Hi I would like to know which of these options is best for a car that is to be used as a daily and 1x DWYB (Drift What You Bring) per month ?

Also which of these is hardest to learn drifting in ?
Which is easiest to learn drifting in ?
Presumably welder is the easiest, then LSD, then open diff

Is it possible to drift well in open diff btw eg figures of 8, transitional drifts etc.

I am a total newbie wrt drifting btw.

Thanks very much :-)

You would be mad to weld a diff on a daily.
Why not try your car on a DWYB day and see how it goes?
An LSD is alot of money.

If you have the space, get a 2nd car. You're going to break stuff on the car especially as you're starting out so you really cannot rely on it as a daily to get to work.

Could you elaborate a bit more please on why welder is bad idea ?

As for LSD you need a LSD or welder for drifting don't you ?

Not looking to crash the car just learn about car control and RWD and to have fun on private track.

So is learning with welder easier than LSD ?

On a car you're thinking of continuing to use daily?

Do you know what a diff does?

Here's a starter :- http://auto.howstuffworks.com/differential.htm

What type of car is it? A welded diff is probably the handiest option but will do your head in on a daily driver.

Also if the weld happens to break on a corner you'll most likely end up in a hedge.

This really is the wrong forum to ask about this but basically if you just want to drift and nothing else yes a welded diff is the way to go. But as you want it to be a daily driver it will drive you mad within 10 miles everyone will look at you stupid when parking due to both wheels turning at the same time making some horrendous noises.

Also what happens when you hit something in your daily car on a drift event it does happen so don't kid yourself it wont.

You assume a welded diff will bring oversteer

It can also bring bucket loads of understeer

My RX-7 has a locked diff - it can be a handful but is manageable.

Definitely a Welded Diff for drifting, cheap and cheerful, annoying to live with it daily, lots of tyre grinding etc when parking up and U-Turns are difficult but not impossible.
You can drift with an LSD - its just not as easy at first - once you learn it would be just as easy.

Weld it up sure, but seeing as you'll be actively reducing your available grip by 25% by causing one tyre to slip please advertise your journeys in advance so I can stay well away from you on the road.

A more sensible first step is to paint the wheels green apparently.

I already got a rebuilt LSD 40% but just wanted to be sure I made right decision.
I think I have as don't want the grinding noises.
And learning with LSD is that bit harder than welder. So mastering with LSD then should I ever use a welder should be a stroll along the beach!!!!

Imho if you are going to weld it you might as well as buy a proper made to spool and have done with, at least it has one benefit of a slight reduction in rotating mass and of course you have your old diff to put back in if you want.

An air or electronic locking diff is another option.

Good idea, it's a lot of fun, probably cheaper than drifting too.

Drifting in your only car is a bad idea, if you need to rely on that car to get places. Everyone who I know that has a drift car spends a fortune replacing things they've bent and broken, and their cars still looks like Fallujah bomb wagons.

Drift days can get pretty lairy, especially when performing tandem drifts in close proximity (known as "Hanging out the back of XXX", where XXX is the car in front), if one car moves out of sync a prang is highly likely. As with all track events, other people's mistakes that cause damage to your vehicle will almost inevitably be paid for out of your own pocket. Some of the drift day videos I've seen look like Mario Kart, only it's not Koopra Troopa shells flying about the track, it's body panels, gearbox bellhousing and con-rods as knackered old stboxes blow their engines and drop their oil from the stress of being ragged mercilessly on the limiter lap after lap.

By all means, go drifting if it really appeals to you, but go in with your eyes open if you're doing it in your own car. It will be used up like an old Stretch Armstrong doll in no time.

My 328i has a welded diff. No issues at all for everyday driving, apart from some wheel hop/screeching at lower speeds when manoeuvring. In the vast majority of driving it's just like any other car.

Find an outdoor track and go when it's wet. You can go sideways all day long. Not very good for lap times mind you laugh

Buy a different car if you want to drift. I speak from experience of owning an E30 325is with LSD. Was a decent track car but rubbish at drifting. Only had 170bhp out the factory so probably 150 now. You really want at least double this or to run the car on space savers.
Basically there was no adjustability. You had to get everything bang on or it just wasn't going to happen. Too few revs and it wouldn't spin the tyres, too many and you need to back off which then means you don't have the power to get back where you want. Essentially it's maximum attack or nothing and max attack was often too much.
The only time I got mine sliding nicely and predictably was on a bloody hot track day where the tyres had pretty much turned to mush.
Though having standard suspension was not ideal either, you will probably want to stiffen yours up for drifting.
Even the Drift King himself says low power cars are the hardest to drift but if you can master it in them you can do it in anything. Also he suggests an LSD.
Open diffs are a nightmare as they are not predictable or smooth and often only spin 1 wheel so no good for drifting. A welded diff does make things easiest but I would not run one in a daily driver due to the interesting handling and pain it will be in tight manoeuvres.
