EBC Ultimax premium front rotors for 2003–2004 Subaru Impreza WRX/STI use progressively angled slots to deliver quieter slotted rotor operation while improving cooling. The slot geometry draws in air for thermal control and clears dust to keep pad bite consistent and extend pad life. These vented front discs are positioned as an OE-style solution that balances reduced noise with improved braking performance for daily driving.
