4 drilled and slotted for 199$?

Too good to be true?

Yes. Most rotors like these are cheap castings and the holes are drilled afterwards and that can cause cracking around the holes if you are hard on brakes. The extreme heat generated by hard braking causes the metal to expand and contract and because the hole is right where the rotor get the hottest, the area around the hole will crack in an outwards fashion arond each hole. The slots are machined into the surface of the rotor and will probably have very sharp edges and will cause premature wear on the leading edge of the pad as the slot goes by in rotation. Some pads are chamfered around the edge to help with this. Some drilled rotors may even require a semi-metallic type pad and that usually means much more brake dust.

Expect to pay at least $100 each for quality drilled rotors but they still are really for normal street driving. Extreme braking like that encountered during Driver Education or open track days will kill cast and drilled rotors.

For track and autocross use, I buy the cheap standard rotors and toss them after a few events. Usually pay about $25 per rotor.

c4cruiser,

Very good response!

Now for a question: who makes a reputable drilled/slotted rotor? Are they worth it for a daily driver?

Great reply -

Sounds like the drilled/slotted rotors are really for show and would do fine on a sunday driver or show car. Anything driven daily or with the rare extreme braking needs had better be sporting higher quality(drilled/slotted) or solid rotors.

If you want the look factor, Raybestos makes a decent drilled/slotted rotor as does PowerStop. NAPA has one that is made by Raybestos. EBC also has slotted rotors that should work for heavy brake use. The problem with these is that they say you must a semi-metallic pad with them. More brake dust, but sometimes thats just part of having a high performance car that stops as well as it goes!!

Baer is a very good rotor as is Wildwood and Alcorn. These can get real pricey but if you're a serious track day type, they would be worth it for tracks that are hard on brakes.

Get What You Pay For

Judging from the feedback they have, I wouldn't buy from them even if it was a good product unless I had someone pick them up and they sent them to me

If you want the look, but don't want to deal with cracks, go with some dimpled/slotted rotors.

Don't go with drilled rotors!!! DON'T
