 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).

OBSESSED - My New Go-To SPF ✨
Color: Glow
I don’t say this lightly - I’m OBSESSED. The Colorescience Glow SPF is hands down the best sunscreen I’ve ever used. This formula makes my skin look unreal - plumped, radiant, and healthy from morning to night. It gives that lit-from-within glow without ever looking greasy or heavy. I’m super sensitive to sunscreens (most of them irritate my skin and eyes), but this one is perfection. No reactions, no discomfort- just smooth, glowing skin all day. I also ordered the Flex and can’t wait to try it next. This is officially my forever SPF

Best Sunblock ever!!
Color: Bronze
I kept seeing this all over my social media, so I decided to do some research before purchasing. I was pleased at how high the reviews were. I decided to purchase and I’m totally obsessed! I’ve been using for a few months now and I don’t even wear any foundation anymore. This has literally replaced it. I love how it glides on like butter, and how It’s so smooth and light. I get so many compliments on my face. Best sunblock ever!! I’m forever a customer! Highly recommended!!

Bronze and Matte are brown girl friendly
Color: Bronze, Color: Bronze
TLDR: I got bronze and matte formulas and I have oily skin. I’m very happy with these. Bronze is a perfect match until it oxidizes so I mix it with medium for the perfect shade. Bronze will be flexible across a wide range of skin tones. Matte formula is perfect on its own, more like a satin matte finish. I think matte has less pigment than bronze. Both are easy to apply and reapply, blends nicely, zero white cast- no Casper. What I liked: I really like the finish on these. I have oily skin and these work well for me. They don’t burn my eyes. Bronze gives a little glow while matte tones down the shine but it’s not too matte, more like satin matte. I can wear matte on its own but I have to mix bronze with medium because it oxidizes after a few minutes. These are both great options for daily wear. What could be better: I wouldn’t change anything about the matte formula. But it can get thick after several reapplications. I wish the bronze formula didn’t oxidize. While it doesn’t oxidize every time, you just never know when it will. But mixing it with medium helps to keep it chill. Skin tone: For reference, I usually have to mix shades to get my perfect match. But my skin tone tans very easily and is lighter in winter, darker in summer. So I mix medium with bronze or tan. Some of my foundation colors if it helps you: Armani 7.8, Hourglass 11, EL DW 4N2, MUFE 3N42, NARS Aruba, Dior 4N, Haus Labs 330. Would I recommend: Yes! This is best for brown girls who want a tinted sunscreen without a white cast. And it’s even for lighter people who want to bronze up their skin. About my photos/video: Photos show me wearing each formula as well as swatches. Hope this helps!

I love the GLOW of this product and that you get some SPF protection. I have used it for years and put on with a serum to even it out and a blending sponge. I would definitely recommend and have bought it as a gift for my sisters

Perfection! Not for very pale skin, unless it’s contour..
Color: Bronze, Color: Bronze
I only deducted a star because it was not perfect for “all skin tones”. I am very pale with cool pink undertone. Where it does give me “healthy color” without being orange (after waiting 15-20 minutes for the color to settle.), which is something I have never had before with a bronzer. I’m impressed. But… as you can see I the photo, you can clearly see where the spf ends and my shoulders begin. I prefer something more subtle so if I decide to take change my top or if my strap moves you don’t see the stark alabaster skin line. That said, if I was going to be fastidious about where my close rest on me, this would be wonderful. Ok now the pros: Goes on like a dream. Unscented, but the smell of the ingredients is subtle (maybe some Shea butter scent? It’s so light I can’t place it) and goes away after about 20 minutes. I have very dry, extremely sensitive skin. I mean… VERY sensitive. This feels like a high end thicker moisturizing cream/balm, but had zero stickiness or oily feeling. When I first saw the deep brown bronze color in the drops j put on my fingertips and then the orangy tint as I first put it on I started to panic. Thankfully it blended in quite well. I have NEVER had a bronzer look natural or not orange on me. So the product base is exquisite. I have bought over 27 face sunscreen products this year trying to find anything my skin would play nice with and my skin actually LOVES this. I further I have it on and I hugged my nesting partner who was wearing a light t-shirt and there was no transfer or oily blotches on his shirt as I have had with most others. I used the original version of this that has a neutral beige tint, the formulas feel identical, though I have not checked the ingredients. What is important here is it layers beautifully! I had the bronze on and because 2 hours had gone by I put the original over it and wow, I love the effect! I still can’t feel it on and it hasn’t pilled or left creases of product on my neck (unlike Elta MD Clear’s 2nd and 3rd 2hour reapplication layers.) Here is what I am squealing with excitement about. Not only does my skin adore this product feel and formulation, but it layers! I am going to try to contour myself with the bronze. Use the Original first, and add contours under my jaw, where blush would go and my temples, blending before the product dries. Because of the way the bronze didn’t shift when I applied the original on top, it is likely that when I apply the other layers of just the original every 2 hours, it should still look beautiful. I WILL be experimenting with how this works and how well it holds up to being outside, then update you here. (Currently I am outside less than an hour, but have enough windows o still get sun burned and sun angry red skin within 2 hours inside my home. So I still want to check for outside direct sunlight efficacy too.) (Before this I was using SuperGoop Unseen Sunscreen, but my face still got red/irritated and EltaMD UV Clear, which had less redness/irritation, but was still causing me mild redness. Everything else was either tacky, oily or had an unacceptably white cast. The closest to 3rd runner up was the “No more foundation” it’s cosmetics moisturizing spf cream. It moisturized with zero skin irritation and had fantastic spf, but I did look like I had a plastic mask which is jot my thing. It appears I have the best of what I adored about “No more foundation” and a clear or unnoticeable tinted spf that looks plausibly natural!)
