w1000i thank you for your post, and a description of how this works in the Mazda 6.
I ordered on Saturday KSport 330 mm. Unfortunately it is my country dealer CorkSport. The nearest is in Germany. But I waited too long to answer a lot of questions, especially the question of the availability of spare parts, their prices and replacements discs and pads. Dealer Germany did not respond at all, and the US would send me to Germany. You see they do not want to sell unless it .. And I was really determined. But as there is not. Fortunately, there is competition. Distributor Ksport in my country, and at the same time it is going to put in my car. Also full support in the purchase price. And the price is the same as CorkSport, and saving money on installation.
From your description of the problems that you have no problems.
It is quite normal that they are noisy. And most probably more than 100 km / h it is quite significant sound. So it is hard to have the pads and slots ..
Dusting is laying the pad most probably, but also do their slots. I hope durable with harsh use of 20000 km .. That you wish.
For sure you will be satisfied, because the OEM brakes are not brake above 140-150 km / h. Slowing down, nothing more. Also this BBKit will primarily at those speeds above 160 km / h, and in the end you forget that you have brakes. And this is fundamental ailment and stress in this car.
I have spent over 60000 km, hurt 3 sets of discs:
- Mazda (beat at 22000 km)
- Zimmerman (beat the 1000 km - scary shit)
- SP Performance (I ran out of the blocks and it hurt rubbing metal on metal) and the highly recommend although they are very expensive)
I have spent the 6 sets of brake pads:
- Mazda - 17000 km
- Delphi - 9000 km - a unique piece of crap
- Mazda - 11000 km - changed for another because I changed the brake discs
- Textar - 2000 km - hard, flowing, smelly, dusty brake pad
- SP Performance - 22000 km - the best I had in the car
- ECB - at present - a bit smelly and squealed at the beginning for 300 km, but now takes a nice, little is heard friction pad shield.
And that's why your way - that BBKit is actually the only solution to the problem of the brakes in the car. Maybe someone who rides a duly did not even notice, but as I have to ride at higher speeds really feel the lack of inhibition and after some time bent shields.
