please help me to figure out which is better hawks slotted or cross drilled and..

[bluecmaro96]

Are hawks racing slotted rotors better than cross drilled and slotted rotors? I just want to know if the cross drilled and slotted ones are betterthan just the slotted ones? thanks

Unless you are running a race car, Cross-drilling, slotting, both, acid treatments and the like are all cosmetic..

The real braking power on rotor upgrades comes from a larger rotor (more surface area and larger time between the same point on the rotor hitting the brake pad again, so it has more time to cool off) and/or adding brake calipers with more pistons (again, more surface area). I don't know of any 6 piston kits right off for F-bodies, but I know they make them for Rustangs. They sure do look purdy though..

(BTW, Baer says this straight out on their website in the FAQ section)

In some of the older pad compounds, when the pads reached elevated temperatures consistent with performance or racing use, the binder (that’s the material that holds the friction material in place) boiled off, producing a gas. This gas would build up between the rotor and the brake pad, effectively keeping the pad from directly contacting the rotor. The holes provide a relief path for these gasses, as do slots, so the pad can once again contact the rotor. Crossdrilling was NOT designed to facilitate cooling.<hr></blockquote>
