Power Slot Rotors

Power Slot rotors are 1-piece, slotted, direct replacement discs for your factory brake system and stock calipers. They offer improved cooling as well as other advantages the competition doesn't offer. Launched in 1998, Power Slot was the first premium slotted replacement rotor program in North America. Innovations include e-coating, double-disc grinding, full machining, mill balancing and center-split castings, as well as the availability of directional vanes, cryogenic treatment and the use of Power Alloy. Today, Power Slot covers more than 2500 applications, all machined in Power Slot's California manufacturing center. Every Power Slot rotor is a direct replacement for a factory brake rotor, allowing the retention of factory calipers in the system.

Most Power Slot rotors match the original factory cooling vane design. In the most popular sports car and light truck applications, Power Slot has improved the design by using directional (left- and right-handed) vanes to improve cooling. This represents a distinct upgrade from the original equipment rotors, which usually feature a straight vane or pillar vane design. The directional vane is a more efficient air pump. The resulting increase in airflow translates into greater resistance to brake fade and faster recovery from temperature spikes generated by aggressive braking maneuvers.

Power Slot rotors feature a signature "short slot" design. The slot improves brake system performance by wiping away the debris of used friction material that otherwise accumulates between the rotor and pad. This keeps fresh pad material exposed to the rotor surface and helps prevent pad glazing. The edges sweeping the pad slightly increase the effective coefficient of friction, or "bite", amplifying brake system response to pedal input. By providing an escape path for water, slotted rotors can also improve initial brake response under wet conditions.

Every Power Slot rotor is finished with a black e-coating on both sides of the hat, inside the cooling vanes and on the outside edge. E-coating is a superior electro-statically applied finish designed to withstand 400 hours of salt water exposure without rusting. This is especially important on both mounting faces of the hat where it touches the hub flange and back face of the wheel. Any accumulation of rust in these areas can lead to installed lateral runout issues.

Power Slot rotors feature a double disc ground, taper free finish. Double disc grinding ensures parallelism, eliminates run out and provides near perfect disc thickness variation (DTV). Double disc grinding leaves a non-directional finish on the friction surface area for more effective pad and rotor break-in. This special finish also provides quieter and smoother stops.

Power Slot rotors feature 100 percent fully machined finishes including rotor hats. This extra process provides better rotor balance and creates a cleaner, more finished looking component.

Power Slot brake rotors are mill balanced to a tolerance of less than 2 oz-inch. This additional machining operation reduces feedback associated with rotor vibration and provides a smooth, confident application of braking force.

Center-split core castings provide proper heat transfer and thermal efficiency, resulting in superior braking power and safety.

Power Alloy metallurgy is another unique feature in many of Power Slot's rotors. Quality and performance live inside the rotor too. Choosing the correct foundry partner and working to improve the metallurgy are all part of Power Slot's continuous improvement process that helps to reach established targets for hardness and tensile strength. Many of Power Slot's top-selling part numbers are cast using this Power Alloy iron specification, an enhancement in the carbon and molybdenum content of the iron. Carbon and molybdenum promote crack resistance and improve noise, vibration and harshness (NVH).

Lightweight, clean, and effective — worth the repurchase
Scent: White Tea, Size: 1.7 Fl Oz (Pack of 1)
This is my go-to daily sunscreen. It’s lightweight, non-greasy, and absorbs quickly without leaving a white cast. I love that it’s made with clean ingredients and doesn’t irritate my sensitive skin. The white tea scent is subtle and fresh. I’ve repurchased this several times now — it’s one of the few sunscreens I actually enjoy using.

Great replacement for my discontinued Epionce sunblock
Scent: White Tea, Size: 1.7 Fl Oz (Pack of 1)
I really hate it when companies discontinue great products, and even though it cost a fortune, I loved the Epionce mineral sun block for faces. When I realized it was gone, I looked at the Coola line because I like their other products. Found this face sunblock for $32 (this could be 1/3 of the Epionce, certainly 1/2) and have used it for the past few weeks playing golf. So far, so good! I'm not noticing any color, certainly no burn. No irritation, and the scent is quite mild, only noticeable when it's first applied (IMO, and I'm pretty sensitive to scents). I really like that Coola has the Hawaii reef-safe designation, which I think is very important for all sunscreens, even when we're not going swimming in the ocean. As a friend pointed out to me once, even if you don't swim in the ocean, you go home and take a shower and all those chemicals wash down the drain and make their way eventually through the system, so might as well just not use them in the first place! Yes, it's more expensive using products like this, but IMO it's worth it. I also wear sun sleeves these days so I don't have to use as much sunscreen when I'm out on the golf course. Editing this to say that this product has avobenzone, which is actually not so great and may be banned in Hawaii by next year. Hmm. Guess I'll keep searching!

It works
Size: 1.7 Fl Oz (Pack of 1)
I invested in this for its travel size and my needs for a product that would protect my skin and not make it feel super oily. This delivers!!! I used it for a week in Florida with UV up to 11 on some days and didn't face a single issue, even after a Disney day. I was almost in disbelief at how lightweight this product is for it to work properly, but the protection strength is fabulous. I don't burn in the sun, but if I do, its typically along my face where the bridge of my nose is or my upper cheeks. This product basically said, "not today, sun." Bonus, it didnt burn or sting my eyes all day in Disney parks heat, and I didn't need to reapply even though I brought it just in case. Maybe it was the product or the Disney magic, but my skin also didn't look oily or shiny at all in my pictures with the product offering a nice matte finish.

seriously matte-ifying
Size: 1.7 Fl Oz (Pack of 1)
Don’t judge but back in the day I used to use Avon’s “face perfector” because it REALLY cut down on the shininess of face oil and it also had SPF. It made your face look matte without any other makeup. And I am pleased that this gel is similar. No face grease. It’s not even really a gel—if instantly feels powdery (somehow?) in your hand, thus it’s nongreasy. It leaves your face shine free and protected.
