Very nice car and you did a great job, but something I can't understand is why people like you get 650i and spend 20-30k easily to make their car looks and performs like M6 while it's not an M6 yet? I mean for sure you have spent 20-30k for exhaust, wheels, brakes, suspension, Dinan,... and still you don't have enough performance to compete with M6... with Dinan stage 3 still you have 100HP less than actual power of M6...isn't the different between the price point of M6 Convertible and 650i Convertible 25k? not to mention that M6 has all factory installed kit...
