I've been leery of any of the Kumho variants after those pesky "groove of death" issues

Slicks:

- Michelin: For top times. An overkill if you are not racing, or running a Time Trial where your class allows them. I ran a set on my GT3 for two events, and they were sick. Highest grip I have experienced with any car.

- Good Year slicks (250 compound): Very expensive and not as good as the Michelin S7.

- Yokohama: I bought two sets used. Decent grip, but I think they were shot.

- Pirelli. Never ran them. They make sizes for the GT3. The Cup cars guys buy these instead of the Michelin for longer life.

DOT-R:

- Kumho V710: Probably my favorite tire for fast track times, without killing your budget. They have as much grip as the R6 (if not more). Indeed, in some cases they are as fast as the A6. They last forever.

- Hoosier A6: They are the fastest for auto-X. And they are as fast as slicks for two laps at the track. For time trials, this is what I use.

- Hoosier R6: Consistent, lots of grip, they don't last as long as other DOT-R. Your choice for fast times are these or the V710.

- BFG-R1: No experience.


No trailer:

Toyo RA-1. I put 8,000 miles on one set. Good on the street/track/auto-x. Faster as they wear out. Slow when new. No shaving. This tire will be history once the R888 replaces it. Spec Tire on several Racing series, so lots of development goes on them.

I have driven to some events on the A6, V710. I put 1,000 street miles on a set of V710, and around 500 street miles on A6.

Disclaimer: If you get pulled over on the streets by a traffic cop, while driving on any DOT-R tire like Hoosier R6/A6, V710, R1, most likely they will tow your car, as soon as they read "Not Intended for Highway Use" on your tires.
what size khumo 710 do you run?

I ran 245/285 on 9"/11" BBS Mag wheels. They were 0.8 secs faster at a high speed autocross course compared to my 275/335 Toyo RA1 (45 secs lap).

Later I ran 285/315 on my 10"/12" wheels. Even faster times, but after 2 minutes the ABS light will come, and the brakes would get on ice mode, you can't use this for the track.

Right now there is a 305/30R18. I would run 285/305 on 10"/12" for a 996 GT3. For the 997 I would run 10"/12" with the 285/315.

For drivers with skinny front wheels, 245/305 on the 996 and 245/315 on the 997 GT cars.

The V710 fits your driving style, as they love to be drifted. The Hoosier has this on/off behavior that slows you down when off the grip. The V710 has a nice progression of longitudinal and lateral grip. My driving style goes better with the Hoosier.

255/35R18 front and 305/30R18 rear on stock wheels (8.5" /11"). I ran 275/335 RA-1 on the stock wheels, but the car felt softer (and not faster), these same sizes RA-1 on the 10"/12" wheels were a lot better.

scott I've got the yoko Advan 048s pictured on my 993TT and have nothing but good things to say about them as a mixed use tire! I think I could get 15k miles out of the rears.

Whoa really? How many track days in that 15k miles? Their UTQG rating is 60.
