Brake Rotors

Hey guys, now that the new wheels are in and they expose the caliper and rotor a lot more, I'm looking to upgrade my rotors and paint my calipers. After some research I've come across a company called R1Concepts and they have 2 types of rotors that caught my eye.



The first is a zinc plated for rust protection ($119 for 4)

[Rotor #1]



The second option is "E-coated" (I believe this is electrostatic painting) priced at $285 for 4

[Rotor #2]



Which do you think would look the best and which would provide the best rust prevention?
 
Hard to say..I'd sorta lean towards the "E-coated" being more durable but that's just a a guess.



Off topic- I hope they did the cross-drilling right. I know there aren't any drilled rotors that are OK for use on some Chevies (caprices)..the holes aren't done right and the rotors crack. Those are pretty inexpensive rotors so I dunno if I'd trust 'em...a 90 day warranty against cracking wouldn't give me any peace of mind...but that's just me and I know you didn't ask about such stuff :o
 
I've noticed a lot of cross-drilled rotors developing fine cracks between the holes so I was thinking of asking them to just slot them.
 
Although I don't want to contribute to the OT, drilled rotors will almost always form stress cracks... if not immediately, then over time.



Slotted rotors are good if you want that extra bit of bite at the track when your pads are fading... but just be aware that they will wear your pads faster regardless. They do look good though, I'll admit!



If you are tracking your car, a rotor size upgrade will benefit you. It doesn't increase braking force per se, but rather it increases in heat capacity your braking system can handle before fading and other undesirable effects (when combined with high performance pads, of course).



Heh, but high performance pads do usually bring extra dust and noise, so yea :D. There are pads that minimize this and are more street-worthy (and have good bite when cold), yet can be used for the occasional track day. Research is your best bet here... the Stoptech website has a LOT of EXCELLENT info



good luck! And keep us updated (I expect plenty of pics) :)
 
R1 Concept rotors are good. Either set you will be happy with. Now I dont know if you upgraded your GP brakes to 12" brakes. GP's didnt come with 12" brakes up front like the Monte Carlo and Intrigue.



I have drilled and slotted on both cars, both are auto crossed too. This will be the second season and no problems here!
 
I have the R1 rotors on one of my old Lincolns. If I were you I would go with the slotted only as previously suggested. I did have slight problems with the fit, and my mechanic had to do a little adjusting to make them work. I believe all their rotors are Chinese rotors so the quality is not the best, but so far I have not had any problems other than the initial fitting.
 
There are a few guys with GAs who have the R1 concepts, they seem to be happy with them. Last year I went and put on slotted rotors though up front, with EBC Greens, holy ****, it is a night and day difference. If I can afford it this summer I might do a rear disc conversion and put the rear slots on, and put on some Hawk HPS pads all around. Brake upgrades are awesome. Also fun to "illustrate" the new stopping power, if you inform your passenger :o
 
I would stay away from drilled rotors. Will eat up pads like no other and no real benefit over a normal flat rotor for daily driving. Also, hairline cracks can develop between drills rather easily.



You could probably do slotted rotors though. Will still eat up pads, but not near as quick and no fear of cracks. Powerslot is a good name that is well priced.

I recommend that brand as well. Have had them on the front of the GA since last summer/fall and they have made quite a difference.
 
I replaced my rotors with OEM type Brembo replacements last year and they still look as good as the day I mounted them. There is no rust or corrosion of any kind anywhere on the rotor. The Mustang is my daily driver and they see all kinds of weather. I got them from the Tire Rack...



 
I found a set of rotors that are exactly what I've been looking for. Very resistant to rust and not cross-drilled.

Black-Dash Disc - the new Black-Dash Discs have a new super quiet slotted design and carry a brand new EPF black coating system that gives the best corrosion resistance ever. The new coating is really a milestone in brake disc corrosion protection. It creates a black gloss finish on the rotor which wears off in the area contacted by the pad and is guaranteed to stay on the remaining areas of the disc for a minimum of two years up to five years. 480 hours salt corrosion tests that we have conducted have proved these results.

The only thing I worry about with those is, will the brakes break in properly if they have to wear off the coating first?
 
I have EBC rotors and Hawk pads and I really like them. Mine are slotted and dimpled. I would stay away from drilled rotors.
 
I would also vouch against cross drilled rotors. I have them installed on the civic and while I do notice an increase in performance, I attribute this to the KVR CF pads more so than the KVR cad plated cross drilled rotors. If I had to go back in time to when I placed my order, I would choose either slotted, or Brembo blanks.

There is a lot of truth to the surface area issue of cross drilled and slotted rotors though.



you'll notice greater benefits in using a high performance pad, over a high performance rotor.
 
You also mentioned caliper paint. I've used some G2 red caliper paint. It works pretty well and even chlorinated brake cleaner doesn't mess it up.



For rotors, I'm getting some good results with Brembo sport slotted fronts and stoptech slotted rears. The Brembo sports are yellow zinc plated; hopefully that will be fairly durable.
 
I got my brakes from a VW aftermarket distributor (ecs tuning) and they slot/zinc plate then resell the Brembo sports. I run them with Hawk Ceramics and OMG! do they bring the dub to a stop.

I also have Powerslots on my old GTI and Mintex pads, and that's a track car. Powerslots are excellent rotors for the price. I'll also 2nd/3rd/4th the 'slotted over drilled' conversation. IMO, people that buy drilled rotors do it because it "looks cool" and have no idea about the performance aspect.



I'm currently saving up my money for some cadmium-plated, cryo-treated rotors. :grinno:
