I have a series 2 xsi 16v can you change the diff with the gearbox insitu ?
done it a few times on the GTI6 its tight and you have to remove 2 out of the 3 engine mounts

Are you changing the diff for a LSD? Its a really nice upgrade on a 306 so i highly recommend it! The quaife ones dont require any maintenance either but only work when both wheels are on the ground. Youd need a plated diff for more gains but then it requires maintenance, so its not really for every day use.
