Well I've had these on the car for the last two seasons and the fronts haven't even been used much and I daily drive the car...the rear that was 275/30/19 is completely used up from ripping it up on the RB turbos past 6 months
275s can't hold it traction on high boost...with 295s I'm hoping they'll do a bit better on the street...for track days I have a dedicated Kosei 17" MickeyThompson 275/40/17 setup for the rear but that can't be street driven when rain surprises you, pretty scary when its wet actually and you don't even have to be going to fast or cornering
Vredesteins have been MUCH better on my car than even the Goodyear Eagle F1 DS that I had, I won't even mention the General Exclaims lol
