The F430 probably only makes 400 at the wheels however has traction control and paddle shifting. I am sure your car is making over 450 at the wheels because mine does and its a tweaked 427srtw. Superperformance 427IR= awesome ride brother!!!!

The F430s are about 430 corrected wheel HP and run about low 12s around 118 mph on a good day with a 1.8 or 1.9 60ft around here. |
