Why are we cutting up this Camaro?? We announced our Mopar B-Body full ExtReme IRS chassis, and we followed that up with our Mustang IRS chassis. Does that mean we are bringing our award-winning geometry and components to the F-Body (Camaro and Firebird) platform soon?? 😈 #SpeedtechPerformance #PerformanceDRIVEN #NewProduct #New #Innovation #ProTouring #Chassis #Suspension | Speedtech Performance
