There is no getting around it, the OEM brakes on the Fox are pretty horrible. For years the "go to" option was to upgrade to the Cobra brakes which got you a better PBR caliper and larger rotor. At the end of the day, those are still OEM components and have limitations. For a car that only sees street duty they will do the job but if you plan on hitting the track, making a proper upgrade in brakes should be high on your list.
Any big brake kit is going to have a high initial hit to the wallet, but one thing that is never really talked about is "cost per lap". You can continue to put in expensive track pads with OEM rotors but you will wear through both those components faster than you would if you had a motorsports quality caliper and rotor. Better calipers and rotors will preserve the pads longer and wear more consistently, saving you money in the long run all while providing braking performance that you will never get from the OEM units.
