 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).

Cigarette smell; didn't work
Size: 4 Fl Oz (Pack of 1)
It seems authentic (compared to another brand I had bought) however............the smell is not that great. At first it seemed like coffee smell, but after rubbing into scalp it smelled like smoking/burning cigarettes. It's not horrific but the smell is noticeable. I wouldn't go out in public until after it's washed out of your hair. Hoped that it would help with hair growth but it didn't. The oil just made my hair fall out more.

Appearance, texture, and smell pass the test!
Size: 16 Fl Oz (Pack of 1)
I am rating this product on a appearance, texture and smell alone because I have not had time to use it in order to determine it's hair nourishing properties. I have studied a lot about Botana oil because there are so many products out there that have been born out of a few large names putting it out there in the market. It smells exactly like it should which is coffee and a little bit of Ash. I know that sounds strange but it really is not a bad smell. The texture and the color seem to pass the test as well. The color is a yellow brownish color. The texter is more like a butter as opposed to an oil. It puts you in the mind of shea butter. I did take a little bit out of the jar to see how oily it is and of course it's oily but once you melt it in your hands and rub it in it seems to soak in easily. This protect solid while in the jar. 100% Botana oil should never turn liquidy at all unless you have it in a very hot environment of course. I'll come back once I use the product to determine how it nourishes my hair.

Good Product
I love this brand, but haven't been able to find it lately in stores in my area. It's probably the best self tanner I've used overall. Shipping from this seller was pretty quick. Color is believable- even on my pasty pale, next to white skin. If you're like me, you have to be careful of products that turn you orange. With the "dark" shade, you still need more than one application to actually be dark. To me, that's okay because you can control the color. First application gives a nice color, second application gives a deeper tan. However, I may get the ultra dark next time. I love the sprays best because they dry fast, give the best, most even, controllable application and I have better luck with these than lotions. With lotions, you are gooey and sticky and there is more stuff transferring on your clothes. Never wear white anyway when you first apply self-tanner! Best to do it before you go to bed. I really like that it is tinted. Not only do you get an instant, believable color while you wait for the self tanner to do its job, but you can see where it goes so you don't end up with streaks. Because of the tint, place an old towel on the floor as a drop cloth. Wash your hands between applying to body parts to avoid staining your palms. Yeah, the usual Self Tanning 101 stuff. You do end up with a hint of that self-tanner smell and I have used other products that are better as far as this goes, but it's nothing too bad. They all have that smell to some degree or other. Your tan lasts about 4-5 days and is easy to exfoliate off, without flaking off in weird patches. Best of all, this product is cruelty-free and no animal testing!!

A fantastic self tanning product.
I have been using this self tanner for years. So glad Amazon carries it. It's a bit tricky to use and be prepared to use in an area that is protected. Like using a drop cloth and using care with surrounding areas. It also can stain hands and feet so use gloves and cover the bottoms of your feet. The good part after all that is ,a beautiful deep rich tan. I have fooled many using this product. You cannot spray too close or it will run or not go on evenly. It also at times has faulty cans that drip and are messy. Used to that after all this time. The liquid that leaks is green. Now after all that, it does not sound all that appealing but, trying to give some guidance because it is worth the effort. I have heard rumor that it was used on the show Baywatch to give them that true sun kissed bronze look. It literally in one spraying has you tan. You can darken by using every few days. I usually spray it on before bed, let it dry well and wear overnight to let it set up and develop. It has a sort of almond scent so the smell is decent. I will mist my face alone if I just want a bit of color during the colder months before I leave the house . I just mist a bit less and let it dry. Not saying this is the most user friendly product but, will keep working around its faults to keep glowing. Best at home tan as good as a spray tan from a salon.

Beautiful bronze color!
This is a nice spray mist tan that gradually gets deeper in color within a couple hours after application. It did not make me look orange at all rather a great beach bronze color. It’s a bit difficult to spray my legs evenly all around while staying within the range/ distance it recommends in order to avoid lines, drilling and streaks. Next time I’m asking my friend to spray me. The spray mist on skin will stay on for 3 days before it begins to wear offs. I suggest exfoliating in between spray tanning
