I'm wondering what u guys think are better brake rotors, Cross drilled, or slotted?

How about both? Roddimus Prime has a group buy in the vendor's section for Brembo slotted and cross drilled rotors. Check it out. It's a damn good deal

slotted are better cross drilled look cooler....

slotted=performance
cross drilled = looks and weight savings (slight)

I'm getting both done on my rotors. I know I'd eventually want both so I'm going to get them done at the same time since it's the same price.

after seeing and cracking so many crossdrilled, I wont use them anymore, only run slotteds

Roddimus Prime

huh, I've never seen that happen on anything short of "race" vehicles. Everyone I know of that has them likes them. Oh well, RB is a racing geek!

damn the school zone full speed ahead..yarrrr

Dont slotted rotors make your brake pad life lesser?

Roddimus Prime

the ones I'm selling are chamfered so while they do cause pad life to be SOMEWHAT decreased it's not a drastic or noticeable impairment to pad life.

Racing Beat

anything but a stock rotor will reduce your pad life, those little holes eat pads JUST as fast as the slots do...

Thanx guys

I've seen it happen on a street car. They look cool, so I took my chances.

If the holes are part of the forging process, this becomes less of a problem. That how the dimples on the Porsche rotors are made.

Neither one is a significant "performance" increase. Otherwise, you'd see them on more race cars. Don't use Porsche rotors as an example...they're not used on most of Porsches models.

I'll shut my mouth when someone can provide an unbiased comparison of stock vs slotted or crossdrilled rotors, all other things being equal. I've seen such a test performed on a Civic and I wasn't impressed. From 70-0 several times, it made little-to-no difference.
And before anybody gets their feathers in a ruffle because their Cdrilled/slotted rotors work so much better, consider this...people typically do them as the stock setup is wearing out. Then with their new rotors, they do new high performance pads, stainless braided lines, better quality fluid and then attribute their new found brake performance to the rotors...when it's really most of the other stuff that's helping.

It's not a Protege. but I've had my CRX for nearly 10 years...I've gone through several brake configurations and can tell you no rotor has made as much difference as the best pad choice, good ss lines and high quality fluid. In fact, I run oem replacement Brembos that work just as well as the high quality/high dollar crossdrilled and then middle of the road slotted rotors I tried before. And the oems are a hell of a lot cheaper to replace. Try getting a crossdrilled rotor turned when they warp. And then warp again.
Cdrilled and slotted look cool and a lot of us can't resist the urge to mod our cars but based on my personal experience, it's a waste if performance is your goal. Spend the extra cash on the best possible brake pads.
