Our performance packages make it easy to assemble the best possible combination of mods and tuning for your car. These have been extremely popular for ATS-Vs and CT4-V Blackwings, and now we have similar White and Blue Belt Performance Packages available for the CT5/CT5-V cars with 3.0 liter LGY twin turbocharged engine. Blue Belt includes performance air filters, intercooler fill/bleed kit, colder spark plugs, EPA catted downpipes and tuning. You’ll have a new powerband that’s 10 to 50 whp stronger everywhere, and extends an additional 500 rpm. We busted out a 3.9 second 0 to 60 mph time on our first try! Plus the exhaust and turbos sound so much better with the downpipes.
