Hi again, Greg,

At the risk of hijacking rdane's thread, we are certainly more IN agreement with you than not. That is evidenced by our original advice to him as a preferred solution, "we would have a set of soft-compound GoodYear or Hoosier slicks - without question. "

We would not "go backwards" in rim width, however, especially on the rear. In addition to the contact patch deficit, by narrowing the track, in particular in the back of a 911, one invites even greater lateral weight transfer.

You have an excellent point about Cookie Cutters as opposed to Fuchs or BBS when cost and availability are the primary considerations. When lap time is the driving factor however, we would use the lightest/strongest (and widest) wheel we could find. And YES, we too would prefer 15" diameter for this application.

As to the used slicks, it is more a matter of preference (or philosophy), but, for us, if the entire event hinges on three or four quick laps (or runs), we would want the softest compound, freshest rubber we could find. There are very good reasons why those "70% slicks" cost 30% of the new ones! Those first few millimeters of rubber are like gold.

Incidentally, I believe Hoosier has discontinued the R25 and R25A compounds in all the 15" diameters except for Formula Atlantic.

Lastly, thanks for not jumping all over my "one square foot less contact patch" statement - I must have had one too many turkey sandwiches . . .
