I've been looking at getting a bigger brake kit for my ecoboost and don't want to spend $1300 on one the high end brake packages. I recently saw an article on american muscle saying that the base GT rotors and calipers will fit the base ecoboost. Just wondering if anyone else has looked into this at all or tried it?
I would think that all suspension & braking parts are interchangeable amongst all the same platform specific Mustangs since they are all identical except for their drive-trains.
There are three Mustang brake packages available, depending on model and equipment. The first is for the standard Mustang V-6 and Mustang EcoBoost, and includes 12.6 in rotors front and rear; two-piston, floating calipers in front; and single-piston calipers in the rear. Mustang EcoBoost models with the Performance Pack and standard Mustang GT models are upgraded to four-piston fixed calipers in front; single-piston calipers in the rear; and 13.9 in rotors in front and 13 in rotors in the rear. The Mustang GT with the Performance Pack has six-piston Brembo calipers front; single-piston calipers rear; and 15 in rotors up front and 13 in rotors in the rear.
You should have no problems upgrading your brakes using stock Ford parts sourced directly from the dealer if need be. In fact if I were you I'd call around to the local junkyards and see if anyone has totaled out a new model GT. You might get the brake components for a steal.
