850 Turbo Wagon Cross Drilled VS OEM Rotors Opinions??

Cross drilled rotors look cool, and they do "de-gas" the brake pads (as well as provide better heat dissipation)

Unless you are racing, or towing a heavy load, cross drilled rotors will not provide a noticable difference. The do make more noise (like air fluttering about).

A good quality rotor would be just fine, but as mentioned, if you take the car to the track, tow, or drive like me on a daily basis ;), then cross drilled is fine (plus as mentioned, they look cool through wheels that show them off).

Do they wear pads quicker? Not so much with chamfered holes, but the rotors may crack between the drilled holes. All drilled rotors are not created equally either, the pattern that works best is a radial spiral, and are directional to some extent (left side, right side).

On my race car, I use a solid rotor, I am not exceeding 1200F for it to be an issue. Slotting is another method for de-gassing, but doesn't offer much in the way of aiding in cooling.

I've been completely happy with standard design rotors on my 850. Unless you drive at near rack track conditions I think that the drilled rotors are a solution trying to find a problem.

either, the pattern

way of aiding in

I installed cross drilled rotors on my 850 a while back - around 195,000 miles......

The best reason to use them - they don't cost any more than regular rotors - is that, according to my mechanics, they've never seen a warped cross drilled rotor.....! Heat dissipation is the most serious problem in this arena and that recommendation was good enough for me. It may just be "subjective" on my part, but I find the brakes to be smoother and very strong with the new rotors and pads in place.....

x drilled and slotted rotors l@@k cool...and, they keep a bit cooler also... a little bit of performance pick up here, a little bit there...soon, it adds up...imho
