Blackline ATB diff - any good?

[yorkshire_spam]

I'm contemplating a Blackline ATB diff for the Spitfire 1500 (fast road spec engine) - wondering if anyone has any experience of this unit? Positive or negative? 

Can't afford a "real" LSD like a quaife, but the Chinese ATBs are in the price range where I can maybe afford it.

Cheers, Sam

Found this earlier discussion.... https://www.clubtriumph.co.uk/forums/topic/7574-blackline-atb-differential/

Anyone reached any conclusions based on usage?

Not myself, but Nigel Clarke on another forum has recently commented he is very pleased with the one in his 2.5 GT6.

I have 2 REAL Quaifes and a Blackline not yet fitted. The Blackline looks as nicely made as the Quaife. A LOT of these have been sold and I have not actually read a complaint.

Thanks for the feedback chaps!

Based on only a few hundred miles use, I am very pleased with the blackline LSD in the 3:63 diff in my 2.5l GT6

Hi Sam, out of interest what are your reasons for contemplating an ATB? My diff is making a bit of noise so I'm wondering about these options myself.

I have one in my Vitesse bought from 2Spec Transmissions.

Seems to work. Drives normally on the road and definitely has more traction, though if you truly lift a wheel it just spins (normal for ATB diff). Main reason for buying it was finding that every one of the 4 diffs I had in stock had some sort of problem with the carrier or cross pin and I fancied something stronger. Done maybe 3k miles and a couple of track days, so still some way to go before I’d consider it proven longevity/reliability wise but signs are entirely positive so far.

Hi Pete, couple of reasons really.

It's pretty much impossible to get a variety of shims to rebuild the centre section of a diff that the LSD replaces - so it would eliminate that issue with the rebuild.

Secondly I do like to enjoy driving the Spitfire in a "enthusiastic" fashion, some extra traction at the rear wheels would be nice.

I have one in my 3.27 GT6 diff. I'm pleased with it.

Done maybe 3000 miles so far. Definitely feel the extra grip but does snap pretty hard if your on the throttle too heavy in the wet 😂

Thanks for the feedback @TimW

Took the plunge and ordered one, I have a spare 3.63 that I'll use it in and at some point swap them over. (Although Spitfire is "back burner" until after the 10CR in the Dolomite)

Ordering a Quaife is taking the plunge. A Blackline is half the price.
