With its most recent improvement, you can now increase the power of your CS to 900bhp, with 774lb ft of torque as a bonus.
Oh, my goodness.
Updated turbos, forged engine internals, sports downpipes, and a sinister-sounding DeepTone exhaust system are reportedly included in the GP-900 upgrade.
There's no indication on how the massive power affects the 0-62mph time, but G-Power says you'll only be able to reach a top speed of 207mph.
That's not too shabby.
If you don't need the entire 900bhp, there are also GP-700, GP-740, GP-780, and GP-820 kits available, each with a different metric horsepower output.
G-Power appears to be willing to tone down the gold highlights on your CS if you ask nicely, and we like both of those 21-inch wheel sets.
What are your thoughts, Internet?
