yorkshire_spam Posted July 27, 2022 Share Posted July 27, 2022 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.

Clive Posted July 27, 2022 Share Posted July 27, 2022 Not myself, but Nigel Clarke on another forum has recently commented he is very pleased with the one in his 2.5 GT6. 1 Quote Link to comment Share on other sites More sharing options...
Gt6s Posted July 27, 2022 Share Posted July 27, 2022 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. 1 Quote Link to comment Share on other sites More sharing options...

iani Posted July 27, 2022 Share Posted July 27, 2022 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 1 Quote Link to comment Share on other sites More sharing options...

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.

Nick Jones Posted July 27, 2022 Share Posted July 27, 2022 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.

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.

TimW Posted August 1, 2022 Share Posted August 1, 2022 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 😂 1 Quote Link to comment Share on other sites More sharing options...

yorkshire_spam Posted August 2, 2022 Author Share Posted August 2, 2022 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) 3 Quote Link to comment Share on other sites More sharing options...
