the gas and straighten steering the car snaps back (or jerks back) in the opposite direction just a little and then it goes straight again.

When I first got my FD, I managed to oversteer it and induce about 20 degrees of yaw away from the direction I really wanted to go. When I let off the gas, the car snapped back right away and the nose went towards the direction I wanted it to go.

 

"Snap" just means "quick" and often "surprising, oh ****!" and sometimes "surprising, oh ****! CRUNCH!". The car will rotate quickly when you unload the rear end.

what causes this? is this just becuase we over correct too much or just release the gas when we are suppose to stay on it?

 

both.

 

Or even, slide, lift, surprise, oh ****, WOW now I am going around the other way for a full 360

 

I think you have to be doing something wrong to get this car to "snap oversteer" in any type of street driving on dry roads. Everytime the rear has come out on me, it has been predictable and easy to catch. On a tight auto-X cross, it was the same.

On a road racing track with a modified suspension and/or way more power than stock, I suppose it may be easy to get the rear to step out hard and fast.

 

it happens. made me actually way oversteer and hit the curb. i HATE it. i heard the toe links help stop this.

 

True In my example I was on the track and my bad instintcs (first timer) made me LIFT & Countersteer when I should have just countersteered.

from my previous post-

"slide, LIFT , surprise, oh ****, WOW ...."

WRONG

 

I think driving slower through turns would help stop this.

 

I've noticed a tendency toward trailing throttle oversteer, but my car's always been pretty polite about it.

I use it with feints to induce drifts.

 

IMO, the FD is predictable and easy to catch in most cases. If you want experience some snap oversteer, try a FB. The rear hangs out a little bit then it's gone.

 

hmmmm, I dont think i have ever experience snap oversteer in my car then. I use to think that it was when you over countersteer in a slide and the car snaps back the other way (especially when you dont put enuf throttle and the rears grip again suddenly). In anycase, has anyone ever actually experienced this in a FD? When ever I drive, I pretty much know if I'm gonna loose it or not via doing thing which would actually make it do so such as clutch kick, clutch drop, power over, feint, hard braking or whatever other technique which would get the rear out. I think the only way to get the car to do this snap oversteer would be if you came in to a corner way too fast or trailbraked in to it and then lost it (things that newbie's do or other thing we do when we over estimate our cars).

 

What is feinting?

 

I've seen a lot of snap-oversteer discussions in the MR2 market. The guys will not be speeding, and be driving on wet roads and wreck. The situation is usually the rear end unloads, and when it does, it steps out very quickly, catching the driver unaware. This leads to a spin. There are a lot of guys that have quite a bit of driving experience and still have this happen to them.

The mid engine format causes this problem to be worse due to the fact that the majority of the mass of the car is near the center of rotation.

I don't think FD's have snap oversteer, but I could be wrong.

 

I've heard that slop in the rear suspension due to worn out bushings can sometimes cause it to get a bit unpredictable.
