Orange County's Dime Research Development started as an engine specialist, only to expand into motorsport with the know-how gained as tuners. Currently, Dime Racing runs an SLS AMG in the Pirelli World Challenge, but will also sell you a very fast AMG GT for the road, followed by an E63 and a C63 soon enough.
For that, Dime gives you a carbon fiber aero package–including a front splitter, the grille, side skirts, diffuser and a massive wing–as well as upgraded cooling, adjustable suspension, a lightweight exhaust and sticky Pirellis. Oh, and a V8 with better turbos and a new ECU for a total output of 745 horsepower and 731 ft.-lb. of torque. Trust me, it will be loud.
The base price of $150,200 might sound a bit hairy at first, but given that the AMG GT S starts at $130,825, you can have a fair guess how much a 577 horsepower GT R will set you back with, not to mention the even crazier Black Series coming in 2019. 745 horsepower with a warranty is a lot of juice for the money.
