Actually, I was out with Nat having dinner, drinks and generally painting the town whatever colour we decided on earlier. Have now just got back home, it being 4:30am, and am going to sleep until 7 so I can be bright and breezy for dyno day. Nat on the other hand will be sleeping till 2 and I'm very jealous.

Good night.

Oh and ps.. yes, you can have a run in the beast

No, had Kevin at Birds Garages to do it for me. It's not actually that tricky, although you need some specialist tools to make the job easier. And obviously a lift.

True. But the LSD does also bring big benefits in off-line acceleration too

I didn't think anyone was worried about breaking bearings?! In the fifth picture of my post, the diff on the right shows the crown wheel attached by bolts. The new-style welded diffs have no bolts as the crown wheel is welded directly to the diff casing. That is the bit that requires machining off.. Does that answer your question?

No, people were really worried about breaking something, that could not be sourced through BMW, during the removal of the open dif out of the housing and putting the new one in. I thought it was a set of bearings but I'm not really sure.

Very educational post - Thanks...

I cannot help but wonder why such a price difference between Mini and BMW I mean its over a grand

Oli · 12-08-2007, 07:28 AM

Didnt the 'old' Mini Cooper S have the LSD as standard?

£115 for a diff on a Mini is mega cheap, and that's because it is installed on the assembly line. The £1200 for the Quaife diff on the BMW is because it's an aftermarket part, and replaces the BMW unit. That also includes the labour cost for installation too (three to four hours), and VAT.

I think you're right - the LSD came with the Chilli pack on the 'old' Cooper S

I really want this unit installed in my car as i do feel that first and sometimes 2nd gear is wasted due to the DSC!

Look forward to seeing you tomorrow buddy, and i want a ride in that beast now!!

So Mr Fandango what did you think then? Night and day difference huh? I really think you need to get one, especially after the remap, given the way you like to 'fully use' the power at your disposal !!!

G33 · 12-09-2007, 08:04 PM

where did you get this done mate?

E92Fan · 12-09-2007, 08:11 PM

Birds Garages, Uxbridge..

they're the UK dealer for Quaife and Hartge

Hotcoupe · 12-10-2007, 02:16 AM

Good stuff Tony and very informative.

The Bird's site is an interesting read,I'll skip on the LSD mainly due to cost,but there was something that caught my eye,but it will have to wait until after Xmas now.

Evil Diesel · 12-10-2007, 03:00 AM

Good write up. Its good to read about a performance mod that doesn't involve adding horses.

scottc · 12-10-2007, 04:16 AM

I drove Tony's car on Sat and it was excellent, the amount of traction was awesome and it felt totally planted even with it pi**ing down

I then went out with James and it was very different, if James had the diff that car would be so much quicker as it will be able to put the power down (not that it wasnt bloody quick

)

I think if you have a 335i put aside £2k and get the map and diff and you will love it

nagge · 12-10-2007, 04:30 AM

How about driving in snow with the LSD? Will it get all tail happy?
Damn this sounds too good to be true

Tony it was awesome, when i and evil were following you on that slip road, we just had that blinking light flashing and the brakes being applied and you roared off cuz you just had so much traction.

When you took me out in it i was amazed with how fast and how easy it was to ''NAIL'' it round a soaking wet roundabout with no DTC/DSC intrusion

Simply Unbelieveable

Good review E92, one questions, does it make the front try to push straight on when cornering?

When i went out in it i didnt notice that at all. It not a rear geometry change, its just the diff. It improves the handling tenfold. The car should have come from the factory like this. It gives you much more confidence to keep the throtte buried out of bends!

Depending on the amount/severity of slip, you can sometimes feel a slight reluctance to turn in on sharp corners, which feels a little like understeer : which I can imagine was why creepy coupe asked that. We know there is no geometry change, but that is one effect of an LSD.

One other question, is there any increase in mecanical noise from the diff - as you state that the diff uses gearing, rather than a shear properties/hydraulic application ?

dxb335d · 12-10-2007, 07:20 AM

In that old skool type singing voice ''anything Carlos can say, Dave can say it better''

Serjames · 12-10-2007, 07:34 AM

technically Dave, you're spot on there is increased noise.

But with the 335i you can't hear it at all !

On a front wheeler, maybe, but with out engine and exhaust not a peep.

Exactly my question Dave, my understanding of LSD in motorsport applications is that push on was a real trait, so I wondered if a road car version was more user friendly.
