grooved, cross drilled or dimpled thoughts please!?
 

hay guys....input please....
Would u go for grooved, dimpled or cross drilled or a mixture of the above? Personally i like dimpled and grooved..look good and less prone to stress fractures then the cross drilled..(just having probs finding any!!) :cool:

I'd go with OE blanks. WTF is dimpled?
If you are going for looks, drilled as long as you buy a quality brand.

dimpled are exactly wot they say on the tin!! they have the dimples to cool and remove debris but the hole doesnt go all the way through an thus are stronger but with the same benefits...Def dont want oem blanks, i like the look (and performance) of upgraded

Slotting, grooving and dimples just wear the pads down faster. Still with OEM blanks for best results.

I can't figure what dimples would do. Wouldn't they fill up with dust and dirt?

What performance to you get with drilled and/or grooved?
If you like the look, fine. Don't kid yourself regarding performance.
Quality pads and sticky tires will stop you far faster than any kind of rotor.
To me stopping distance = performance.
I have yet to cook my brakes with OE blanks.

Edit: One of the first sites I found 'dimpled rotors'.

Come on. Just read it. The look of cross drilled without cracking problems.
It's a gimmick. Nothing performance about it. Strictly show. But that's what you are looking for, OK. I prefer function over style.

Anything that reduces the surface area that the brake pad has with the rotor is going to negatively affect your braking. Cross drilling, slotting and dimples are take away rotor surface area. It's simple physics.

Just to add my two cents... as ive seen BMW knows how to make their brakes most effective, but their newer cars have drilled brakes. So if they really didn't work then... Why would they have them on the M3 CS, M5, M6, and MZ4 Coupe. I don't know, just putting in my two cents. Moreover I know I had the luck of doing a panic stop from about 90mph. By the time I stopped my front brakes were smoking. My car is a '96 and has the solid front roters, but anyway just figured I would put in my thoughts.

Drilled are mostly for looks. Including Porsche!
A lot of the cheaper drilled rotors are just that, drilled. Not cast.

Your brakes smoking had nothing to do with your rotors.
Most likely it was the gas in the pads and I'm willing to bet must people here haven't changed their brake fluid in years.

I am hard on my brakes doing 115 MPH every lap.
Only time my brakes smoke is when I don't bed them in properly.

dissagree completely...i put dimpled and cross drilled on my '46 and the difference is huge compared to oem brakes..as for them being just for asthetics...ummm nooooo hence ALL high powered vehs use them..for me however yes purely is athestic clearly with a little 1.9!

Then go for it.

The difference you noticed was probably because you went from worn down pads/rotors to new ones, not because of any "performance advantage" of the dimples. If you're going for the look, that's all you, but don't claim any advantage over solid rotors.

Proof? Decide for yourself: The infamous altimas.net thread

nope my pads and discs were brand new (approx 300miles i think) when i replaced em.....

Drilled rotors crack. Dont ever get drilled rotors. Slotted ones are better but the dimpled ones are the best. They offer the same stopping power but dont crack. My coach has dimpled and slotted rotors on his evo and they are amazing. Dimpled and slotted is definitly the way to go.

And probably never bedded in properly.
DIMPLES ARE PURELY TO SIMULATE DRILLED.
THEY SERVE ABSOLUTELY NO PURPOSE OTHER THAN LOOKS.
