With all the cop blitzes in and around Toronto these days, you might want to consider spending your money on other performance related items, no? At 185km/h you are already in deep do-do if you get caught...
That said, I used to have an Si and I used to run into the speed limiter on occasion, and now I have an SiR and the sky is the limit, and I have to admit, it is pretty nice.
But, damn, can you imagine the size of the fine, the points, and the INSURANCE if you get caught at those speeds? I shudder to think about it...
