Lsd options

[geeeman]

I have 7inch open diff (sierra)

Whats the opinions on Tracsport lsd vs Gripper lsd?

Car is road and trackdays

What have you got at the moment?

I’ve had a Tracsport for almost three years (& about 15,000 miles) & I’m very pleased with it. It’s quiet, durable & effective.

It does provide more grip & traction than my previous Titan, which meant that the car was reluctant to oversteer when I initially fitted the Tracsport, but fitting a softer front anti roll bar has restored the balance of grip & the car feels really good now.

I have a BMW diff, but they’re available for the Sierra diff too. I’ve no experience with the Gripper.

If your going from an open diff to LSD , then any brand and type will be an Improvement. If it is for road and occasional trackdays then the Quaife ATB is a good all-rounder and a fit an forget solution. But if you want a plate diff, then be prepared to overhaul them regularly if you are doing road mileages. The Titan was designed and set up for the Caterham and is factory fitted for that reason, but the carbon plate version was a bit of a disaster on road cars. The Sierra version is normally sintered plates and is more durable and my personal favourite (just ideally matched to the Caterhams weight and handling) but others I suspect are just as good, particularly if you are not racing it.

I’ve been trying to keep up with the LSD discussions on Blatchat and as far as I understand the later BMW Titan diffs are sintered and significantly more robust than the carbon plates. More info on diffs here:

thanks not keen on ATB (have had that in a couple of cars)

want a plated type.
tracsport say theirs doesnt need rebuilding, unlike other plated LSDs. not sure if thats the case

I have a tracsport diff in my 420R.

After 18 months of both road & track usage, I changed the oil - it was like new! This is in complete contrast to the black gunge that came out of my Titan carbon-plated LSD. It's also much quieter than the Titan ever was.

sounds like tracsport it is then!

Another vote for the Tracsport Diff, fitted it almost 2 years ago and it's been superb, a massive improvement over the Titan LSD which fell apart (pictures here)
