Oh boy.....
I'll just post the info before the search police gets here:
REARS: 345/35R-19 Bridgestone Potenza RE050A Scuderia
FRONTS: 265/40ZR-18 Bridgestone Potenza RE050A N1(Porsche) XL
Don't get just the rears. Change all four if you're still running the Good Years.
Nothing only works if you're EP, and he no longer has his GT"Bridgestones or nothing"
Yes, the A6 isn't made anymore for the rears.
