I got a set of dimpled and slotted rotors with a black corrosion resistant coating from SP Performance. The black does not stay on the face where it meets the brake pads, but does stay on everywhere else. Pretty good in regions like mine where the DOT salts the s**t out of our roads.
Correct. Brake Performance fam. Link to their site is in the video description.
You could have linked it here, but then I guess you wouldn't make that little bit of commission that you would make if someone followed your link on YouTube and purchased.
I've had the Z1 2-piece rotors for about a couple years now. I bought the drilled and slotted option. Great rotors that are spendy, however they can be rebuilt for a lot less money. No rust, which here on the Oregon coast is a problem. These get the Avedis53 Seal of Approval.
The rebuildability (if that’s word) and the average service life of a BBK/2pc rotor is something a lot of people forget or don’t factor into long term ownership cost. Less frequent replacements and being relatively cheap once needing to replace can make the expensive upfront cost worth it and even out over time. Especially if tracking or frequent abuse. Not to mention all the performance benefits on top of it. And Avedis53 seal of approval has got to add like 20pts.
Is that all?
Its a 10pt scale though.
Alright then.
True. performance, looks, weight are primary reasons people buy, but thats partially my point people don’t consider cost isn’t as crazy long term as people may think.
I see. I actually didn't know BBK rotors last longer. Makes sense though.
If you were comparing apples to apples perhaps but the design and build quality of the 2-piece rotors vs. those BPI-brand machined blanks is substantial.
My review: They are good, but not amazing or ground-breaking. Still has the brake fade, if you are really gunning it. I was racing in Mexico with a GTR and we had to stop twice from 140+ to 0 within few minutes and I basically slid through a light which luckily was empty.

Understood. We know the many virtues of the 2-piece rotors. I'm just saying no one buys these to save money on rotor purchases in the long run. I wouldn't know how to calculate the point of return on your investment but I would bet it's beyond the average car ownership period.
I bought them because they look cool...and are lighter weight. If I cared about the money, I wouldn't do any mods on the car.
Not counting more extreme situation primarily tracking, but also spirited driving, canyons, hwy pulls/high speeds stops where heat is a big factor in wear and in favor for the BBK making the BBK last that much longer.
Brake fade is a function of the pad composition, not the rotors. Pads are designed to work up to a certain temperature. Exceed that temperature and the components in the pad melt and lubricate the rotor. Gases can be generated from heating the pad material and that gaseous layer also reduces friction. Cross-drilling and slots help control heat and removal of pad material and gases but won't eliminate fade if you exceed the recommended temperature limit of the pads. Cross-drilled rotors typically aren't recommended for track use because the high heat can cause stress-cracking around the holes. Higher quality cross-drilled rotors are heat-treated and stress relieved as well as chamfering the holes to inhibit stress cracking which Z1 does.
I do not solely blame it on the the rotors, But the rotors warped and had heat markings on it. I cannot seem to find a pad that suits me, having already tried 4 different pads/rotors.
