Greg:
WHile the $ is pouring out ... pick up a pyrometer. Especially, if you are going to continue to run slicks on the 930. If you want, we can share some of the tire temps / settings we use at the tracks you'll run. Have to factor in suspension settings, comparative weights of cars (RSR and 930), etc... might be a jump off point at least. We used to run hoosiers but have gone back to goodyears. Even using the pyrometer, we'll chase tire pressures throughout the day as weather, track, wear, oil, AF, etc.... changes track conditions. Can't say that we've run slicks when it is freezing but have run them when it is raining  YMMV, etc... Jase

Why does everyone want to make slicks out to be the big, bad tires?
What are you guys afraid of? Seriously, we have run the cup car, the 914 and the RUF on slicks March through Dec at events without problem. If you think about it the slicks should work better than RA's. Softer compound and more rubber on the pavement=more friction=more heat and more stick. If the 914 were running I'd be out there on slicks. Just up the starting pressure and slide it around (gently!) the first few laps to get heat in them. And yes I'll get in the right seat with anyone with slicks next weekend....

.....I need to get a new set of tires for the 3/12 Summit Point DE. I want to get a set of Hoosier slicks - Does anyone know who has the best price on them? I hear they grip a LOT better than RA-1s, and I hear that will really help me learn the car in my first few DEs.

make sure you pay extra for the heat cycled ones... they will almost do the driving for you

OK. I came on a little stong there. Sorry. I've now had time to calm down.
 I hear from a lot of people, most of whom have never driven on slicks, about how twitchy they are, how until you warm them up they have no grip. The reality is that slicks have more grip out of the box than RA's just like RA's have more grip than regular street tires. This is why they are so cool to drive on. This allows me to take turns faster and generally attack the course more aggressively than with other tires. They are NOT good for anyone trying to hone their driving skills or someone doing car set up because they cover a myriad of mistakes that will come back to haunt you. They are also not great in the wet. (You'll notice our cars tend to sit in the trailer when it's raining.) Oh, and they are not good in the brake zone of turn 1 at VIR on the first lap. Gotta do something about the sand down there... 8) Obviously this is a hot button for me along with the "big, bad car" syndrome. All cars are basically the same. As they get tweaked things just happen faster. They are only big, bad cars if you're not paying attention to what the car is telling you and reacting in an appropriate manner (as in quick enough and gently enough). I'll still ride right seat with anyone with slicks next weekend...
