the only reason i brought up locking up the wheel/activating ABS is because you did in your original post...

The average car on here though is a WRX which is fast and has good handling and aside from the 06/07 has poor brakes and comes from the factory with weak brake pads. The 06/07 has OK brakes but still has weak brake pads. The front rotor is too small.

Subaru agree's - in 2009 they increased the mass of the rotor.

Many owners on here further increase the acceleration and handling of their WRX (ability to alter the velocity vector) yet ignore the one velocity vector that is most likely to injure them.



Ability to lock up the wheel/engage ABS is irrelevant to braking performance.

1 - You cannot steer the vehicle if the wheels are locked
2 - If the wheels are locked than the rotor is not moving in relation to the brake pad. This has no bearing on brake performance as static friction always exceeds dynamic friction.

The brakes at a minimum need to be able to slow the car at the tires limit while allowing the driver to control the vehicle. Never mind performance driving of any kind - Subaru brakes are marginal at best. Mushy compliant pedal, overboosted system, the braeks feel like they coem from a minivan or something.

Drive a Miata w/ Hawk HPS- drive a WRX w/ HPS - I did. Night and day.

Installing performance pads and high temp fluid IS an upgrade btw.

I had a 97 Outback. It's brakes were terrible. It would only lock up the wheel with pretty excessive pedal pressure if at all. Foot to the floor and keep pushing. It had beat AS tires on it. That is no way to control a car and I could not let me wife drive it.

Installed some good friction semi-metallic pads and fluid flushed and it was great. Lasted a good long time as well. It was the PERFECT upgrade for that car.
