How do you know your FC's rear end is going to break loose?

When you're turning, trying to grip though a corner, though, how do you know when you're about to lose it?

Well I may not be the most experienced driver but when I am sliding and I give it gas.. the rear end stays out. If I let off slowly it comes back in nice and slow and if I cut it...it goes crazy swerving all over the place.

I have never heard if you add power you gain grip....and it straightens out AWD and FWD yes... never for RWD.

Now as far as rain... if you add power in a corner you slide I personally just cut the power and it will straighten up nicely.

thats my experiences.

Now if your trying to grip and you want to know when it will break loose...

1) you have to feel the body roll
2) add gas and feel it settle then slowly feel it step out

or

1) go in hot on the gas let the body roll settle
2) slowly let off the gas and feel it step out

Take it to autocross and youll find out. I found that if on throttle it would tend to understeer and letting off progressively let me come around corners quicker. I'm in a stock S4 GXL besides intake and exhaust, cheapo street tires on the car, i ran 38psi up front and 45 in the rear.

your correct you dont gain grip when hitting the gas, however as we all no if your sliding out and hit the brakes you will lose control and start really spining, however pulsing the gas a bit while counter steering will help you regain some control...or at the least keep the same line your car is following

There are some situations where this could not work for you though but im not an expert and im not going to go there.

Im speeking from my own personal experience for the way my car handles.

Im not saying floor it. Then all you are going to do is break the tires loose. Im talking about giving it a measured amount of extra throttle to get the cars weight to settle to the rear tires.


Finding that neutral point is definitely the key though. thats what you are looking for. when the rear end starts to breaks loose you give it a little gas and the weight transfer will buy you some extra traction. If you are understeering you can back off the throttle a touch and the weight transfer will give you some extra grip up front.

If you arent smooth in either case you will likely end up with either massive oversteer or understeer depending on the situation.

With front wheel drive the its almost always advisable to just back off the gas some and the front end will come back under control.

In this car that is primarily a function of the tires you have choosen to run.


Soft rubber isnt going to give you a lot of warning. Harder rubber will make more noise at the limit. Some soft rubber will break traction with little warning, but will do it progressively so you can react to it. Some will just let go with no warning at all. Harder tires tend to let go all at once but they scream at you before doing so.

In either case with the FC the DTSS (passive rear wheel steering) at the limit traction feels weird. As soon as you think the rear end is going to step out the DTSS kicks in and you find the rear end tucking back into position and you have quite a bit more traction. It is a very weird sensation the first few times you experience it. Anyway, with the DTSS the limit is harder to find because as soon as you think you are there you gain more traction.

If you want to know when its going to come loose take some NASA vehicle control sessions. You will get to push the car enough to get any idea of what it does and how your tires react in a safe environment. For instance there is a car control clinic at VIR the weekend of the 15th for $50. look for something similar in your area.

I'm just oging on personal experience here. In a sustained curve at near the limit I can feel the back end startng to break loose and I will give it a touch more gas to get the weight transfered to the rear tires. Suddenly the rear will tuck in.


I am by no means saying give it lots of gas. Just enough to transfer weight. If the rear has already broken this isnt going to do much.

How would I go about finding one of these in my area?

Anewconvert is correct. When the back end starts to break free from LATERAL force (Not tire spin) accelerating will force the weight back to rear tires and transfer the load from pushing you sideways to pushing you forward. I would guess most people have not had the rear break fee from lateral movement on the street, you would have to be driving on the edge of the FC's limit. Most people with track experience will find out quickly that you have to accelerate in those situations or you will spin out at every turn. Now I have never taken a car on the track with the rear steer so I cannot speak for that (the RX's is disabled) but it DOES apply to all RWD cars.

THis even has obviously already passed, but this page should help you keep up to date to find the next event in Ohio.

You will never be able to answer that until your assometer has been calibrated to the car. The only wat to know is to drive it and see.

Easy. Any time I'm at over half-throttle.
