While visiting home in NorCal over Christmas I finally let my brother pilot my 98.5 A4tqm. Used to driving an 88 e30 m3 he quickly noticed that the a4 didn't drop revs while shifting. We theorized that the a4 might benefit from a lightened flywheel. I know that Greedspeed /neuspeed make (or modify) one for the a4 but<br>I have not found any specs on how much (A) the<br>stock flywheel weighs, and (B) how lightened the lightened flywheel is.<p>Anybody have info on weights and other manufacturers????<p>-TIA-

<br>Would you really want a lightened flywheel? True that the engine will rev freer, however, in a car as heavy as an A4, and a car with a turbo, you may not want the RPMs to drop quickly. Plus, if a flywheel is over-lightened, you will suffer driveability problems, especially on an all-wheel drive vehicle.<p>

much of that 'rpm linger' is due to the ecu software.. perhaps audi designed this into the coding to make the car easier to drive smoothly. anyway, a chip might help. anyone experience this after chipping their 1.8t's?
