How do you know when your rear end is about to break loose and lose traction?

I'm used to driving a Toyota Celica. The rear tires on it make a "chirping" sound when they're at the breaking point. I haven't noticed anything like that with the 7.

 

rev it to 6000 rpm's and drop the clutch......lol. they will chirp some how.

 

Just drive it and learn its limit. Dont go pushing it too hard with other cars around though mmk?

 

The only way I know is when I am countersteering and my rear view mirror is filled with smoke.


hope that helps.

On a serious note I do agree, it can be hard to tell sometimes you just have to feel it. I was racing and all the way through 2nd I was smoking them but the car stayed straight. I noticed the car wasnt pulling as hard and when I went into 3rd it bogged then I knew they where spinning.

 

You just need to do some hard grip driving, you'll feel where it wants to break loose at.

 

To be quite honest, I've pushed it through what I believe is some pretty hard grip driving, and only ever put the tail end out a couple times. I've yet to find any sign that it's going to break loose due to hard cornering. Of course, I can squeal the tires from a stop, but ***I'm most interested in whether the car has any signs that it is almost at it's breaking point due to lateral movement.***

 

my experince with my car is that it will hold a 25 mph on ramp up to about 50 before i feel the front start to reach their limit. that was with factory sized tires. and not the softest compound. now i have 225 and softer rubber it will hold to about 56. but a little more turn in of the steering wheel and gas full throttle will put the *** coming around no matter what.

 

just overpower the rear wheels

 

soft rubber doesn't always squeal when you get near the limits.


FC's are very neutral, they will tend to understeer or oversteer based on driver input and tire pressure.

 

Know your car. I just got back from a drift event last night, and I'll tell you this: there were 5 other FCs there other than mine, and they were nearly ALL understeering. I asked them what suspension setup they had, and none was much different than mine. I was able to have consistent oversteer just by knowing my cars limits. Drive it hard (in a safe place) and learn how and when it will react by steering and throttle.

 

^^^ ABSOLUTELY!

I had never really tuned my tire pressure until an event yesterday.. I set the front at 34/35 and rear at 39/40. Though it did help a ton, it still comes back to the basics: driver input. I had driven that tire pressure and experienced tons of understeer and tons of oversteer at the same points on the track. I came to realize that I was understeering because I was just mashing the steering input and throttle. When I took things smoother and softer, I began to learn how to master oversteer.

Driver input.


Hope that helps some!

 

If you are accelerating around a corner and you feel the backend start to slip from to much lateral force, gassing the car will straighten it out. If you let off the gas then the rear end will come around and you will spin.
Note: If you are driving a car with massive amounts of hp and gassing it hard will spin the tires then you will spin out. But if your car is coming around because of lateral g's and you accelerate harder (without wheel spin) the car will straighten itself out.

 

That's not accurate for a majority of FC's, which are still equipped with the factory DTSS bushings. If you lose grip due to lateral force and generously apply the throttle, 9 times out of 10 you'll spin out like a Supra in a donut contest.

 

That is if their DTSS bushings are still good and working. A majority of the FCs DTSS are probably not working.

The FC was built to grip and not slide. It actually takes a lot of weight shift and other stuff to get the rear end to spin out.

What setup do you have on your FC?

Well for me i can feel it in the seat. I can feel the rear start to slide and i can tell when its totally loose or just at its breaking point. But that also probably comes from experience and going past the grip of the tires.

 

I still have the DTSS and I've never had an issue with finding the rear grip/slip ratio. I've been to about 7 autocross events w/ the car and I've only spun it once, in dry weather- all due to a bit much gas in the corner. I've had the back end loose on many corners during the dry, and about half of the corners w/ a wet track. All the while I've never had trouble keeping it in control.

I find it grips really well w/ the DTSS and it usually allows me to hit the gas just that much sooner in the corner, while keeping traction. It just takes time to find the balance point. Find a local autocross location, and have fun w/ it.

 

if i give my car a mild launch from a dead stop (and by mild i dont mean a drag race launch but harder than just daily driving) and give it WOT when i shift into 2nd gear my rear end will fishtail everytime but eventually catch up to me.....
you can see my setup below and its nothing spectaculor

 

Tires and pressures play a huge roll....... when i used to have 235's good pirelli's on back the *** would rarely step out even on hard second gear shifts, but when i switched to some off brand 245's it would step out everytime i hit boost in second....

this was on my old old hybrird setup with 290 rwhp

 

not true for my fc... one night was racing... it was a little wet but not much... i turned out of a gas station got on it and tires broke free... i gave it more gas... and before i knew it i was facing the other way :-/ i felt retarded but it was fun... havent done it since then... its also been about two months ago. now i know how my car handles fairly well i know what takes to break the tires and what it takes to slow down fast.
without skidding :-)

 

When its wet is a whole different world then when its dry. When it is "kind of" wet its a whole different world then when it is really wet. Why? When its kind of wet oils on the pavement taht have been dried out get slippery again and dirt on the pavement turns into mud. When its really wet that stuff tends to get washed away.

Every time I have pushed the car hard enough to get the tires to break loose the (while dry out) the appropriate action has been to add more throttle. this causes the car the settle back on to the rear tires, adding weight and traction. The reason you lost traction is becuase you tires started spinning. They didnt lose lateral traction from being overload3ed, they lost traction from overpowering the tires on a wet surface. Had it been dry out you probably would have gotten straightened out.

Handling wise, I never had the back end break loose without me wanting it to. I hit about 60 or so in real hard on ramps. If I find the front end is just starting to slide, I let of the throttle a little and the front locks in even harder. Then accel some more Usually its the front I worry about. The rear I can handle when I make it slide.

I find it funny when someone comes up to me and thinks it was so awsome that I was able to get my car sideways from a stop. I do it for fun knowing I can any time but I don't ever do it to impress anyone, and to think someone is amazed that it can actually happen is even funnier.

 

sooo give it more gas and it eventually will all straight out?!?!...
weird but ill try it... ( in a big parking lot of course)

 

I dont think there is an absolute way to tell when the car is going to break loose. there are too many variables to tell when it is going to happen, such as weather, road conditions, tires, etc... I know that in ideal conditions (for myself at least) of a warm dry day with good tires, i can *feel* the car start to reach its point through things such as body roll.

 

If your back end is starting to kick out, I would not reccomend accelerating harder or letting of the gas completly, instead find a neutral throttle position. Meaning just enough throttle to hold the speed or just under the speed you are going.

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.

 

i no exactly what you are talking about. once i was driving like 6 hours after it rained a bit in the nearby park, which is pretty curvy, but nothing special....anyways i was actually being a good boy and driving normal, just drinking a soda, when all of a sudden while taking a left turn, my back starts sliding out! im like oh ****!! so with one hand im countersteering, and then i slide to the friggen other side!! so i counter again then again and this time im like "ohh **** that river is getting pretty close and i lose it and did a 180 and end up on the other side of the road facing the opposite way i was facing....

the whole time im holding the damn soda and tapping the gas to try to straighten out...lucky for me i didnt drop the soda (i have a blue 7, and it was a red soda)

other than that i never spun out even on this hairpin style ramp.....i still cant figure out what made me spin that time...i guess ill never no

 

/\ haha funny story.
