In other IS-F modification news, Japanese performance company HKS has released a speed delimiter that allows the IS-F to pass its computer imposed speed limit of 170mph (273km/h).
Dubbed the Velocity Advanced Computer, or the VAC, this tiny black box is wired into the IS-F's ECU and will let speed-crazy drivers test the upper limits of the 5.0L 416HP V8. So far, it's unclear just how much top speed the limiter is suppressing, but I'm sure we'll see some insane speedometer videos on Youtube any time now that will answer that very question.
The HKS speed delimiter is available in Japan for ¥157,500 ($1,550USD). Again, no word on North American release.
