drilled and sloted Options

[Dragondog]

where is a good place i can get drilled and sloted rotors......no i wont do it to standerd disks......i found a place in ca that sells them for 69$ for frt pair what do you think others for 107$ a disk

Sorry if im beating a dead horse , but i am in the market for new front rotors too, so ive to throw in my 2 cents

It seems the big gripe about drilled and slotted rotors is that they decrease the frictional surface area for the pads to make contact with.

Isn’t that the same concept as those four and six puck clutch disks? By limiting the surface area you greatly increase the clamping force at four or six points, while sacrificing lifespan of the friction material and smooth engagement.

So
Drilled and/or Slotted = lots of bite but short lived pads


Also, holes and slots increase surface area of the rotor as a whole, therefore it must cool faster than a standard rotor.

B-R-A-K-E-S are different than clutches. reducing the surface area of the disk is not going to give you more bite at fewer places. it gives you less braking power in less places.
That and I'm really going to assume you don't know clutch theory and it doesn't apply to braking.

colder rotors = bad. BRAKING power works off of heat + friction. Drilling is PURELY ASCETIC there is no functional benefit from them, Porsche and Benz already said they do it for "style".

as well as where you live has ZERO to do with the type of BRAKE pads you need. CITY driving has to deal with INITIAL BITE of your brake pad. This is an issue that comes down to COMPOUND construction. You don't need "performance" BRAKEs to drive there, you need to not follow so close to people/drive slower in traffic.

but this is now a dead horse. Do your research on B-R-A-K-E-S and you will learn about how they work and what is effective. (Thus I mean research from scholarly documentation, not ricerRus.com )

look closely, solid rotors much faster than any swap here and endures much more braking demands.

Mine too? I still think my points are valid [and if you look I pretty much agree with you]
