yeah it's always funny when I get my tires mounted. once the tire hits 40psi...the guy hands me the nozzle to keep filling it up with air. Kinda funny. If I get hurt...he get sued. lol.

that's what I would do... hand it to you and run and duck for cover... never gone past 45psi here and even then they look explosive lol I can imagine 80psi

I dont have any videos, sorry! My issue is the exit from the corner, lets say a left 90. Car will be sliding counter clockwise, and i want to drag out the drift then switch to a clockwise slide but keep it aggressive and angled. I am sure it has to do with the steering wheel movement and how i carry the moment about my front end. Ive recently had a little more success with it, so maybe just some more practise ![]() |

ok here is the story...i have always ran federals on my car and i decided to change it up a bit so i bought some new tires (rear:delantes front:haankook) yesterday. it feels way different, i can feel more roll with these tires. The rear tires grip way to much and my car feels heavier then before (clutch kicked it), do i just need to bump up the psi?
my set up stock sr welded diff i am on some 17x9 225/24/17 all around 45 psi in the rear i have no idea what the psi in the front is

try this...and hopefully it will make sense. so if it's a 90 degree angle, you can either 1. Take a shallow entry line that keeps up your speed, and once you get to the absolute top of your power band, turn in a little to get more angle and scrub some speed. Or two (which is good for the power guys) take a wide late line coming into the apex, so that when you clip the apex, you are in your mid power range, so when you go to exit the apex, you are not at full lock, but more so mid angle....allowing you to then start picking up speed...the more speed you get towards the end of your power band, rip the e-brake, or add a slight amount of more angle (keeping on throttle). Believe it or not, but the guys with power, have a lot more ease with doing this. As the tires will only provide a certain amount of friction. If you spin the tires faster, that doesn't mean you add friction, but more so take away from it. So if you can imagine the tires getting less traction, it will allow your slide to further extend at a higher or lower speed. Hope this makes sense a little. |

so instead of me telling you what your car is doing, i'll explain what you are feeling and why. so regardless of the front tires. Lets focus on the rear tires. Imagine drag cars. Soft rear suspension so that when the power is put down, the suspension absorbs the shock, and allows the power to be put down. There is your answer on the rear tires. Federals have a "SS" steel sidewall, which means that when you hit that throttle, it has very little compression. So when you put a tire on there that has a softer sidewall, it's going to compress and give grip. Raising the tire pressure would allow for less compression. And at the same time, the tire with more tire pressure inflates like a balloon. The contact patch gets more narrow, allowing for your width of your tire to narrow a little bit. You feel the car sway, because the sidewalls are now compressing under load. So if you pay really close attention, there will be a split second of turn in where you don't have response, and then all of a sudden you get this huge amount of rear grip. The second you shift the weight of the car to the other side, you'll have a bigger delay....cause now that tires compression has to travel past the center point, and to the other side before it compresses. Just like your suspension under weight transfer. As far as the front tires, it really only makes a difference in turn in and mid-drift traction. Alignment settings can make this setup feel better, but at the same time, you work with what you can. Air up that pressure, and have some fun, just understand, more air..makes it feel like you are driving in the rain. So be careful. ;D |

lol... I just hate when people don't look past their question, and find out the answer. If everyone would sit there and actually think about what's going on, and the reactions of somethings, we would then have some really good conversations about driving. Like why is drag racing so important to drifting? Or better yet, why does CF run positive rear camber on the rear? Is it cause the suspension compresses under acceleration and then becomes a ZERO degree camber tire? And he runs aggressively negative camber, is that cause also under compression it tends to go a little positive...and when you lift, you need that biting traction to keep up speed? His set up baffles me, so when I see him, I shall pick his brain...TOMORROW!!! |

240's are made for drift, little did nissan know just what they would start lol. FC's are a b*tch to slide in, never tried a miata though

Yea, made me miss my s13. 240sx's are like the easy button ha. That fc was also setup for auto-x. Had to run super shallow angle. The car really showed me that I need to work on my throtte control more so I felt I actually learned alot from driving it. I actually really want to drive it again and master it since it is so hard to drive you know. Sometimes driving an easy car isn't as fun! |

Yea, I can't wait till we get my friends e30 drift car up and running he snapped a rocker arm first run. I want to get some seat time in that I am sure its a totally different world in that thing. I can't imagine anything being easier then an s13 to drift unless it drives itself ha. |

So I guess I'll bump this thread with a question of my own. I put a Kaaz 2 way LSD in my car this past saturday, set to 80% lock per Kaaz's recommendation with what I was going to do with the car, and I'm having a bit of trouble getting used to it.
I've learned to drift somewhat with an open diff, which pretty much required a lot of speed and really "throwing" the car, along with lots of clutch kicking to really get it to stay sideways, and I'd gotten pretty good at doing so with what I had. Now that I've got this LSD, I'm finding that the car takes more or less the same amount of a flick or clutch kick to get it going, but it comes out a lot faster and harder than what I'm used to, and as a result, my mental "programming" for countersteer is late, and slow, not to mention kind of frantic as I try to keep up. I'm assuming I just need to take this somewhere where I've got a nice open area and really get a feel once again for what the car does, and reset my muscle memory for what I need to do when initiating a drift. Keep in mind I've only been driving on this LSD for 2 days or so. I'm just wondering if anyone has any kind of tips to offer me, or if it's really simply a matter of just "doing it" and getting a feel for it. I spun out for the first time today in a very long time (not including track driving) and it's kind of reset my limitations of what I felt comfortable with doing. Kind of made me stop and realize that I needed to figure this out before I ate a curb or something. |

THIS. You are used to one wheel rotating, while the other grips the road at the speed it needs to. Now you lock under accel, so you are feeling its slide out more. Just have to get used to it. Once you get used to that...then start adjusting the car. |

My 2nd time at the track, open for criticism.. I will note the car is on a 235/40 up front on a 9.5 +12 wheel, with my 15" spares on the rear. They sure did smoke a lot lol.. I have my collars removed on my car, the front is as low as my d2's will let me go... I almost want to raise it, I binded the steering at the end and spun, but it was a decent run overall..
My entry started awesome but I straightened then e-brake.. and idea on how to keep up the momentum for a sideways entry? |
