LSD talk. Wavetrac vs quaife vs mfactory vs peloquin.......thoughts/experiences?

[bennjamin]

hi everyone.

This is aimed at my golf GTi mkv - but is relevant to most cars in this forum. So here it is.

LSD's. Looking for advice / experience from LOCAL AUSSIES that have them , have imported them or had installed etc.

Wavetrac and quaife are quite similar in price and operation.
The peolquin is slightly cheaper and often comes with a bolt set and bearings for the same price as the above units.
The mfactory unit - I just found on ebay. Having dealt with mfactory LSDs in hondas before there are no complaints. Considerably cheaper.

Anyway , who here in Oz has had one of the above units installed ? Hows it fairing ?
How much does/has it effected your driving ?
Roughly how much did it cost to get installed

And , any hook ups on a good priced site/s to get from?

etc etc


thanks for any thoughts

Hmmm, looks like not many people go down this path?
I'm currently investigating LSD options (for my DSG gearbox)

We have used Peloquin, Quaife, and have customers with Wavetrac's as well.

Depends on what you are after, all three of these (and the mfactory one) a torque biasing, which are OK & improve grip a bit. If you want them for track use, skip torque biasing & go straight to a plate differential - do it once - do it properly

[Martin]

Thanks Guy

Not much point spending a lot of money on torque biasing then...

Is there a plate differential unit available for the VW DSG?
And is it ok for normal street usage?

[Guy_H]

Hey Martin, there is, but there are several variations on the diff centre itself. We can work around that if we have donor parts!

If you are ever in Brisbane, you need to drive our new MK6 GTI stage 3+ DSG - It has a VWR diff in it (plate) and its perfectly mannered on the street. Took about 1000km's for the plates to bed in.

The VWR differentials are just on $3000, but personally they are 10 x better than a TBD.

What do you mean by this ?

[Martin]

I will be in QLD late March - sounds like another item to add to my "to do list"
(When the time comes, we could just pull mine out and put it on the bench)
Love the VWR gear - Thanks Guy!

Bug_racer:
He means the plate differentials are much more effective than torque biasing
From what I've read torque biasing is helpful up to a certain point...
(I guess you get what you pay for)

[Guy_H]

What do you mean by this ?

Exactly as I said 10 x better.

No loss of traction even with wheel lift, no bind / unbind mid corner when the TBD releases. On a tight track, its about 1.5 seconds quicker per 60 second lap.

You won't find a TBD used in any form of serious motorsport in FWD cars - even Mfactory make plate diffs for the Honda's for track use, but they don't make one for the VW's unfortunately.

I have spent a lot of time working with the APR crew on the setup & ramp angles on the two way differentials, and the single one we use for the street versions as well. And just had a week at Volkswagen Racing's HQ in the UK, and a big topic of discussion was diff setup, Carbon plates vs Metal plates, and how aggressive we can go on the street and still be able to park it in a shopping centre - All very interesting.

[Guy_H]

P.S. - Martin, give us a call when you get a date & take it for a spin - once you have experienced the grip of these things you will be a convert. Even have a version in our Polo GTI as well & it's an entirely different vehicle!

Gavin is interested...

Gavin is no longer interested

[Guy_H]

Yep, only downside is the price.

I wish VW would follow some French FWD specialists & start to offer mechanical differentials as standard or options.

according to This , mfactory does make a "metal plate" LSD in 3 forms. I would guess this means "clutch pack" ? Care to comment on this - $882.41 is a tad cheaper than $3k

[Martin]

They are for the manual transmission
The manual transmission has more and cheaper (all below $1k) options from all these manufacturers (Peolquin, Quaife, Wavetrac, etc)

Switch to a DSG discussion and the entry price for bias torque units is $1,500~$1,600 USD
Then you have to get it shipped to Oz, $500? (If you're familiar with USA/CAN shipping rates)
Then you still need to get it fitted

While I love my DSG transmission,
I can't help thinking I should get a cheaper manual car for the track
It would give me more/cheaper options

Good observation and sorry I forgot the latter of this thread was about DSG boxes not manual.

A point though , is that the DSG equivalent LSD is not much more expensive than the manual equivalent. So the $3k quoted before if its for. DSG would be a similar price for a manual box

bennjamin,

We worked with mfactory for 6 months, we even sent differential centers to their HQ in Asia - believe me, they have no plate VW diff - regardless of what you read on the internet.

Here is a challenge for you - see if you can order one (even a manual one) if you can get a plate version from Mfactory, i'll buy it off you for double what you paid!
