Product Description
StopTech Power Slot 02-10 WRX Front Left or Right Sportstop Slotted Rotor
Venting the gas emitted by hot brake pads improves overall brake performance and helps minimize fade. StopTech Brake Rotors are specifically designed to run cooler. In fact, all applications have superior metallurgy and design specifications, including vane designs (with some applications featuring curved vane designs) to further promote cooler running temperatures. And the StopTech Brake Rotor's slotted design dramatically improves wet and dry brake performance and is a safer alternative to drilling crack prone holes through cast iron rotors.
The slotting process removes far less of the rotor's surface area than conventional cross drilling to help maintain the highest possible co-efficient of friction for the brake pads to work against thus increasing initial "bite." Slotted rotors trade only 3.7% of their surface area to the slots that vent the gasses, while drilled rotors sacrifice up to 7. 75% of their surface area, and rotors that are both drilled and slotted sacrifice up to 9.38% of their surface area. Less surface area means less stopping friction. The rotors are also double disc ground and mill balanced to ensure a consistent friction surface and improved pad bed-in.
The short slot designs of StopTech rotors run perpendicular to the vane to preserve rotor strength and are angled to use the rotors' direction of rotation to enhance performance. This makes them side-specific with left side (driver's) and right side (passenger's) rotors.
StopTech Brake Rotors' black Electrocoating (E-coating) finish, an electrostatically applied finish is designed to withstand 400 hours of saltwater exposure without rusting and provides long lasting corrosion protection in the critical hat and cooling vane areas.
Excessive heat can cause resins in your brake pad to vaporize or "outgas." As the brake pad wears, the used friction material turns into a fine dust. This boundary layer of heat, gas and dust builds up between the pad and rotor surfaces and inhibits performance. Here's where StopTech SportStop slotted brake rotors make a big difference. StopTech SportStop Slotted Brake Rotors are a true performance rotor and feature:
Power Alloy castings (on select applications)
- Engineered Performance Rotor
- Superior resistance to cracking due to thermal stress
- Increased molybdenum (higher carbon)content that extends reliability, service life and helps reduce NVH “noise” issues
- Rotor material is a direct descendant of the patented AeroRotor from StopTech
Introducing directional curve vane design (on select applications)
- Improved vane design or OE equivalent on all rotors
- Center split castings
- New short slot design runs perpendicular to the vane to preserve rotor strength.
- Direct OE Replacement
- Improved wet weather response
- Increased initial “bite”
- Double disc ground for a consistent friction surface and Improved pad bed-in
- Mill balanced
- Black E-Coated non-friction surfaces on “Power Alloy” rotors
- Enhances open wheel appearance
E-Coating Advantages
- Uniform coating thickness over all areas including sharp corners, recesses and areas that would be hard to reach with spray painting
- Paint material is water-based and nontoxic
- Approximately 95% utilization of paint with no overspray, drip or drain losses
- Complete paint coverage — no touchup ever required
Select applications also benefit from StopTech technology that results in a completely engineered performance rotor with superior resistance to cracking due to thermal stress. These specific rotors' increased molybdenum (higher carbon) content further extends reliability, longevity and helps reduce NVH "noise" issues.
Designed to beat the challenges of high performance driving and severe duty brake demands as well as to enhance open wheel designs, all StopTech Brake Rotors represent one of the most cost-efficient performance brake upgrades offered in the market today.
