911mhawk

I have 63k on mine and put my other wheels on because I thought there may have been a balance issue causing very slight vibration in steering wheel.
Am going to throw it up and look at the suspension pieces to check play but am curious who has done theirs, and what improved feel options some may have gone to.
In my 6t, I redid everything with Tarett, ERP in monoball all around but that's more a track car.
Has anyone here upgraded their 991.1 with GT3 or Cup LCAs and Tie/Toe arms? How was the improvement?

Am I correct that the LCAs are the same for all 996/997 and 991?
If so, I may just swap my Tarett with fresh bolts and bushings when I install the Cup parts I have sitting on the shelf for my turbo.

Thanks
