Tire feathering/ Alignment specs?
Earlier this year I got a set of Bridgestone Portenza RE-11s & I love them. Did a couple of autoXes then parked it for ZDayZ. Right before ZDayZ I got an alignment because I had no idea where my alignment specs were & was scared to ruin the tires on that long of a drive.
Right after the new alignment I drove 1,200+ miles of hard driving for ZDayZ. The tires performed awesome. Then I autoXed it for the first time on the new alignment & it did awesome. However the second time I autoXed the new alignment I noticed at the end of the day my front tires feathered a little. Now Im not driving my Z till I get my alignment redone. Here are my before and after specs:
Before
Left Front: Right Front:
Camber -1.4* Camber -2.3*
Caster 7.8* Caster 8.5*
Toe 0.09 Toe 0.19
Left Rear: Right Rear:
Camber -1.4* Camber -1.4*
Toe 0.26* Toe 0.30*
Current
Left Front: Right Front:
Camber -2.5* Camber -2.5*
Caster 7.8* Caster 8.5*
Toe 0.02 Toe 0.01
Left Rear: Right Rear:
Camber -1.9* Camber -1.9*
Toe 0.07* Toe 0.14*
If anyone could provide input on improved specs I would appriciate it.

im at a tech at firestone, and let me tell you that's a pretty much perfect alignment - however did you ask for the out of spec increased negative camber in the front? front camber range is -1.3 to 0.2. uneven camber is really what eats tires so at least you're dead even on both sides, however the normal camber range already gives a tire feathering problem, so doubling it like you have will make it take turns great but wear even more. also be weary of those potenzas, they're the best performance tire we have but they wear out fast, and ive seen quite a few come back cupped

I did ask for increased neg specs. My last tires were on the car when I got it and thet were BFG SuperSport A/S and the original alignment was good on those, so I thought the sticker tire would require more agresive camber.

Just back it down to around 2 and check your results. The needing of camber is dependant on a lot of things , you will probably need more as you become a faster driver
