R&T has a nice one page review of the 04. They had a very positive impression. They confirm the more predictable handling due to revisions to the rear suspension. The also indicate that turn in isn't quite as crisp as the earlier cars. They had the best description of the added power yet. They did some rolling acceleration tests and found the car accelerated from 35 to 70 (I think) about 1.2 seconds faster. While max torque increases only 5%, torque at lower RPMs is up a full 10%.
