I want to see what rotors would most people willing to use on their cars, or used! I am talking about vented (286*22mm). People who vote other could tell us what they would use. __________________ Alpina front lip spoiler,ACS roof spoiler,OEM clear rear-side lights,In-Pro blackchrome front indicators,Lummar tinted glasses,318ti.org decalls,Eibach Sportline 45mm/30mm springs,Bilstein Sprint shocks,16mm rear sway bar,front eccentric wishbone bushes,E46 conv.

(IMHO they crack all too easy!) Slots perform the needed duty if you need them. IE gas venting. Neither really help cooling! If cooling is your issue then you need bigger/vented rotors as opposed to eh stock solid rotors like my 95 came with... My .02 bucks worth.

I curently have Brembo drilled and yes, they are a failure. They offer only noise when braking from high speeds, and worse stopping distance. Most probably i'll get the ATE Powerdiscs, i just wanna see other people' experiences. __________________ Alpina front lip spoiler,ACS roof spoiler,OEM clear rear-side lights,In-Pro blackchrome front indicators,Lummar tinted glasses,318ti.org decalls,Eibach Sportline 45mm/30mm springs,Bilstein Sprint shocks,16mm rear sway bar,front eccentric wishbone bushes,E46 conv.

They've been great and drama-free. I'll probably be putting them on my ti next year. BTW, they're called Ate Premium One here in the States now and BMP Design has great prices on them. | | | 08-13-2007, 08:58 PM | #5 | Senior Member Join Date: Jun 2006 Location: North San Diego County Posts: 108 | I had warped stock front rotors on my '96 Active to replace. The price of Brembos were cheaper and carried a better warranty then OEM rotors. | | | 08-13-2007, 10:16 PM | #6 | Senior Member Join Date: Aug 2004 Location: state college, pa Posts: 3,431 | Quote: Originally Posted by ElfinForest318ti I had warped stock front rotors on my '96 Active to replace.

Even though they're a wear part, they'll still replace them if they "warp." Nice if you're trying to figure out a front suspension problem. That may have changed though. __________________ I scream, you scream, we all scream for ZOMBIES. | | | 08-13-2007, 10:28 PM | #7 | Senior Member Join Date: Sep 2004 Location: Manassas, VA Posts: 4,129 | I put on the ATE powerslots They are now called PremiumOne" rotors. http://www.ate-na.com/generator/www/...rotors_us.html __________________ 1998 (July) 318ti, 5-spd OEM Armrest Blaupunkt Heidelberg CD50 CD Player/Compact Drive MP3 Player Diamond Audio 5.25" rear speakers Navman ICN 530 GPS BMWALARM.COM (with comfort settings) after market alarm system Magnecor 8.5mm wires M-Z3 Shifter/Momo Knob Burlwood Dashboard Stromung Exhaust X-brace Racing Dynamics Front Strut Bar Carbonio C.A.I. 17" Rial Rims Vader Seats/Heated/Lumbar Support M-tech Steering Wheel/Front Sway Bar/Front & Rear Bumper Depos/w 6500K Angel Eyes/6000K HIDs Clear Corners M3 Mirrors UUC Light Weight Flywheel/M5 Clutch/M3 Clutch Slave E28 3.46 LSD/Mcoupe Cover/E30 Flanges & Halfshafts UUC S.S.

Work very well for my needs. Once they have worn through I may look into doing the e46 330 upgrade. Edit: personally not a fan of drilled due to the before mentioned cracking problem. Disks with cast holes are supposed to be more reliable than drilled. As for grooved I don't see any great advantage due to the increased pad ware. | | | 08-13-2007, 11:25 PM | #9 | Senior Member Join Date: Aug 2005 Location: Florida Posts: 2,525 | Vented, cross drilled E46 M3 OEM Motorsport floating rotors here... Over 18 hours of track time on them and no cracks or major issues yet. I use standard zimmerman rotors on the rear. | | | 08-14-2007, 07:05 AM | #10 | Senior Member Join Date: Mar 2005 Location: Portland Or Posts: 2,666 | Quote: Originally Posted by mohaughn Vented, cross drilled E46 M3 OEM Motorsport floating rotors here... Over 18 hours of track time on them and no cracks or major issues yet. I use standard zimmerman rotors on the rear. | The problem with the drilled units is there is no warning, When normal rotors start to heat check (Develop tiny radial surface cracks) they still have a few cycles left, when this happens on a drilled rotor they need to be scrapped because the cracks will propagate and throw a chunk off then the shows over. And all of the cars I work on eventually start heat checking if tracked. Sometimes it takes a lot of time because the brakes cool sufficiently,, on some cars they last 1 race weekend (IE T1 cars). I helped trailer a Z06 with about 10K miles on it a few weeks ago, Drilled front cracked and threw about 1/4 of it through the rim tire and fender. 12K in damage to the car because it looped into the wall, he thought the rotors still looked "Good Enough" Dave __________________ Dave - PDX 1995 318ti - Active Black and Tan. 2005 330xi - Mtech 1 - 6spd - Orient Blue/Black | | | 08-14-2007, 02:53 PM | #11 | Senior Member Join Date: Aug 2005 Location: Florida Posts: 2,525 | I agree, I just think there is a difference in OEM "drilled" units from BMW or Porsche vs what you get from powerslot or zimmerman. I don't know if the BMW units are cast with the holes in them, but they seem to hold up pretty well. I see a ton of porsche's and M3s out at the track using comparable rotors. I'm ok with the upkeep and maintenance required. I make sure to totally inspect them when I rotate the tires after an event. Honestly, I'll probably go back to a non-"drilled" floating rotor if I can find a comparable rotor for less. I figure that this rotor was designed to handle the heat put off by a much heavier car, so I don't think I'm pushing the limits of what this rotor was designed to do. But for the extra cost I'm probably not seeing any benefit, why spend the money again? Especially if they have a shorter than blank rotor life span. | | | 08-14-2007, 02:55 PM | #12 | Senior Member Join Date: Apr 2006 Location: dorchester Posts: 700 | ebc turbos | | | 08-30-2007, 08:31 PM | #13 | Senior Member Join Date: Jun 2006 Location: SOUTH Jersey Posts: 1,085 | While my Ti has never been to the track, I do run the ATE powerslots for the 328 (with updated calipers) aside for a lot of brake dust (even from the HAWK HPS PAds) I have had no complaints.. though people do think the slotting looks weird | | | | Currently Active Users Viewing This Thread: 1 (0 members and 1 guests) | | Posting Rules | You may not post new threads You may not post replies You may not post attachments You may not edit your posts HTML code is Off | | | |
