How much would you pay for a modern tech 15" 60 series performance streetable tire?

I don't auto-cross, cuz the closest track is 3 hours away.
But I like to powerslide nearly every corner I come to, below 40 mph. I can do that because of the 275/60-15 BFG or Cooper no-stick tires. Since I'm forever turning the car with the rear end, I have found 235/60-14s adequate up front.
To get the braking I needed. I put it in the back tires. I run theKH 4 pistons up front with performance pads. And I run 10x2s out back with zero proportioning. Since this is a streeter, and the speed limit is 65, I'm in pretty good shape.
So yeah, I'd be interested in sticky 295/60-15s/325/50-15s and sticky 235/60-14s/245/50-15s; which I have custom wheels for.
But there are several things I come against that with,namely; A) I bought new spare tires several years ago. and B) I'll be 64 on Sunday, so how many more years am I gonna drive like an idiot?, and C) I'm a streeter,running under 65 mph, and D) I have a hot 367 that smokes anything to 65, and it only takes around 5 seconds.
But if I was in some type of competition, then $800 to 1000/4 would seem reasonable to me.
But, I remember these F1s I once had, man those things stuck pretty good. But the only lasted about a month, on city streets.That mighta-bin 400 or so miles! Then they were bald all the way across the threads. Slicker than slick. It was a lot of fun while it lasted ,tho
