LMP Cadillac CT5-V Blackwing 15 Inch Conversion Kit (5505-15CV-1) - 2022-2026 Cadillac CT5-V Blackwing
Putting serious horsepower to the pavement in a CT5-V Blackwing requires more than just engine modifications. The LMP Cadillac CT5-V Blackwing 15 Inch Conversion Kit was engineered specifically for racers and high-performance enthusiasts looking to run a true 15 inch rear drag wheel setup while maximizing traction, improving launch consistency, and reducing limitations caused by the factory rear brake configuration.
Designed around the demands of high-horsepower LT4-powered Blackwing applications, the 5505-15CV-1 conversion package combines modified OEM components, upgraded suspension hardware, lightweight TBM brakes, and specialized mounting components to properly support a drag-focused rear wheel setup. Whether your CT5-V Blackwing is a street car chasing better sixty-foot times or a dedicated drag build, this kit is designed to improve tire compatibility and overall launch performance.
Built for High-Power Drag Racing Applications
The factory rear brake and suspension configuration on the CT5-V Blackwing limits the ability to run smaller drag wheel combinations with taller-sidewall tires. The LMP 15 Inch Conversion Kit addresses these limitations by utilizing modified OEM knuckles, custom caliper brackets, rotor hubs, and a lightweight TBM rear brake setup engineered specifically for 15 inch wheel clearance.
This conversion package also incorporates LMP control arms to improve rear suspension stability and support more consistent power transfer during hard launches. Taller-sidewall drag tires help absorb drivetrain shock more effectively while improving traction and launch consistency on high-horsepower applications.

The 15 inch conversion kit requires the use of LMP billet arms. If your vehicle does not already have LMP billet arms installed, they must be purchased separately before installation.
Vehicles equipped with factory carbon ceramic brakes require the purchase of base model electronic parking brake calipers for both sides. Required GM part numbers are:
