I heard from some one one that we have in the front rotors that it is from the F250 is this true i need to get new rotors for the fourth time so i am looking for other brands i dont want the rotors of ford as they keep on cracking

99.5 Lightning
Downs intake
Superchip R9
Slotted Rotors Front/Rear
Lo Pro Tonneau
Netro wing
Boost & Oil gauge
and soon 2001 look
the faster the better zoomzoomzoom

 

If the slotting is done CORRECTLY they will not crack any faster than stock and will actually resist cracking.I have run slotted rotors for the past 2 yrs and have just now replaced with the second ones! I think the biggest problem is no one knows how to break the rotor in.You still need to "bed" the rotor just like the pads.All the "slotted" rotors that I have seen use a flat end mill to relieve them the one that I do don't. Stan,and I dought their are to many people as hard on brakes as me.I am actually on my 3rd set of calipers!!!

Can you give me a number where i can call you and do you this rotors and sell it i am interested in buying a set from you so if you can e-mail me where a can call you my e-mail is jrs@info.com.ph

I beg to differ with Spike Engineering. I've run half-hour practice sessions on the Buttonwillow (California) long course (3.1 miles, clockwise) using ALL the throttle and 2nd gear to assist the brakes. Magnificent performance! No fade, no uneven pull, no problems. ABS makes it too easy.

 

Hmmm...

I'll have to try that.

Not sure of the compatabilty with the stock calipers, but you can buy just the rotors and hats from Brembo. More $ than stock, but not at the rate you are going through them.

'Light:

Have you "slotted" all 4 sets that cracked? If so, this is the likely cause of your rotor failures. Those slots (same effect with holes holes) serve as magnificently efficient stress concentrators. Hard to avoid cracking, especially with heavy heat cycles.

I realize that drilled brembos are resistant to cracking, but they are engineered from the ground up for holes. Different than drilling them yourself.

 

Quit "slotting" the stock rotors. That's crazy.

No wonder you keep cracking them. This truck brakes as good as C5's and Porsche's from the factory. No need man.

I started with original rotors twice then i got sloted that have been cry frozen but it also cracked but only in the front now even this is going that is why i am asking if the rotors in the front are from what type of truck

If all you're doing is drag racing, then I'd agree.
