I've been doing 135+ everytime I bring my XFIREX to work...in my mile and a half long straight autobahn strip! It's very solid and very stable...no shakedown...seemed to float a little bit but that's from the road imperfection. Crossfire owners should try driving their XFIRE's to the max to get the experience of speed...here in Texas we have an every Friday night races at the Motorplex where you can test your skills and pump up your adrenaline..win or loss!

With the mustangs...yeah slap some superchargers on it and their engine won't last long ...probably lesser life than the end of their loan term!
