well, I'm once again thinking about getting an M5, and was wondering how good some of the Dinan mods are. I would probably get their Cam gear and chip, bringing my horsepower and torque near 300. How much faster would these mods make the car from 0-60? Stock, e28 M5's do 0-60 in like 6.3 seconds right? So, I'm guessing that with the Dinan mods it could be more like 5.5-5.8 seconds or so. What do you guys think? Thanks.
