tuning,quaife diff for leon cupra mk2

[Al]

My diff has been fitted by a specialist in England who does gearboxes as well as tuning and all sorts of other things to a spare gearbox I bought.

The modified gearbox is now complete after a check/service and with some adjustments, it is now ready to be sent up to be for a straight swap out with my original gearbox along with a new clutch.

If you are going to order a diff, be sure to ask for the fitting kit for it which may or may not the bolts mentioned above.

My gearbox only needed a new seal for completion. With regard to oil type and quantities, I dont know yet, but I will soon.

I expect a gearbox swap to take approx 3 hours which is much better for me than a 1000 mile round trip, night in hotel etc and I have a spare gearbox if I should have any issues

Hello all you guys in England. I want to give you some advice on the LSD. You can go for the Peloquin or the Quaiffe. When ordering the Quaiffe, you need some extra products.
This is what you need for sure, to make it right:

new differential bearings, upgraded bolt kit, end-cover gasket, o-rings for pinion plate studs, and o-rings for shift fork support pins. As for the bolts, you would go for the ARP bolts. Best there are.

If your mechanic is really good at this job, he makes sure that all the bolts are secured with a weld spot. This is what mechanics do in racing and rally to prevent the bolts from shaking loose. Mechanics who are used doin' this installation, knwo exactly how.

Over here in Holland there are only a FEW people who can do this mod right.
The total time is about 10 - 12 hours. That is what makes the job so expensive.

Make sure you get it done by somebody who knows what he is doing. On or Dutch forum there is allready one guy who has big problems with the gearbox because the mechanic was not used to doing this mod. A LSD diff is really the best you can do, but don't cut on the expensive parts and don't cut on the working hours. Get it done right or leave it out of the car ..........

Take a look at the picture below. This will give you some idea how the diff is adjusted. It comes to 0,25 mm or so ........

Guys, could you please advise me on the following.
I have bought the Quaife QDF14R for my car (Seat Leon Cupra, MY2008) O2Q Gearbox, FWD. As I have checked on the Quaife website, I noted that this is not compatible with my car, and the right type would be Quaife QDF16R. They look the same, would they also be the same on the inside. I wrote back to AutoTech America (they sent me the the LSD) and they told me it is identical and will fit my car without any problems. What do you think?
I will also call Quaife on Monday to get to the bottom of this, just thought any of you had dealt with this before.
