Unless you are in germany (autobahn) or track the vehicle once per week, The dinan stage 4 550 is a pretty impressive substitute for $ 20,000 to $ 25,000.00 less. Dinan stage 4 550 0-60 in 4.3 seconds and the 1/4 mile in 12.3. Not bad for a poor mans M5.
A brand new 550 is about 70k+ 25k for the dinan upgrades= I should have just bought an M5 at 95k
Where is the logic? And you get alot more perfomance upgrades such as wheels, suspension, brakes, etc............
