If you want to enjoy a mini, and are running normally aspirated, go with a 3.44... you'll not regret it..
And 4k @ 70's not that bad

Yes if you like running @ 6.5K rpm constantly...
Its a good diff to go for if you have an engine with plenty of torque. Good for over 90mph in 3rd and at least 120mph in 4th
but the actual fact is you wont get there...
Example being the late coopers which have a 2.7 diff and they are absolutely hopeless...
2.9's should be reserved for the economy seeker, motorway driver and extreem Force induction motors, which have spades full of low for torque to pull the diff round..
at worst go for a 3.1, which will be 70 @ less than 4k.
But I stand by that the 3.44 is the best diff for a normally aspirated mini, unless it's a massive stroker.

That gearbox died and I put a box on with a 3.1 diff. It's so much more fun. much better in town, accelerates quicker. The downside is a few more revs on the motorway, but it overtakes much more easily now.

Acceleration in first was a bit poorer than the 3.2 ill agree, but nothing too noticeable.
The thing i find about the 2.9 is its very versatile, especially 3rd as you can either cruise at 30 or rake it at 90+. Like an automatic :tongue:
IIRC the Mini 25 had a 2.9, and that sucked. That was my mates first mini, and we both had 998's at 17. I would rape it bottom end, but that was it. once he had his momentum... vroom!
