				Brake rotor choices... which one?
			 
			
			I'm going to be buying some new front brake rotors and I'm curious to see if anyone has experience with any of these brands (or if it matters).  All of these  are from Autozone, Advance, and O'Reilly. My options are: Beck Arnley: 31.99 Duralast: 28.99 Wearever: 28.98 Bendix: 79.48 Raybestos: 19.99 Wagner: 46.99 Brembo: 38.40

			I work for Beck/Arnley.  Therefore they are the best. Seriously though, we don't deal in inferior parts. They have to all exceed the OE specs, not just meet the OE specs.

			If you can find ten people to get cquence rotors they are not bad.  I got the cross dimmpled and slotted for about 180 for all four shipped from cali to virginia.  If not they about fifty bucks more.  Had them for about six months and love them so far.

			Just get the brembo blanks or the BECKS (i've never heard of them but the guy above recommends them).  OEM replacement and cheap. Since we're on the topic of rotors: Are tehre benefits to drilled and/or slotted rotors? I'm un der the impression that the holes help relieve heat and reduce brake fade but are there really reliability and cracking issues with them?? I've never had a problem but I'd like your input.

			In my opinion, they are not worth it for a street car.  Yeah, they might look cool, and impress your friends, but not necessary for most.  And I have had too many friends use them on a DD and get the cracking around the holes. The stock rotors (mostly the calipers) do a fantastic job at bringing the car down from speed.

			drilled/slotted crack when road racing, unless theyre very very whell made. Napa sells blanks that are made in italy(i have some at home) i would try those or brembo.

			I have the cquence dimpled(not drilled!)/slotted rotors.  We'll see how they do on July 13 at Buttonwillow

			I prefer slotted over drilled as drilled does seem to be more prone to cracking. Slotted gives better initial bite. On the rally car we went with brembo blanks - higher than OE but no holes or slots to get dirt/grime caught up and cause delayed brake response! I think like others have mentioned, for a street car a nice blank rotor from a superior company and good HPS pads from Hawk, and you're set. |

			we have the drilled rotors and they held up fine at thunderhill but I still don't know if I should expect cracking or damage in the future.

			So far I have not noticed any cracking or the like on mine.  My car is a DD not a track car so I know the rotoars are more show than anything else.  But What I have noticed is a sharper intial bite, shorter stopping distance and better brake pedal feel.  I did the SS brake lines, new master, new fluid, Hawk HPS in front, ceramic advance auto pads in the back.  So other than rebuilding the calipers my system was reworked.

			So you're telling me that brake fade or "gassing," as that guy calls it,is no longer a factor in modern (60s+) cars?  I don't believe that for one second.
