High Carbon Iron Meets Cryogenic Treatment

This front rotor combines two separate durability advantages: a high-carbon iron casting for better inherent heat handling, and StopTech’s CRYO-STOP cryogenic treatment on top of that for further grain refinement a genuinely premium rotor construction for the 2005-2007 WRX and STI.

Two Upgrades, One Rotor

Rather than choosing between a high-carbon casting or a cryogenic treatment, this rotor combines both approaches, giving owners of these now-aging chassis a rotor that’s built to outlast a standard replacement significantly.

• Front rotor for the 2005-2007 WRX and STI
• High-carbon iron casting for improved heat handling
• CRYO-STOP cryogenic treatment for refined grain structure
• Better resistance to heat-related warping and cracking
• Direct bolt-on replacement

The RallySport Take

If your 2005-2007 WRX or STI is due for front rotors, this combination of high-carbon iron and cryogenic treatment is about as durable a plain-faced rotor as you’ll find.
