so which axles did you use? The 2.7 axles do not bolt up to this transmission?

Anyone know if the Audi transmissions are offered from the factory with an LSD option?

I used the 2.7 axles for the swap. The Audi transmission flange uses 10mm bolts, whereas 2.7 use 8mm. You can see in the pictures, I pulled out a flange.

I was actually doing research about before the swap. Some people retrofitted lsds from other Audis, and there are aftermarket companies that make lsds that fit in the a4 transmission.

That was the actual research I was doing! Ultimately, it boiled down to time as I wanted to throw the audi tranny in the car and get going.

So the Boxster S uses 10x50mm bolts
The 1.8 A4 FWD axle bolts are 10x48mm 12mm triple square head bolts

So- the bolts will work and screw in.

I can take measurements of the axles. If the audi axle pattern will work with the Boxster S cv joint pattern, then this will get interesting. There are 6 holes, and the bolts will thread.

It wouldn't surprise me as Porsche and Audi share some parts!

Drudging up an old thread here. Did we ever determine if the audi axle and pattern matches the 986S?
