Has anyone put the dinan 3.45 gears in their 550i. The stock gearing is kinda tall and i would think the dinan gears would provide a noticable seat of the pants difference. I know that they are expensive but it would be nice feeling that torque multiplication and getting up into the power band quicker.

Also, has anyone tried the UUC short shifter???

Would be interested in feedback on both

thanks
