Drive Train getting loose from Lap Days

[swbca]

I rarely see A4's on the track compared to S4's .

I have had my 2014 A4 at the track for about 10 days since I bought it a year ago. I use E85 with APR Stage 1 Tuning so it been bumped from 220hp to around 300. After 2 days at Road America last month I first noticed more play in the drive train while driving. Its a Tipronic Transmision. When I manually roll the car back and forth when its in PARK, it rolls about 2 inches with a sharp (not rubbery) bounce at each end. Compared to other Audis with more mileage, they roll less distance and the movement is more like elasticity than like free play. ( hard to describe )

The mileage is 33,000

So has anyone had experience with a loosening drive train to guess what might be changing ? CV Joints, drive shafts, gear boxes ?

You should probably ask this question in the a4 section? Drive trains being completely different, and all.

Sounds like motor mounts. The mounts in my A5 failed and started leaking after some instances of hard driving. 2.0t and 3.0t motor mounts are the same.
