So I installed a Wilwood kit meant for a ~2008 vintage WRX on my 2010 Legacy GT. I bled all the things, and went for a drive. I can pump the brakes to get pressure, but on driving and attempting to stop, the pedal goes quickly to the floor (feels like it gets resistance, then fades, then resistance comes back close to the floor) and the car does stop, but not well enough to drive. I can not lock up the wheels. The kit is meant to be used with the stock master of a WRX. Is this unit much larger than the LGT Master? Is this a brake proportioning issue? Does anyone have any experience or thoughts on this? Maybe the kit is just too far mismatched with my car.

I appreciate any help, Opponauts!
