I'm coming back to cali cali, back to my vehicle. Sooo excited, rain predicted for the first 4 days I'm back since it didn't rain at all over winter break. I also found me a new super secret spot, will report back with findings of how my car currently handles/how I drive in the wet. Maybe playing forza will have made me better in real life...

![]() That depends on the turn and how much balls you have lol.
Over 75% of the turns I hit are 2nd gear. Every now and then a 3rd gear entry will happen.

I was wondering guys with welded diff do niggas just power through turns since its much easier to drift? how much easier or harder are some of these techniques with and without?

My car has a Cusco 2 way LSD. I HAVE DRIVEN a couple 240's with welded diffs. Just didn't completely understand the physics of both.
Correct me if I'm wrong, but when you're on the throttle of an LSD, it's basically the same as a welded diff, no? Cause it's locked.... the only time it unlocks is when you're off the throttle.... meaning you only get extra grip off the throttle? Also, whenever I would take turns (not drifting) in the few 240's I've driven with welded diffs, it seemed like they wanted to get more sideways than my car with the LSD. Why was the welded more prone to oversteer if I was on the throttle during the turns with both cars? The welded is locked at all times, and I was on the throttle, meaning the LSD was locked throughout the turn..... ??? Educate meh! Hopefully I explained myself clearly. |

i may be wrong but i believe most diffs, regardless if 2way or not, have a locking point. that means that if you aren't putting enough load on it, then it will slip, when you exceed that threshold it will lock and perform as needed
weldeds obviously dont have that threshold, therefore if you are traveling 5mph vs 45mph, the diff is always locked

pretty much. think of it like this. welded= right and left wheel rotate at exact same intervals all the time. 2 way (and correct me if i'm wrong for those that are super into limited slips)= outer wheel in corner receives a percentage more torque than inner wheel (meaning that right hand turns, inner wheel doesn't want to spin as much as outer wheel, and the 2 way has the same locking on decel, just not as aggressive as accel, so that you can make sharper turnes, but not have a completely open diff feel), which is why it's more beneficial for drift cars to get grip off throttle, and on throttle, they get more grip cause they aren't at a 90 degree angle all the time (equal power distribution to both rear wheels). if this makes sense. |

welded is most predictable IMO,...and because i told myself id buy a 2way when a broke my welded,....ive been rockin a welded for like 3 years.....lol

lol, I think a spool is the way to go. I don't want shit to unlock, ever. I drifted a car with a 2-way and went right back to my welded. If my welded starts to go, it will be a spool.

^Difference between spool and welded? I thought they were the same thing, I mean WORKED the same at least...
I'm at work right now and can't watch the video, I'll watch the video when I get home. No speakers. ![]() |

this video is an open differential. one side has power.... Back to the FD thing.....it all has to deal with friction. We all know, the more friction the tires have against the road, the more it is going to accelerate. In drifting, it takes power to spin the wheels so you can get sideways, and the friction from the tires are what "push" the car around the turns. The diff allows for a car to have different wheel speeds through a corner. If both wheels rotated at the same exact speeds, they would have the exact same friction levels. When you allow one wheel to rotate at a slower speed, it is removing the forward friction, for lateral friction (grip). Imaging coming out of a turn on a race track (grip driving) and you had a welded diff, we know that the outside of the wheel rotates faster, but on a welded diff, they rotate at the same speed. So the outside tire gets 100% of the grip it can acheive, while the inside tire is actually spinning faster than the road, which in turn, is wasting friction. Now imagine that on a drift car that is sideways, the more friction you can get, the more grip you are going to see. That goes the same for decel. Let me know if that makes sense or need more explanation. and again, this is my understanding for diffs, i can be wrong. |

yeah i wasnt sure if the video covered more specific differentials or not, i watched it a long time ago and yeah i see it now, your initial wording was confusing me lol as much as a welded is fun, you cant get much better with one to be honest. having a proper diff means that you have to actually play with the throttle instead of just letting off so you dont spin

So you clutch kick right after turning you steering wheel? I was tryna get a small drift sess after work tonight and for some reason I really wanna master ebrake drift so I would come up to a turn press and hold my clutch in as I began to turn pull ebrake for about 1 second then let off clutch and counter steer with gas? Worked okay but felt like I was doing it wrong?

just gotta get the feeling,... try feinting a little harder into the ebrake. Lay on the gas after your fully confident the rear is sliding out. Then yeah,. steer with ur throttle

I googled this and found something but just want to make sure this is correct..
clutch kick is when you are going around the turn and your gas pedal is down all the way or whatever and while its down , you push in the clutch at the same time ? Correct? And what is "fient" exactly ? I've read about it but its always worded weird and can't do it when I'm trying to get sidewys. |

Clutch kick doesn't have to be done in a turn. It can be done whenever. All your doing is pushing in the clutch, revving the motor then dumping the clutch cause a drivetrain shock and breaking traction. (Providing there's enough power lol)
And feint is just weight transfer. Swaying the car to up set its weight to break traction. Look on YouTube. Lots of videos on this stuff.

So "clutch kick" is not when you have the gas pedal in and hitting the clutch in?? And ok I have or I should say had a stock sr and when I revv up the rpms to like 4500ish and dump the clutch , I start to red line ..and I don't want to blow a motor so when that's happening , should I let off the gas and ebrake? Or whaat? |

If you dump the clutch at 4500 and it redlines and your tires aren't spinning then your clutch is slipping. It may blow up if you continue to do that to your clutch.

foot on the floor like ur just driving threw the turn fast,. and literally kick the clutch,. in and out really fast. be ready to countersteer almost immediately.
id say start in a big open area, and just drive around in a small circle. Kick the clutch and go from there. work on donuts then figure 8's more practice you get, (like with anything) the more u'll get comfortable, and know when you need to, how often and how hard
