Summary:
I purchase these from a local performance store. I had wanted to try some sloted and cross drilled rotors to increase the stock performance. He told me that powerslot would be a good product would go with, because they will last a long time and they will not warp like the OEM. so I did some research and went with the powerslots.

had the fronts installed with green EBC brakes and in less than a year 16000km they are warped!!! the stock brakes and rotors lasted 30000km's we do 60% city driving with my wife doing a lot of the km's and we are not hard on the brakes. I am shocked!!!

I didn't notice any real difference in the braking with low speeds but I did at high speeds vs the stock set-up.

well needless to say I WON"T be going with prouduct ever again....

Strengths:
looks

Weaknesses:
brake fade with minimal repetition and they warped in 16000km's!!!!

Summary:
For all those people that bash on this product, some just dont know everything that might take into account. I have personally used this product for over 3 years, many canyon runs, heavy traffic braking, many trips down mountains from snowboarding trips. I have always had the power slot rotors in the front with stock rotors in the rear. Pad used were Duralast brand from autozone. The only issue i had with these brakes were a bit of fade during some pretty harsh canyon runs. Im talking about full on 100mph on straights to braking down to 30mph within a few feet. After about 30mins of heavy braking, I do get some over heated brakes and some pretty scary fades. But of course my pads are cheap! But it still does the job after i calm down a bit for only about 2 or 3 turns, then the brakes are up to par. But yeah, only minor fade during some pretty long runs in the canyon. Other then that, everything else seems to brake hard and stop on a dime. Never had them warp. Some people say it might be a defected product, maybe, but you ever thought, when ever you slam you brakes, when they are hot, and you sit at an inersection, holding the pads down on a hot rotor will warp any rotor! Or if you like to drive in traffic and stop your brakes for no reason all the time, this will also warp them. I think its great, of course, you get what you pay for, and this product is what i knew i was gonna get, was all that i needed.

Strengths:
Better looking then blank rotor (my opinion) Long lasting

Weaknesses:
does get hot enough to fade out after some pretty heavy use! and i mean very heavy breaking but for a daily driver with no racing, work just fine

2004 Nissan Murano

Summary:
I was in desparate need to replace the rotors and pads on my Murano and was looking for something better than the stock rotors. PowerSlot had just come out with the slotted rotors. Had a specialty shop (high performance/racing shop) install the rotors and Hawk ceramic pads, broke the brakes in according to PowerSlot recommendations, and have had nothing but vibration and pulsation since. Went back to the garage, the checked everything out, and said they couldn't find anything wrong but that there could be a rotor or two that were off balance (not warped). Got in touch with PowerSlot technical help and they told me the only way they would honor replacing the rotors would be if I took the rotors off, shipped them back and they found something wrong with them, total time frame 3-4 weeks. However, if I put my old rotors back on, they told me I would have to replace the pads when they shipped rotors back out to me. Had the Nissan dealer go through the suspension, steering, and alignment, and no problems found, but they would not touch the brakes given the situation. Just an overall horrible experience with PowerSlot and the product is still giving me vibrations and pulsations. Looking to get different rotors in the next few months and would not recommend these to anyone driving a Murano.

Strengths:
Look better than stock rotors

Weaknesses:
vibrations, pulsations, PowerSlot customer service, failure to stand behind their products

2003 Power Slot Rotors

Summary:
Bought the Power Slot Rotors for my wife's 2003 Neon SXT. She did a lot of highway driving in the hills in the Oakland, Calif area.

The factory rotors would throb, fade, and rumble under down hill highspeed off ramp braking. She also had to deal with down hill redlight stops.

At 42322 miles her factory rotors showed hot spots and had tiny cracks. So I ordered the Power Slot Rotors and Hawk HPS pads. The Hawk Pads cost 61.87$ I use Hawk Pads on my race car a Mazda Miata in SCCA SSB class. The difference was noticed by my wife and my self, far less effort was needed on high speed down hill braking with 3 passengers and a full tank of fuel.

Even after braking hard for 3 or 4 seconds the brakes still had a huge amount of braking force left!

