Pics of FCS with Cross Drilled Rotors
 

Thinking of changing my rotors to this.

Why Do you experience fade? You race a lot? Drilled or slotted rotors tend not to last as long because they develope cracks in the drilled or slotted areas.

And even more of a question...why would a picture of them help in your decision? :p: I have slotted only rotors on my Turbo FC. Ive never experienced it myself, but I have known people who have had drilled rotors crack around the holes. There is a huge write-up in the suspension forum about drilled/slotted rotors, and the pros and cons. I suggest you go read it. A rotor is used to absorb energy from the brake pad. Cross drilling/slotting just removes more material that could be used to absorb that heat. But to keep this thread on track.. here is a pic of mine :

my rims are not solid, and you can see the rotor, for appearance purposes i was thinking of putting cross drilled rotors, but if they do crack, no sense of the rotors then

who makes a good slotted rotor (lower price) anyhow?

lol. you guys on this forum are hilarious.

but yeah, drilled/slotted rotors are not the best for a street car.

heres mine..... they are Irotors cross-drilled and slotted rotors....... ive had them for almost 2 years without problems.... and i drive the hell out of my car :bigthumb:

they cost me around $300 shipped for front and rear off of ebay

if lemans cars dont have cross drilled rotors then why would you?

hey vipers, i like your calipers, are they stock or aftermarket?

Higher end vehicles have cross drilled rotors.

:werd:

Do you brake like a mofo? Driving is not what affects the brakes, its stopping that heats them up.

and braking is probably the hardest part of good driving.

i do ALOT of canyon runs!!!!! and before i put the rotors on, my brakes got really hot, and after...... well, i havent EVER had to worry about my brakes not working when i need them to!!! so, they worked for me..... they were exactly what i thought they would be!!! i have no complaints :bigthumb:

they are stock calipers...... i used high temp engine paint, and a white paint pen for the "mazda" letters....... been that way for about a year and a 1/2, and still shines bright!! havnt done the rear yet, ill take pics when i do them!!!

The only reason that a cross drilled brake cracks is because the holes are drilled, not part of the casting. Porsches brakes are cross drilled, but they are actually designed as part of the brake from the beggining. They are not drilled in a sense, but are part of the casting.

Stick to quality stuff and you shouldn't have a problem with craking.

And a good lower cost slotted rotor is Rotora. I know plenty people who run them and have no problems.

the holes are supposed to reduce tempeartures but act like razors.

drilled rotors are bad, slotted rotors have a place.

Not exactly. The whole point of the slots and holes was to vent gases created by the brake pad. The the gases would then act as a buffer between the pad and the rotor. Adding slots or holes was intended to let these gases escape. With modern brake pads, these gases do not exist. Look at F1, or any major racing league.. they all use solid rotors.

So are the stock '86+ brake rotors "modern"?

i have slotted and drilled rotors on all 4 corners.......but its only on there cause they were 125 for 4 off ebay......i couldnt find a solid replacement anywhere for that price......

hell......go on the honda forum and ask them how many honda models come with 4 piston calipers.......btw...as far as i know...legend type II and NSX are the only ones

^ hell hondas suck . . they aren't true sports carsin any respect, i guess the NSX is "ok"
