Not suitable for cosworth models,so presume that means only available for push in shafts?

Even so that's not a bad price though, particularly if you already have a dif with push in shafts given the cost and hassle of changing to a Standard LSD with bolt on shatfs.

I hadn't thought of it that way.

Ugg10 - 19/10/18 at 09:37 AM

These are similar to the Quaife ATB's. Helical not plate LSD.

Good price though, please add comments on how you get on with it.

I was talking to a chap at burtons earlier this year and quaife aren't very happy with the blacklines very close similarity to their diff. Hence the price drop on the quaife.

Looks good.

Anybody recommend some one around the Peterborough / Lincolnshire area to install it with new bearings ?

Now that shows the power of competition. They have had the market in the UK for a very long time

St Neots any good? A1gearboxes have always given me excellent service. Not the cheapest but very good, no connection other than a very satisfied customer

As an engineer this statement -

"We recommend that the axle oil is changed after the first 500 miles as initially they can create swarf - this is normal and will reduce with use."

Makes me wonder as no precision engineered component should create swarf and I take from this that you get what you pay for. Lets hope you brand new bearings fitted when installing the diff are not destroyed whilst the swarf reduces with use.

I find that most odd.

I'd rather buy a quaife at the reduced price than the blackline, doesnt make sense to me for the small difference.

Obviously you haven't done the first service on any cars that have magnetic sump plugs?

I would / may buy the quaife over the blackline at the the more competitive price but I would try the blackline given some reasonable feedback at the old price.

St Neots isn’t that far, thanks.

This is very common practice. I install large gearboxes on projects at work from the likes of brevini and the first use oil change is standard routine

Obviously!

Even when modern jet engines come back from overhaul you can get "shop swarf" when you pull the chip detectors for the first couple of inspections.

However in this case the flip side is that quaife do not stipulate to do it which is quite telling.

Also blackline has a 12 month warranty vs a lifetime on the quaife. Chinese made vs British made.

This comment always fascinates me. From what i can tell you have worked in an international aviation industry for years. People from other countries can make stuff as well and sometimes better than the UK the problem always is the price point. I have seen some shoddy machining from reputable UK firms and China. I have just completed a new process plant install. The tender from some UK companies would make you cry. Simple things like weld details and qc packs.

Just saying pay your money test the item and don't always follow the UK made is best hype. We have great engineers so does alot of countries.

sdh2903 - 20/10/18 at 11:11 AM

Femster. If you read my post I never suggested that the Chinese couldn't make anything to a high standard. I was merely highlighting the differences. Am fully aware of quality control issues in every corner of the globe and on our own doorstep.

However in this case, for a 70 pound difference you have the choice of an unknown brand made several thousands of miles away that only have the confidence to give a 12 month warranty on their product. Are spare parts available? Where from?

Or a company that has an excellent reputation who supply their products to several oem manufacturers and have the confidence to give their product a lifetime warranty.

Merely an opinion of course and have no axe to grind.

Okay...
Been out a few times on my favourite known Islands, plus negative camber hairpins and assorted launches..
Initial verdict is... I love it..
Launch is improved.. 0-60 faster!
Negative camber uphill hairpins come in smooth and faster with a more powerful exit.
Drifts on Islands are now faster and feel well planted.
Snaking onto fast main roads is so more reduced and the feel of the lsd gives a very very nice point and squirt feel.
This lsd does feel and behave different to an open diff and I really need to be cautious till I get the full feel of it..
Also I think the lightweight of the car and this lsd are not a bad match and comes into its own when driving aggressive.

Would I recommend this lsd ??
Yes.. I highly recommend this unit even after a handful of drives..

I don't expect any problems with this diff because its fitted to such a light car .. (I will update this in the future).

I could be talking utter bo**cks but hope that peeps find this useful ..
