Slotted rotors for the M1.

Installation was a little long because I'm a slow worker:). I have Axxis Ultimate Pads with them. Once installed they look great with the black painted calipers! Had every thing all good and checked before bedding in time. Bedding in is VERY important! I had a procedure like so: 1 trial: 50mph to 10mph stops. Do it 6 to 8 times trying to contain speed and not having to come to a complete stop. Once done this is the 1 trial. Have a 10 to 15 min. breaking period for them to cool down. It will smell and might even be smokey, but don't worry it's normal. Redo the same procedure to complete a second trial. Park it at home and leave the E-brake off and have it on blocks. Should be good to go for normal driving the next morning.

After bedding them in they are terrific! It now feels safe to drive since I had some warped to the warpest rotors before the install. Looks are awesome behind the OEM wheels, but will REALLY compliment some large spoke wheels. I would do it again in a heart beat! Except if you have more money than $400 go for the 1.8L brake upgrades w/ powerslots. But for daily driving it's perfect.

Power Slot Brake Rotors

I've had these rotors installed at all four corners for close to a year now. They've been good in all respects. The rotors are of a very high quality. They are zinc plated and I believe the plating is good, because they look as great now as the day I put them in. Peformance has been good. I know they haven't contributed significantly to any dusting, because I don't have a dusting problem (I use CarboTech Super Street F pads with them). I understand the rotors are made by Brembo, which has an outstanding name in brake systems, and are then slotted and plated by other firm(s). I originally was thinking about cross drilled rotors as an alternative. It's a complicated topic concerning which is better, but I'm glad I went with the slotted version. If cross dilled rotors are done well, you can end up with great results, but the high stress concentrations at the hole/rotor surface transition is what concerned me. These rotors came from RSpeed.

I'd buy again because of the quality and looks. I'm not totally sure of their contribution in relation to the pads and SS brake lines I put in at the same time.

Slotted front rotors designed to increase braking.

Installing the rotors was very easy and took less than an hour. I'm not real sure if there is an improvement in braking. I know that there is a lot more brake dust on my rims, so the slots must be doing the job. Visually the rotors are great. Brake dust does collect in the circular groves of the rotors.

I am using the stock brake pads because my Miata only has 5000 easy miles. I ordered a set of EBC Greenstuff brake pads. This should cut-down on the brake dust. I'll let you know in my next review.
