How to unstick rear end

[deeldoo]

In a safe environment, open area, etc just to preface.

In snow i found it pretty easy for obvious reasons to have the rear move as a function of the peddle and it doesn't take much power to get it going.

In the dry i am finding it kind of hard to do a whole lot, anytime i dig into the pedal somewhat gently i can't unstick it. If i really push into it mid corner i end up letting off, car starts bucking and i can't seem to must anything smooth.

For any of you seasoned folks who can have the rear end kicking out, how do you smoothly get this procedure done?

Is TC on or off?

Off of course

Running with TC off and 275 MPSS I found it very easy to break the rear loose anytime - if you’re too smooth with the pedal that definitely won’t help, but generally giving the pedal a quick jab mid-corner does it. If you can feel yourself on the edge of grip then it’s should be pretty easy. My buddy with an E90 M3 calls my F82 a drift machine

Turn traction control off. If you can't absolutely destroy your tires with little to zero effort after that then please let me know what tires you're running because I would love to try them

Potenza RE71 R, i can still get them unstuck but not controllably, i can't smoothly break it away, i have to dig into it but at that point they dont stay unstuck for long and i am ricocheting my head

I need those tires then

As everyone said, the F8X is always ready for a smoke show. But the best thing for you seems to be getting some cheap tires (if breaking loose is your goal) and a heavier right shoe.

I have 285 re71r’s and they require EFFORT to break loose. Truly. I find it mind blowing when people claim otherwise. I’m even more mind blown that Bridgestone were foolish enough to cancel the line.

Depending on your warranty status and risk tolerance, spending $300-$400 on a used Bootmod3 license from a reputable forum member would make it much easier.

I'm running stage 1 93 with 295 PS4S tires and it's more than happy to spin the tires any time.

Good luck and be safe!

So you have the same experience? Truthfully i am running stage 1 and the first 15 or so minutes i can take it out and with some jabbing in second gear i can get the back end to jolt. I can't use first as it's too short and will redline.

But after 15-20 minutes and making it step a few times, i can't unstick anything.

Maybe it really is the tyres but i also feel it might be a bit of fear in me, sometimes i get the bucking kangaroo effect because as i am about to break the rear end loose i end up backing on and off the throttle jolting the whole car.

This is why the mash the throttle technique seems to not work for me currently.

Might have to really get this done in a school environment or wet skidpad. I have alot of confidence in snow as it doesn't take a lot of power and the snow will allow the slide to continue while in the dry the moment i back off the car regains the grip violently

Bottom line aggression can unseat the stickiest of tires. Couple that with abuse and sure, sideways desires be fulfilled. But just punching it after the tires warm, best of luck. I’m running Cary Jordan custom E85 map as well.

This for sure. Running 285 PS4S and I can smoke those bitches at will.

Same! Stock tune and I can make those PS4S melt without TC

Re71R are extremely grippy.
It's too bad they stopped making them.
They will be offering a new model called RE71RS but they have only been available in japan and austrailia last time I checked.

The RE71R is a 200 treadwear semi-slick tire. I could pull about 1.3 G on the ring with them in a corner. you might be able to get more also, thats just what i was doing.

When they get hot the rubber melts and kinda conforms to the pavement making them grip like crazy. They make a sticking sound as well when you roll forward.

This was helpful! You've convinced me. There goes my mid year bonus on Japanese RE71RS

I'll report back

Why would you expect the stepping on the pedal "somewhat gently" would cause the car to lose traction? Turn steering wheel at or near full lock and floor the throttle. I guarantee your car will spin out immediately. If not, there's something wrong w/ your engine.

Turn into the slide that you are trying to create. Get 2 cones and set them 30ft apart. Drive through them in an infinity loop circling around the cones. You should start sliding as you get faster.

I do a lite drift every morning onto a 8 lane street one corner from my office.
Some times it’s wet, dry or damp.
I have a really good feel for how much gas pedal will bring the rear around for a long drift.
I’m running 305/35/18 Nitto NT01s, on the rear M4.

So you are completely leaned into the throttle (TC off) with good amount of steering angle, you break loose, and while still full throttle it snaps back mid slide? No expert over here, but either you are too high in the rev range and hitting the limiter, not enough steering or you are coming off the throttle too quick/not smoothly enough. Torque curve hits pretty hard, so understandable that it comes unstuck suddenly.

I run Michelin Pilot Sport full slicks on track, and if I am not careful my back wheels over overtake my front very easily from throttle input.

My issue is i come off too quick but not on purpose, i am not trying to but the slide initiates so violently that my whole body gets swung around. This is what i am talking about if i just mash the pedal with alot of angle the car snaps out too quick.

But with too little throttle input i can't unstick them, it might be also that these tyres are probably not suited for smooth slides

Try a cold morning. Summer performance tires are sticky in the summer temp. But on a cold morning they are like plastic.

Even better is a cold wet morning. Super easy to get smooth light tire spin.

I wouldn't say all F8x can do a smoke show. My 18 F83 Comp with the mpss tires in the rear will NOT break loose with tc turned fully off (long hold, not MDM), in a straight line at least. Yah coming out of a corner it break will if I push it. I don't know if whatever software the dealer may have updated to, assuming the software is not original, and put in it really limits boost in more gears such that I can't break tires loose.

I will say that I'm looking for a local Dyno to make some runs on to see what power I'm putting out; car is bone stock, but under full warranty for a bit here still.
