I agree with you 100%. Thanks for bringing me back to my senses.:thumbup:Palantirion said:Good price, possibly even authentic, BUT you notice no calipers are included. If you are not changing the calipers, you're pretty much wasting your time. Maybe the rotors will take 5-10 feet off your 100-0mph distance, but that doesn't add up to must in daily driving. Just buy yourself a good set of pads and keep you stock brakes, or upgrade to a real front BBK - from StopTech.
-Very interesting. Makes sense.VCOUI said:This is true, however it depends on the rotor and driving conditions. I had 'Big Reds' on my Porsche Track car and I used factory 993 Twin Turbo rotors that have more holes than most cross drilled rotors I've seen. They did developed hair line cracks on just about each and ever hole from all the racing and the racing pads. For regular street use, that is less likely to happen with a rotor like the Zimmerman with far fewer holes and there for more space and material between each hole. Not saying that it's impossible, just less likely. I had Zimmerman Cross drilled rotors [just like the ones mentioned above] on the rear of my Porsche track car and they didnt have problems with cracking like the fronts did. [granted the rear does less braking.]
-Good point. I was thinking of StopTech's slotted vs. Brembo's (Dinan's) cross-drilled. I wouldn't buy cheap brakes regardless of their configuration!VCOUI said:My only hesitation with slotted rotors is be sure you get them from a reputable source and manufacture. Many people just machine slots into standard rotors that weren't designed for it. To be honest, when it comes to evacuating gases, the slotted rotor works just as well as a cross drilled. The reason for crossdrilling in the first place was for weight reduction, not gas dispersal. Porsche was the first to do this with the 917 back in the 60's and it was all about reducing unsprung weight. The gas dispersal was just an extra added benefit.
Hmmm, yeah, used brakes, I think I'll pass.AZ-528i said:
For what it's worth, I would think twice about anyone who offers a 30 warranty. Standard factory warranty is 12months or 12,000 miles. Problem is, they have machined these themselves and therefore voided the factory warranty.AZ-528i said:
