I know the 1521 is almost NO dust and stops pretty well.

(My 2015 WRX w/ AP brakes/2 pot rears) Those brakes were GREAT.

Porterfields secret sauce is a secret. But I assume it's a decent semi-metallic street pad.
For some reason the Elise guys bought lots of them but...they are Elise guys

thanks, i'll try the ct's, putting in an order now.

elise guys are always different from the rest. their cars weigh nothing too, so its gotta be different for any repeated use

 

Hi Ken,
Do you have a package similar to the Drilled and Slotted Sport Package (rotors, pads and lines) except with the 1521 pads? Do these pads modulate well?

 

I can make one.

What is your email address and zip code?

 

Carbotech makes a great street pad. Just a bit pricey.

 

After getting the new rotors and the Carbotech pads installed and bedded, I can say this combo is 1000% better than the stock setup. The slots and holes keep the dust buildup from being ground back into the rotor, I haven't had one instance of judder in the 2K miles I've driven with this setup. The brake modulation is fantastic; very linear from initial bite to full stop the pedal pressure required to produce smooth controlled braking is very consistent. I wish I had done this 100K miles ago. Thanks Ken for a very good recommendation.

 

What rotors did you end up with? Nice to hear that they've far exceeded expectations

 

Quick update - I got almost 90,000 miles of mostly highway driving out of the pads but that took one pad down to zero pad material left. Never a problem with stopping power but they did make a lot of dust. Just replaced them with Duralast Gold (ceramic) from Autozone so I will let you know how these perform.

Another thing, the drilled rotors grooved very quickly. Grooves are at all the holes. I emailed Brakeperformance with photos but they just said it's normal. The grooves have not gotten thicker/deeper but they are definitely there. When I look at drilled rotors on other cars (ie: Porsche, BMW) the rotors are smooth, no grooves.

 

are these BreakPerformance.com rotors.?
