Can i just ask which lightened flywheel you used?

And how heavy the stock one is.

I have a 2.5 manual and i'm thinking of either a screamer NA 7500 rmp wagon or a t6 swapped boosty-beasty.

If the former lighter flywheel is a must.

Oh, and did you notice on the 2.5 the flywheel seems well judged for rev-matching? I find as a i shift gear the revs have fallen almost exactly to the next ratio when i bring the clutch up. Didn't notice it in my 940 on the stock DMF.

I only drove the 2.5 car about 40 miles, rough idle, didn't reach temperature and was totally gutless, so no real experience of a good one, went with a Classicswede 5kg (I think) flywheel, about 3kg less than standard, wanted to loose the dmf whilst doing the conversion so figured it made sense to upgrade at the same time

The lower axle ratio on the 2.5 I guess this was a vain attempt to compensate for the smaller engine's lack of torque. I've owned all four combinations - 2.5 and 3.0, manual and auto. With the 2.5's I was always conscious of it being a smaller engine having to work a lot harder. The 3.0 is the engine this car should have - the extra 0.5 litre really does make a noticeable difference in driveability.
Turns out the car is fitted with a 3.9 rather than a 4.1,not the end of the world but a bit disappointing

Probably slightly slower on acceleration but better on economy and cruising. Think i have the 3.54:1 axle in mine but certainly wouldn't complain if it was a 3.31:1 - better economy!
