Cross-Drilled Rotors?

Post by mikesoob7 »

Hi,

All four rotors on my 1991 4wd wagon warp about every 10K. I do live in the mountains but mainly use the gears to brake on downhill runs as much as possible. I torque them to 70 lb-ft. The rotors I buy are from CarQuest, not from the dealer so there may be some difference there. Still, it seems they should last longer than that. I've been thinking about getting spending the extra money for some cross-drilled rotors to see if they can bleed off heat more efficiently to stop the warping. Has anyone had any experience with cross-drilled rotors?

Cryo-treated rotors seem to be the answer. Perhaps a brake conversion, if your willing to do some work?

so, does mountain driving mean taking 5 people off a cliff?

I go out into the hills all the time, and i've never had a brake fade problem. Maybe im just not braking hard enough... :twisted:

Solid rotors are less likely to have problems than drilled. If anything go with slotted.

scottzg: You've never had brake fade? I have a full WRX swap (have h6 brackets, low on funds for new rotors) with stainless lines and new fluid and I regularly get fade when playing in the mountains.


You guys would have been so proud of me this weekend. We had that huge subaru meeting (we actually hold the record now for the largest gathering). Later in the day I followed a WRX 5 speed slightly modded up the hill. I was on his bumper the whole time! One of the passengers kept looking back surprised to see me 8)

On the way down I led two WRX. After a few minutes I was so far ahead I didnt see the cars behind me. Unfortunatly my brakes started fading and I had to slow down. I was still able to get 7-8 car lengths in about 60 seconds if needed. It was so fun!

The only issue is my Kumho's are now turning to slicks!

I do alot of driving in the mountains and warped my front rotors about every 10-15k on my 90 Sedan. The answer for me was cross-drilled front rotors from KVR Performance and PBR (?) pads.

I've had no trouble with Brembo cryo-treated rotors (that's the brand the cryo place used. Cheap bastards).
