Nice updates  :smiley:

My rack will need replacing at some point as it knocks also, so I'll probably do the same as yours!

LSDs are hard to get right on FWD. They're great in the dry but in the wet, they can be a hinderance as you don't want both wheels spinning mid corner!  I reckon the Wavetrac with the MK6 XDS ABS ECU is probably the best every day package.  The Wavetrac combines advantages of torque biasing and plate diffs.  Normal ATB diffs like Quaife and Peloquins still need a minimum of 5% traction on one wheel, otherwise one wheel will still spin like an open diff.  They're both useless in snow and ice.  The Wavetrac offers a bit of traction in zero load conditions, but will never match a full plate diff.  Plate diffs can be a pain in the neck in a road car.  Noisy and require maintenance to replace worn plates, but a road spec Gripper diff is apparently the best of them.

Anyway, XDS + Wavetrac is the way forward  :happy2:  The MK5's XDS only works up 40ish mph and is easily overwhelmed by remap/BT torque.  The MK6 XDS is full time at any speed (iirc) and is way more effective.
Black Edition 30 with manually selected cogs, a beefier clutch, some extra boost and them Whiteline thingies, otherwise standard.

I have the experience of the XDS on my wife's Golf. It works beautifully on roundabouts but on fast corners I don't like it that much. It cuts too much the power, but the car doesn't understeer, to be fair. The mk5 TC doesn't have XDS available, as far as I know it just brakes both wheels when it detects wheel slip. XDS will only brake the wheel on the inside of the curve to make the car turn better.

About the LSD, well, I don't have snow or ice where I live so I never felt any issue with my ATB LSD. It works pretty well. If I ever need it to work with one wheel up it the air I can always apply a bit of brake pressure. I don't remember ever needing to do that trick, though. I know the Wavetrac LSD is better but it would cost me almost double the price of what I paid for my MFactory one. :innocent:

I've solved the wheel arch tyre rubbing with a bit of roll fender. These tyres grip better than the Federal on dry roads too. I'm having more fun being able to corner faster now. :driver:
