E30 welded diff

Tue Jul 10, 2012 3:06 am

BTW handing out legal advise without being a member of the Bar is illegal, matters of Law are different but know doubt you know that you must be a lawyer, or do you know the relevant Acts and Statutes relating to this, just because the insurer doesn't stop you doesn't make it legal.

Lsd and open are for Pussys!! lol

Tue Jul 10, 2012 6:16 am

I would of assumed welded diffs where illegal

just like all other pikey mods like cutting springs

Tue Jul 10, 2012 8:30 am

I am neither angry nor closed minded. Just correct.

Welded diffs on a road car are for retards. Plain and simple. How can fitting something that MUST cause the car to lose traction be a good idea? You guys are obviously such talented drivers that you could never lose control.

I'm surprised its not a BMW factory option.

Welded diff = i do not have the skill's to get the rear end stepping out with a open diff

Tue Jul 10, 2012 8:52 am

Your all idiots! Why would things like landrovers have lockable diffs? To put the power to the floor equally! driving an e30 in the snow would be much more difficult with an open diff.

Anyone can get the back end out with an open diff but again you'll just get stupid 1 wheel drive.

Tash you seem to be barking out the law so why not take your own advice and stop lecturing people!

Lsd is stupidly expensive, but i guess it's ok for people like yourselves who get a perfectly good e30 that just need a bit of TLC and you frag it and scrap it! Your all so worried about what people are doing with their e30's but that's only because you want to offer them peanuts and frag it!!

i think that's something to do with going off road ?

Tue Jul 10, 2012 9:00 am

what i meant by it was they obviously can't be illegal

Tue Jul 10, 2012 10:03 am

Only centre diffs on Land Rovers lock. Try locking your Land Rover centre diff on the road and see what happens.

If any diff is locked there must be a way to scrub off the speed differential. Off road it is no problem. On the road, it must involve a loss of traction.

yung-gun, if permanently locking the rear axle was fine for road use, then why would every single manufacturer for the last hundred years go to the time and expense of researching, manufacturing and fitting such a complex piece of kit to every single car they produced?

If all you wanted was to make the wheels spin at the same rate constantly, two cogs is all you need. A diff is an enormous extra cost, especially considering the suspension workarounds that have to be engineered to cope with the weight of the unit.

So argue all you want about how they're "fine", but 100 years of motoring and all the laws of physics are against you.

Tue Jul 10, 2012 10:23 am

Ohh all the hostility in here haha

Tue Jul 10, 2012 10:27 am

In your opinion. But when your pulling away on slippy surfaces like i do alot (living in the country) a shitt open diff doesn't help. Yes i want the arse end out ALL OF THE TIME! Yes i want to burn through tires Yes i want to rattle it to death Yes i want to stack it and buy another one and keep on with that process until i can no longer afford to!

Title of the thread wasn't E30 Welded diff, come on in and be an opinionated prick! or am i mistake?

Tue Jul 10, 2012 10:45 am

Cheers ;) Smug arse!

Tue Jul 10, 2012 10:50 am

Don't for get about selling your bumper before you stack it

I won't. be careful tho mate, someone could have you done for giving me financial advice and not being an accountant ;P

Tue Jul 10, 2012 11:01 am

Yung go and find out the difference between legal and lawful before you try to be clever.

Your arsehole may one day thank you for it.

Tue Jul 10, 2012 11:39 am

I know the difference thank you for the attempted tutoring!

Tue Jul 10, 2012 12:18 pm

its not exactly dangerous in my mind ! and if somone wants to weld a diff clearly its for skidding and tgey dont care about tyres n that there gonna be skiddin on the streets , heck i have pals with s14s that cone with lsd n theyve still welded them up so its not about having money ect there just shit for the job !

Tue Jul 10, 2012 12:56 pm

Go on then have a stab at it.
A line or so will suffice.

Tue Jul 10, 2012 1:02 pm

Only a hero welds an LSD

Tue Jul 10, 2012 1:26 pm

So we are all going to agree to disagree then.
Basicly it's really down to each to their own

Tue Jul 10, 2012 1:43 pm

Isn't everything? Freedom of speech and that lol

First of all. BMW slippers are shit. I know, because i have owned cars with them in. So that leaves me with £1500 Kaaz 2 ways as the only real option, and im sure as shit not spending that kind of money on sub£1000 car when a welder does the job 90% as well.

That'll matter for nowt in a civil court if you crash and the third party knows how to go about dealing with idiots who think the road is for their shoddy, bodge special and twatting about like tarts.

Best go tell all the guys with quadbikes that their vehicles are illegal then and they should scrap them right now.

That would be lovely if you were correct. Unfortunately you are point blank wrong. I have checked with both my MOT tester and insurer and a local traffic officer, he said as long as it was insured it was legal.