A few months ago we were traveling at 80 mph approaching a split on a highway. At the gore point there were a bunch of yellow barrels. From behind the barrels some idiot back into our path and we had K wall on our driver side and the gore point coming up on our passengerside. The brakes brought us down from 80 mph with ABS activated all the way down to 0 mph.

There was no one behind us thank God. There is no way the factory rotors and pads could have done this. They would have just faded away to the point of the ABS not even activating as they had done before.

Power Slot recommends getting Hawk pads along with their rotors and I agree.

I have since recommened this same set up to a friend how owns a Chevy Trail Blazer. His complaint was lack of braking force and noise. He felt it was taking longer than he thought comfortable to get the vehicle slowed or stopped. He also felt that the pedal effort was too high to slow it down. There was a noise, a "grinding groan".
This was not made by worn away pads but the factory pad and rotor combination. He complained to the dealer and they replaced his rotors and pads and the problems did not change.

He got the Power Slot Rotors and Hawk Pads. He and his wife feel safer now and noticed easier braking and the noise that bug them for so long is gone.

His exact words were "Boy those things really stop"

Strengths:
Great braking force. Have not experienced fading. Have not rusted yet!

These Rotors and Hawk pads are the way to go.

Weaknesses:
None

1995 Ford Taurus SHO

Summary:
Basically, it is a good quality cast rotor that has slots machined in. Nothing more, nothing less. The rotors are not going to give your stock brakes a night/day difference if you have not upgraded pads, cooling, rotor size, or break/season/bed them in properly. I first used these on my '95 SHO with Organic pads. That setup was strictly PAD limited. I used them this way for almost 20k miles. I later moved the rotors on to my '92 SHO when I upgraded to 13" brakes on the '95. When I swapped them over, I also added Wilwood 4-piston calipers with 'PolyMatrix D' compound pads. Since the rotors were properly seasoned with 'soft' pad, they were excellent candidates for some 'cold' track pads and some heavy use. With the Wilwood calipers and 'D' pads, I would find myself slamming on the brakes to feel them work. I would take VERY aggressive canyon drives and track sessions and have the confidence that the car was going to stop. This is all on a 3,300lbs car, 11.6" rotors, and I still retain the dust shields (which hold in heat). I wore through the Wilwood pads in about 4 months and the rotors have NO appreciable wear. Absolutely NO LIP from wear. Yes, my brakes made noise, but that was also due to the pad. The Wilwood pads made the car sound like a UPS truck coming to a stop when the brakes were warm and I was under light braking. The organic pads just had a light squeak when warm. The organics were noisy all the time, but the Wilwood pads only made noise after hard use and some serious bedding under extreme heat. For the people that say they are not better than stock OEM… For the most part, you are correct. As long as OEM is using a quality cast rotor, you most likely will not see any performance increase. Slots aid in clearing the pad and minimal cooling due to slightly more surface area. Because I’ve used cheap rotors that cracked, faded, and warped, I may consider more Power Slots. I was surprised my previous rotors were fading as bad as they were. This is with a 13x1” rotor, directional vanes, Hawk HP-Plus pads, and cooling ducts. Since then, I found a quality ‘blank’ and I have had no such problems. If I have any more problems with rotors, I just may look at another set of Power Slot rotors, possibly cryo’ed too. To sum it up, for those looking for a slotted rotor to give you a real performance upgrade... It is simply not happening. However, when looking for good braking, DO NOT cheap out on the rotor. The Power Slots are just a good quality cast rotor. When SEASONED AND BEDDED properly, they last and stand up to hard use with good pads. If your expecting race car brakes and still retain a tiny stock rotor, near-stock pad, and a cast-iron floating caliper, you won't be much better than stock (tires make a difference too).

Strengths:
Good quality cast (yes, it matters).

Weaknesses:
They are priced a bit high, but I've had bad rotors before and I almost paid by putting a 460hp Taurus SHO in a wall. Slots aren't a bad idea, but I'm partial to a blank cast and a good pad with cooling.
