Yesterday I istalled Quaife ATB. It is my best upgrade. The car goes 300% better in corner, has better driveability and understeer is out now. Lancer Evo friend told me the cars feeling is too close to Evo.

One would assume it's the front diff. IIRC, Quaife dont do a centre diff version of their ATB and I would gather from the desctiption of improvement that it was the front one he fitted. Haven't heard of anyone fitting a rear quaife on a scoob yet, but i am sure someone may have, being that it is available to buy.
If you want a helical centre diff, Modena do them, apparently they are very good on tarmac.

Andy,
I think when moray says helical he is referring to the gearing inside the quaife atb.
According to the literature quaife use the fact that you can drive a gear with a helical or worm gear, but you cant send drive back to the worm gear from the other. Either way I am not going to pretend I know anything about the complexities of these because I cant get detailed literature on how they really work so am not going to try to guess. One things for sure si that centre diffs are not that easy to understand.
I presume when he says helical centre he means a centre diff with this kind of set up rather than a standard viscous centre or a dccd.

Andy,
I mean a helical gearing centre diff, guess worm gear would be more explicit, but mitsubishi etc refer to ATB or TorSen syle limited slip differential unit using the one way properties of worm gears as helical gear diffs, so I figured it might be acceptible.

Moray

No, I was unaware of the type of diff Modena offer for the Subaru and I was wondering if you meant another new design. I know what you mean now 
cheers