Wrong. Again. FFS.

Rear diffs are 100% lockable on many 4x4s. And at anything but slow speed tight cornering the movement in the tyres takes away any slip in wheels. There is none. At anything above car park speeds you cant tell if a car has a welder, once again showing your ignorance.

This a simple case of modified for purpose. The same applies to any vehicle with non standard parts on this forum. BMW didnt put it on there, so why do you need it? Oh yea. Because you are modifying your property for YOUR needs/wants.

What Gibson said.

And what Morpheus said.

What a bunch of puristic (when it suits) imbeciles you really are.

90% ignorance and 10% internet knowings - no wonder this place is the laughing stock of the BMW world.

Much like TD is the laughing stock of the drifting world.

But at least we're accurate.

Whereas this place seems atm to be peddling fiction and opinions as fact. The Zone used to be full of good info - now it's full of mistruths and scare-mongering.

For shame, for shame, something good ruined by know-nothing, opinionated, closed minded zealotry.

Tue Jul 10, 2012 2:52 pm

I never said they were illegal. I said that *on a road car* they were for retards. Cross axle diff locks do exist on off roaders and 4x4s yes - for off road use only. But not on Land Rovers as someone suggested.

The only way a locked diff can scrub off the cornering speed differential is by spinning one of the wheels. Whether that's in mud or on tarmac, it doesn't matter. That is what's happening. What do you think.all the skipping at low speed car park turns etc is?

Why did the diff in the OP lose its bolts?

Why would you fit a welded diff? To skid about like a cock. No other reason. Do race cars have locked diffs? Proper race cars, not driftcock spec?

Tue Jul 10, 2012 2:57 pm

the thing is, an e30 LSD it's a 25% 2 way diff, on the overun the wheels act in the same way as they do under acceleration. Fine really, it's a road car - 40% lock is available but not that popular.. IMO 40% is going to be much more suited to the way most people will want their e30 to behave. I'm assuming most people hate on the e30 diff because 99% of the time your £300 diff will be nigh on worn out.. From new, they're a different expeience alltogether!

I have to say that 2 way 100% lock aka welded, ain't good. Assuming you're fine balancing the rear under acceleration, fun no doubt, tire scrubbing action all the way, but as soon as you have a situation causing you to suddenly lift mid corner, that's when you realise the LSD is the tool for the job - MEANING, you can use the car to it's FULL potential on road. I'd be uber cagey threading a welder down the B roads.. Just one S bend 20mph too strong and it's ta-ta!!

Boyd is correct, landrovers, the centre diff locks up - F&R open axles lock together, the result being you can move off with either a front or rear off the ground, not one of each at the same time.

Air locking diffs (for the F&R individually) are available for landrovers, which is essentially a 2 way 100% lock F&R - coupled with a centre lock makes is act like a tank - using this on the road is definitly not cool

Not sure on the law surrounding welded diffs, but as far as insurance is concerned, instant void, which in the eyes of the law means you lose your car, a big fine & 6 points.. Possibly more, especially if it involves a 3rd party.. Not saying you shouldn't use one but....

Don't know why there were no bolts. probably because they were taken out? impossible for the bolt to rattle all of the way out! they're blocked by the output flange.

Original cars are absolutely beautiful. and cars modified beyond belief are Amazing too! the difference between me and you is i appreciate engineering and I'll listen to anyone's angle so long as they aren't PREACHING! and it doesn't have to me "oem" to interest me!

In what way is welding a diff engineering to be appreciated?

Absolute rubbish. Total tosh.

We had an E30 impounded which had one fitted - and when we picked it up from the police they didn't mention a damn thing - after they'd driven it themselves down 20+ miles of Pembrokeshire's scariest roads.

I'm sure they would have mentioned summat. After all, they mentioned the rear tyres.

Stop talking crap on subjects you know naff-all about.

When it comes to setting a car up for 'fast-road' use or whatever crap it is you are a professional in then we'll ALL pay attention.

At the moment you're just making a gibbon of yourself.

Tue Jul 10, 2012 3:18 pm

its not a major suprise the police didnt notice though they dont seem that clued up, i had a old nissan micra once and stuck a 24v turbo sticker on the back, got pulled over and the police officer put on the producer micra 24v turbo

Tue Jul 10, 2012 3:21 pm

When did i say welded diff's were engineering? engineering a car tailored to someones preferences could include the usage of a welded diff

If the scaremongering from 'authorities on the subject' here are to believed it's amazing that the po-po got it back to the pound.

Shouldn't they be on fire in a playgroup after the diff raped them off the road for backing off in a corner?

Ah yeah - advanced drivers, innit...
