<-----Brake Upgrade Scion xB 08+----->
Stoptech Rotors with protective e-coated hubs are now in stock! These rotors are for the 2008+ Scion xB. We have 2 versions of the rotor both being 1 piece direct stock replacement. The first is a slotted rotor.
Slotted Rotors: Refers to a rotor face that has been machined with a hand full of shallow grooves. They come in all shapes, sizes, and patterns. Even though pad technology has surpassed the first generation there is still evidence of gassing out and brake pad dust lubrication. These slots give the gasses and brake dust particles a place to go. The last place that you want to see gas and dust is in between your pad and rotor friction surface. They will essentially lubricate the surface and hinder your cars braking performance.
Another benefit to the slotted rotor is that it can help prevent glazing. Glazing refers to the brake pad getting so hot that its chemical composition changes. Machined slots help remedy this by shaving a thin layer off the pad giving you a fresh surface to surface contact between the friction disc and pad.
Cross-Drilled Rotors: These are simply a blank rotor with small holes either drilled or cast along the rotor face. There has been great debates on the structural strength of a cross drilled rotor that has been cast with the holes and with the holes drilled in a second process. Initially these were developed to help vent the gas build up of ancient (1950’s) brake pad technology. While these holes look flashy and catch attention they do not provide a performance gain that justifies the material loss. The holes can bring more cool air into the rotor veins, but I do not see this benefiting your stopping power. I would rather have that mass back in the rotor to help absorb the thermal energy.
Cross drilling can be beneficial if you are looking to scrub every ounce and bit of performance out of your hot rod. Take a looks at street bikes, formula car, or carts. These all use light weight cross drilled rotors. They have less rotating inertia.
The downside to the flashy cross drilled rotors is that these holes will accelerate cracking and rotor fatigue. I have ran cross drilled rotors on my street cars for years with no significant signs of premature cracking. However, on the full fledged race car, these rotors will simply not last as long as a slotted or blank rotor. They will also chew though your pads much faster than a traditional rotor. The choice is up to you.
Posi Quiet brake pads.
The perfect compound for both spirited street driving to the occasional weekend track event.
* Long wearing
* Low brake rotor wear
* Stable friction performance across wide temperature range, particularly higher temperatures
* Excellent for street driving with mild street use.

SL has been off and on for me today so please bear with us. The order has been placed to get these lines in stock, but we will anticipate a 1-2 week time frame to get them in stock. I will make sure to let you guys know when they arrive.
