I think the biggest problem with our cars on the track is understeer. The key to mitigating that understeer is more grip on the front. I would worry that going up to a 275 in the back without really making massive grip improvements on the front would do more harm than good. I'm not a pro, but that's just my sense.
I did 3º negative camber on the front with 10mm wider front and back. I had substantially less understeer and way better turn in.
