Also, that car failed to run at a high speed test sponsored by Continental tires, and it appears to have been plagued by various problems since its birth. Not to mention the kit is something like 185,000 euros (including the car). I think this M3 kit has a long way to go if they still haven't perfected the M5 kit they've spent years on.
On a side note, I was just reading last months BMW Car magazine, and the G Power M5 featured has a front BBK but stock rears. How can you cheap out on a showcase car like that?
Well, it doesnít fair well for G-Power to have experienced such troubles. I personally donít know G-Power from any other source but their advertising which appears to be pretty good. However, I do know of a number of reputable tuners that have had issues starting up their carsí when its absolutely critical. Hahaha!! I suppose these things happen. 800hp+ with a SC for the M5 engine most certainly sounds as a stretch to me even when changing all of the internals, for that kind of power you probably need to induce such a huge amount of air that only turbos are capable of.
