A Better 305x30x20 Tire?

I'm currently running PS4s in the front and rear (275x30x20f, 305x30x20r) and they are great and all for the 10k or so I get out of them but with the upgrades and now custom tuning...they're just not enough for some "spirited" driving.

I can break loose in 3rd-4th shifts at this point which is not fun.

My PSI is a little high I know (35-36) but I don't wanna mess up the brand new BBS'.

My camber is at 1.7F and 2.0R (stock). I would go with less camber in the rear for more contact patch planting but I would probably rub at that point...plus this is stock, so I want to keep it this way.

Are Pilot Sport CUP 2s going to be worth my time? Maybe P Zero Corsas?

Side note, this engine is ridiculous. I love it here.

That tire pressure is too high to get grip on wide tires, middles will wear fast too.

Try 32PSI warm, then try 30PSI warm. I see you're rolling on 20s and concerned to ding your lips. Hard trade off...

More worried about them bending but yeah, that too.
