slotted or cross-drilled for a daily driver??
 

I need to get new rotors for my A4. Which one is more practical for a spirited daily driver? I do push the car from time to time, but am not a track racer. Also, how come the cross-drilled rotors come as OE for many high-performance cars, but not slotted rotors? Is that saying something about which one I should go with?

Thanks for your help!

Go with plain or slotted...
 

if you want to know the good details, do a search.

slotted. the drilled rotors on the jeep are cracking.

ATE power discs work well....
 

Have them on our 30v with ATE pads and have been quite happy. Far less brake fade and more initial bite. Its a nice upgrade for the $$.

Stock.
 

Slotting and drilling only adds cost to the rotors. Take that extra money and spend it on better pads. And make sure you torque your lug bolts to 89 ft-lbs or you'll warp the new rotors in a heartbeat.

I prefer slots to keep a good surface on the pads...
 

helps cause you rarely get the pads up to temp (which maintains the transfer layer) on the street. Slotted rotors also have a little more "bite".

2nd...stock is fine for normal driving..Zimmerman rotors, Textar pads
 

I'll stay away from the overtorque=warped rotors...this was debated a while ago and the consensus was that on our cars, and many other cars - it is not valid that overtorqueing will warp rotors
(on my old Ford minivan, this would happen)

overtorqing isn't the issue...unevenly torqued wheel bolts are the issue.
 

Give me 5 minutes with your car on unevenly torqued wheel bolts, and I'll show you a set of warped rotors.

I don't know who came up with that idiotic consensus, but it's wrong.

gracias...good info....no one brought up uneven torque - just overtorque

Big 2nd. I actually perfer that to the Zimmerman CD's I had before, but EBC Green would be nice to.
