Brake discs Bosch or R1 Concepts

I went with R1 concepts. Really good brake rotors and brake pads so far. I’ve had their regular ones and just switched to drilled and slotted. I’ve noticed an improvement in braking after driving for a while as the brakes don’t heat up as much. But it depends on your driving style. R1 concepts kits also come with hardware if you select it which would help because the oem hardware get warn out after a while.

I have used R1 concepts geomet drilled/slotted rotors twice. The pads were pretty dusty but worked well.

Wagner Pads, Bosch QC Rotors. Duralast pads are made by Durago, available on RockAuto. They’re nothing special but they work fine. I like Wagner brakes, other good options include Bosch, Centric and Reybestos. For materials; Ceramic will be quieter and less dusty. Semi-metallic usually have higher fade point but are noisier and let off a fair it more dust which coats your wheels. I’ve been having good luck with the Bosch Quietcast rotors. Advice High Carbon are probably actually be the best option but are one of the more expensive options. Raybestos coated also seem to hold up decently and are a little cheaper. Just avoid anything drilled or slotted it just acts as a cheese grater and acts as less surface area for the pads to grab.

I just did mine brakes & rotors on my 2019 1.5 and all parts from R1 Concepts, drilled & slotted. Feel so smooth!

I’ve used R1 rotors for over 15 years on everything from a Dodge minivan to all three of my BMW’s. I have not ever had one issue and will continue to buy them for years to come.

When it comes to rotors and pads, Bosch Quiet Cast are much better than anything else I've tried in 25 years of XJ ownership.

I think it comes down to the composition of rotor itself, the resilience of the coating and probably manufacturing process, they seem to last and perform a lot better than even the other premium coated rotors I've tried over the years. Similar to OEM German car rotors, they still look like new even after multiple Canadian winters.

I think I did some deep dive research and settled on Bosch quiet cast with Akebono pads. I think I’ve also used eccentric in the past. No complaints with any of the above.

Got Bosch for my brakes and rotors. Just make sure you know which rear rotors you have. First time I accidentally ordered the 316mm from Rock Auto and they were slightly too big.

I have seen the Blaster coils burn Bosch rotors down to a stump. I don't know if something might have been wrong with the system--timing, wrong plug, etc. But it happened.
