I'm looking to get some new rotors. Any Successes/Failures I should know about for brake rotors?

I'd really prefer a set of two-piece rotors made specifically for track use.

I've had mine turned once already I'll see if they'll do it again as a temporary solution but I'd much rather get a new set of discs.

I know EBC is junk (see pix below). I really want to send them a nasty letter but I'm just to lazy.

Thanks for the input

 

Well, your first criteria (regardless of brand) might be a plain surface rotor, and your second choice slotted.

 

Go with the Stoptech 2 piece slotted or plain aero rotors front and rear. They are expensive, but nice. No cross drilled. They crack..... obviously.

get some blank throwaway rotors from pepboys or autozone.

 

Usually, the best way to go is to either stick with cheap blank rotors or go with a high quality slotted rotor such as the DBA 4000.



Unfortunately, DBA does not make a two piece rotor for the non-brembo cars, but the 4000 rotor is track tested and very good.

 

if you've already had those dimpled rear rotors turned once.... how many miles did you get out of them... What pads were you using?

 

I just ordered a set of the Stoptech Aerorotors from www.ntechengineering.com he has them for $715. The nice thing about the Aerorotors is you jsut buy the replacment rotor and use the same hat next time.

Not all cross-drilled rotors will crack, it really depends on the quality of the drills and how they were done. There are several cars that come with drilled rotors stock, and other BBK's that don't have problems either. Some of the cheap ebay rotors have issues though so you gotta watch out for them. But personally i'd go with slotted myself...

Something is really wrong with that rotor pictured though, the drills are inconsistent and the slots are very oddly shaped. Did it look like that new??? That's crazy, looks almost like it was done by hand!

 

In my experiecne they only invite problems. Even Stoptech does not recomend their cross drilled rotors be used for heavy track use.

My only complaint is that the replacment rotors cost more than buying blank rotors from centric. I would love to get them for the weight savings though.

 

Carbotech pads.
Centric plain rotors. I never runned cross-drilled at events. Maybe slotted, but normally blanks.

 

Blank rotors from Centric. Cheap. Wear/last just fine.

 

DBA's are good, I use the 5000 series in front on my Brembos and they are lasting with heavy track use...The 4000's should be good also...

 

There is a pattern to the drilled dimples. And it isn't cross drilled just dimpled so that may be fooling your eye.

That rotor may have had 1000-2000 miles on it and about 4 hours of track time. I couldn't tell you if the crack started at the dimple and moved outwards or started at the outside and moved in.

I'll look into the DBA series. Problem is usually there is no OEM replacement for the Non-Brembo brakes.

Those blanks from centric are interesting. If they go bad just throw them away. <200$ a pair means I can have a spare (or two)!

I thought from a racing perspective slotted was superior to a plane surface because it allows the pads to "off-gas", or whatever term is used.

 

This is what I run...

 

That's insane..... 1000-2000 miles including 4 track hours... and they look like that? Jeebus... I must be missing something. Did you get them glowing red and throw them into ice water?

What kind of pads and what kind of bed in procedure did you use? My EBC slotted/dimpled are only in front and I have at least 2-3k miles on them and they look nothing like that. My rears have close to 60,000 miles on the original pads and rotors.... I can't fathom having the rears being turned and looking like that after 2000 miles...

 

That was back in February when that happened, even in Texas it's cold in February. There was snow on the ground all weekend.

My front EBC rotors have been fine up until recently. They are warped now but no cracks, although I haven't looked at their backside. I've traditionally had more problems with the rear brakes but now that I got full on racing pads I think the fronts are starting to fade sooner.

What can I say I'm hard on brakes. I think I push my car a little harder than the next person. I think thats why the instructors like to ride with me.

Any opinion on these?

Hey bro, I just put in an order for the PowerSlot cryo treated rotors. I am still debating on what pads to go with though ... I want something that will work on the street but also not overheat on the track and leave deposits on the rotor surface (pedal pulsation).

I've heard good things about PowerSlots with the cryo treatment. They also have the curved vanes and are directional. I would check them out, they are MUCH less expensive than a 2-piece setup...
