Hello everyone, I want to upgrade my front brakes on my 2012 SRT8 from the factory Brembo 4 pistons to the Brembo Grand Turismo 6 pistons. I have the factory 20x 9 -5 x 4.5 offset black pocket wheel. The system obviously fits the 08 and up Challenger SRT8 vehicles, but will it clear the factory SRT8 wheel. Possibly have to get a wheel spacer in 3mm or 6mm? Thanks.
