Got any big plans.

I'm just improving the car (IMG:http://www.frrax.com/rrforum/style_emoticons/default/biggrin.gif)

And the "plan" is to NOT put it off until last minute...

What's up everyones sleeve?

FWIW, Dan Popp told me he thinks the new Hoosiers are slightly faster than the new Kumhos, but not by much, and probably not quite as fast as a fresh set of the old Hoosiers. He also said that the new Hoosiers take a lot more pressure than the old ones (many people probably running them too soft), and that he hasn't seen anyone cord the center of an A3S04 yet.

I've found that I'm fastest with the A3S04s inflated beyond the point where they feel or wear the best. In other words, when I think they are overinflated, they are about right (IMG:http://www.frrax.com/rrforum/style_emoticons/default/smile.gif) They seem to be wearing like iron though, even on some very old and abrasive concrete (many decades of weathering with little traffic to wear it smooth) and three events in a row on a very fast rough course on extremely grippy asphalt.

The main downside of the A3S04s in my opinion is that it's hard to get them hot enough on a low grip surface. At one event a few months ago on slick, sandy asphalt, Rob's tire temps were running over 10* higher than mine, and picking up a lot more debris in the grid. He was running 275-17 Victoracers and I was running 275-16 A3S04s. Both sets are about the same age and have comparable runs on them.

FWIW, I don't think Popp has any trouble getting a set of tires up to temperature quickly. It's amazing that they don't melt on the first turn.

For me though, there isn't much choice. The only current production 275/45-16 is the Hoosier x3S04. While I could use Kumho 265s on my 10" rims, I'm not inclined to do so - the Hoosiers fit "just right".
