Replacing diff

Maybe someone should point out that the TS has a 168k diff according to the ETK?

It's definately not a 1:1 swap, maybe it can fit with some extra work, maybe not.

Video of issue, try and put any acceleration on the car and you get a horrible graunching noise and jerking of road wheels which eventually causes DTC, ABS and traction control lights on
Turn off DTC and its drivable with normal acceleration but sounds like something is knocking underneath????

Another question on the diff....

Ratios......

The one in my 2.2 is a 3:45 I've found a 2.5 with 3:23 so does that mean it'll be longer in the gears tban a 3:45?
If so a 3.0 diff seems a better bet with roughly the same ratio and loads on eBay at the moment

Sorry to hi-jack, just want to simply add some knowledge to my mind bank.

What are the benefits of adding something like a quaife lsd to a 3.0i?
