Kits include 2-piece directional floating rotors with directional billet aluminum mounting bells. (pre-assembled) 2-piece rotors allow expansion without coning. The parts are up to 8 pounds lighter than stock rotors and push up to 61% more air for better cooling and reduced fade on the track.

This specific kit will fit the 2004 STI, 2005-2007 STI, and 2008 STi. Hats are drilled for 5x100 and 5x114.3 Bolt Pattern
