Had mine to 130mph. I have mods and a tune. The limiter is disabled. It prob due 140mph but as mentioned in this thread, you must have speed rated tires. I have z rated 225/50r17. And yes, thats prob the fastest I would go. The C suspension and single piston calipers are not up to the task even w the minor brake upgrades i did. Have fun but be smart about it.
