Talk to Michelin.
If it applies, from Tirerack : "Tire manufacturers' warranties typically cover cracking for a period of 4 years from the date the tire was purchased (receipt for the new tires or in-service date of the vehicle required) or four years from the date the tire was manufactured." http://www.tirerack.com/tires/tirete....jsp?techid=30
Premature dry rot is not normal and can be a warranty claim, mine were. Unfortunately, no amount of scrub will bring the grip back and will noticeably understeer assuming the rears are good. It would also be more prone to failure. If you just use the car for parades, it probably won't matter and you won't notice the grip loss.

No track use just weekend drives with PCA and other car clubs (aggressive but not crazy). Thinking about a few trips in the next few months that would be +/- 2500 miles, so just hoping it's somewhat normal since I have so much tread left.
Another Austinite here... similar car in similar conditions so I thought it would be interesting to compare.
Although my P-Zeros are only a year old, I thought I'd look to see if there was any hint of similar cracking. I see zero cracking, but admittedly I may have had some spirited driving and autocross that chewed on the edges a little bit. The P-Zero is shown in the first photo.
Even the Michelins on my pickup truck, which are within a few weeks of the age of your tires, show no such cracking. That is shown in the second photo.
The last time I saw tires with cracks like the ones you show, the tires were more than 6 years old.
My thought is it wouldn't hurt to check with where you bought the tires and see if that would be covered under warranty. It wouldn't cost them anything since they would be reimbursed by the manufacturer for any replacement work, so I imagine they'll be honest with you.
