Welded diff... my 2010 temptation

[Paolo-LoveGT40 Modelworks]

Going around for hours in car cemetery I see nearly no bmws at all have the lsd istalled.
The few ones I found are the biggest ones for 328/M3 and the price is stellar (and I absolutely dunno the inner conditions, diff from outside doesnt say so much)

So now I am seriously considering to buy an ordinary one..and do this:

Welded Diffs Fact or Fiction

they also say it is ok in ordinary driving.
Dont u have any significant experience in daily driving with a welded diff on ordinary streets?
Shall i be ready to be a drift king at every turn?

Of course the original one from my car will be saved apart.

Would love to know your impression guys, u know much more than me.

Does anybody of u ever welded (if possible) a transaxle over a gt40?

LSD is my new drug....just think is different from the lsd form the 60s

I haven't had a welded diff on a street car, but had one on a Datsun 280Z racecar. No way I would ever have driven it on the street with that diff. Every corner you do you are scrubbing sideways. OK at higher speeds Sucks for street use.

It's much the same as driving with a spool. It'll want to plow in corners and chirp a tire when turning...if you're lucky. The main thing that I would have concerns about, as I have seen it, is the failure of one of the welded pieces and losing traction to one wheel while under hard acceleration. You could very well find yourself in an unwanted and uncontrolled hard turn....Now for the negatives....

ooops...so really better I ask before then...

...moved it for you Paolo....

Welded or otherwise locked diffs are terrible for road use. Particularly in the wet...

I'd not run a spool or welded diff on a street car. As with lots of these other fellows, I'd used them in race cars and there they have negatives as well.

I ran a welded diff on a BMW 5-series on the street many years ago. It was "welded" because the car had sat outside for about a year and the friction plates in the LSD were completely frozen together.

It was completely undrivable on the street. Sharp turns produced horrible tire squeel and highly unpredictable tracking. Even moderate turns were no different. And, high speed turns, well, you better have your seat belt on and check to make sure there's an air bag ready to go in the steering wheel.

Other than that, it was great.

Just my personal experience.

HI Guys, I have run welded diffs in 4x4s where you think they would be great, But even there they are unpredictable and give the vehicle a mind of its own. They are very hard on axles and even worse for CVs the "Chirp" that the guys referr to is the tyre skipping in the turn and this shock loads the axles and CVs something terrible, you can't turn unless you have massive wheel spin and use the throttle to power slide the car. The only places for welded or spool diffs is the Drag Strip or the dirt track and even they use wheel stagger to get some degree of "turn in".
I hope the answers here have helped
