Parts needed to install a LSD on a DSG
Shoduchi:
Fitting the LSD is basically the same as a manual car. The difficult part is to open and close the DSG correctly. I'd say it's difficult because I'm no mechanic.

Ball ache. You have to drill the rivets out.

And in my experience, not worth the cost. Yeah you get a little more traction out of corners but nothing that blows your skirt up.
High power/torque needs 4WD. Period.
If you really must get a FWD diff, I would also fit the equal length driveshafts from the BKD diesel engine.
Having a long and a short shaft with an LSD creates havoc on bumpy country roads under hard load, especially with cambered roads and lowered suspension where bump steer also creates it's own mess. And the car doesn't want to turn-in as keenly with a diff either. And the diff can actually increase understeer unless you apply throttle in the corners to engage it, or trail brake.
But these drawbacks are what no one ever tells you. It's all sales, sales, marketing, hype and exaggerated benefits.
The Haldex FWD diff in the Clubsport S is way better than a torsen diff, but not the easiest thing to integrate into a MK5 ecosystem.
Realistically, you're in for 2.5-3K to fit a diff if you factor in a 'whilst you're in there Helix clutch' and a bearing/syncro refresh, with labour. Just the 1st to 2nd syncro hub is £200ish on its own. You could buy and fit an S3 4WD setup for that, or less. And even then the Gen4 Haldex isn't all that :grin:
The Haldex on the MK7 is waaaaaaay more responsive/proactive, and the newer system on the MK8 (can't remember the brand) is even better still.
So in other words, don't sink big dollar into mods that only offer minimal gains :happy2:
It's actually faster point to point, to run less boost and leave the rest of the car alone. And cheaper :grin:

My stock differential was sent to a CNC shop. They also fitted the new LSD with the provided screws and it looked just like stock in the end.

For fun driving I still prefer my FWD to a AWD car. I believe the 8R with torque vectoring and the possibility to send more than 50% of the torque to rear axle can be tuned to be a lot of fun to drive too. Stock vs stock all car journalists say the 8 GTI CS is more fun to drive than the 8R...
With a LSD you have to learn how to corner, but if you do it well you get the car to corner faster. I think I spent around 2000€ with this upgrade because a DSG just needs a tune to handle more torque.
