After 7,300 miles, my impressions are similar to what they were when originally installed. Aside from wider temperature range driving, I expect the major differences will be realized from 20k to 30k miles.

Likes:
On-center feel and stability is very good
Do not follow groves in road
Do not transmit minor road expansion joints into cabin
Quieter than Michelin tires so far
Much better traction in wet and dry weather with temps in 30s
New--I prefer the Bridgestone’s sidewall appearance over MPS4S

Dislikes:
Tire reaction to aggressive turn-in is lacking at high speeds when compared to both sets of Michelin summer tires.
Difficult to use on a prepped racing surface (drag strip)
- Spin during launch, but have not tried below 25 psi yet
- Not sure if it's the psi, weight of tire or the tire's harder compound but they seem to cause axel hop (more than other tires) on a prepped drag strip. Axle hop only happens at the drag strip and has not happened on a normal road surface.
