There's a reason why these front calipers are factory equipment on the 2006-2007 model year WRX and many European models; They're awesome! These calipers feature a 4-pot (two on each side of the rotor) design for improved clamping force. For you autocross and track drivers, these calipers also have removable pad clips/pins, so you can change pads without taking the caliper off. These will work with stock 02-05 WRX rotors and lines, all you'll need are pads and bigger wheels (minimum 16x7 - stock WRX is 16x6 and these will not fit). These are a great improvement over the stock 02-05 WRX caliper and offer the reliability and fitment of an OEM part. This kit includes both front calipers and all the hardware necessary to retro-fit them onto your 02-05 WRX. Calipers available in red only.
