I dont know about your suspension but i think u've been watching a bit to much FAST & THE FURIOUS (i maxed out at 170 ) U NEED NOS MAN
Just kidding dude
My 4m, the predecesor to the 7m could do 175kmh when it was stock as a rock, I have since done a LOT of performance wise stuff to it but havent been able to give it a speed test for 2 reasons 1. I've lost my licence for speeding wonder why?
2. I'm still wearing the freshly re - built motor in but i reckon it will do the 200 easy.
