Honestly I have used these rotors on my car they work perfectly fine they also come with 10 year limited wararnty. These rotors are not any worse than the expensive brands the only difference is the price. If you don't feel comfortable using these that's totally up to the individual but these have a lot of good reviews and so far I'm impressed with the stopping power these provide. They are drilled though so maybe not as tough as the non drilled ones however the holes do help with stopping I can vouch they stop my car a bit better than the OEM non slotted ones.
Mine have been Detroit Axel. Set of 4 rotors and pads and a can of cleaner for a decent price, shipped quickly to boot. My cars go to/from work and an occasional road trip. I'm not hauling anything heavy, I'm not overtly hard braking, and I'm not racing; just a daily driver.
Great quality at a decent price. I've been using them for almost 15 years on everythinng from a minivan to 2 BMWs.
R1 concepts drilled and slotted. Been running them for about two years and theyre solid.
R1 Concepts are the only brakes I use on my cars. Last far longer then OEM.
Have been putting r1concept rotors on my vehicles for 10 years. Corolla, lexus is 250, ford f150, saab 9-3, volvo xc 90. Have always gotten drilled/slotted braking performance seems to be twice as good. The last few cars I know I got my geomet rotors and ceramic pads. But 8 years ago got rotors on my lexus. Felt great never really had a problem. I was showing off in the back roads of wv, super hill, county roads. Maybe a 20 minute drive and I did have the car filled with people. Hit 95 mph a couple times. Everything was fine got back parked, my back rotors were smoking for atleast 10 minutes very visible. Still never had any issues after that. That is apparently super common. Not cause for too much concern. Never had it with any other vehicle any other time. I speed excisively. Just saying if you intend to use them for a track car I'd wanna be aware of that. Who knows if the geomet rotors would've improved things.
I have a drilled and slotted set with performance pads from R1 Concepts (was going ti replace pads but 1 rotor was bad). I have had them for about 4 months now and only complaint us the squeeky pads. I have a larger vehicle (Forester) so i feel the fade a bit sooner than most, but i feel these rotors do a good job of preventing that. I dont ride the brakea that hard but its still noticable.
I have been using r1concepts brakes since my first car over a decade ago. There brakes can be found at jegs, amazon and rock auto. Compared a 2021 receipt to current. I don't have any experience with powerstop. But r1 concepts brakes are way better then factory I've gotten metallic and ceramic pads the eline and geo line of rotors. Geo was so good. Typical rotors in the winter when you park in the garage and the next day the first brake has that squeal where your breaking the rust off of the rotor the geos never had that problem. I always got drilled and slotted and it definitely significantly improved breaking and I never had an R1concept rotor fail.
I have also tested out detroit axles drill and slotted rotors. they are absolutely way thinner than I expected but still get the job done. I test them on daily driving and they hold up great in my experience. 4 months and going.
I bought mine from Amazon. They are Detroit Axle or something like that. They had decent reviews.
