I'm looking to purchase 2 piece front rotors for my z. Between coleman, baer, wilwood looking for slotted, drilled if possible..what would you purchase. looking to stay around $750. These will be street only.. also what are the weight of these rotors if anyone knows..thanks
Never had any of those brands except for Baer and mine were one piece. However, I was very pleased with the quality of the rotors and the performance.
I bought stoptech rotors to replace my stock ones..they weight alot my accelerating took a big hit. So now I'm looking for for something at or less than stock weight..
My info on brakes that I have personally compiled, all points towards Performance AFX. They use Coleman rotors, are just about as light as you can buy on the market, and they're about $700 for fronts My set I am piecing together uses these in 14" C6Z sizes, and will use Wilwood Aerolite 6/4 calipers front/rear.

What size are you looking for? I can't help but mention that another great option is AMT Motorsport as they have an exceptional two piece, floating rotor option for us C5 guys that uses the DBA 5000 iron rings on their proprietary hats. They are a top quality company with lots of knowledge and have been known to hook up the forum members in the pricing department. Perhaps he will chime in to provide some more detailed specs.
Those would be good race rotors, but I wanna know how much they weigh.
The DBA rings typically weigh more because of the mass added by the unusual vane pattern internally. However, on the track that isn't necessarily a bad thing. Added mass increases their longevity. But on a street car, maximum weight savings are going to gain you the most over all, ESPECIALLY since it is unsrpung and rotational mass.
Of the track cars I have built, I search for a serviceable size that I can use an OEM rotor from whatever on, so when I'm on the street I can run a cheapo OE rotor, and not tear up my expensive a$$ track setup (why I'm going to C6Z specs; more options, more leverage for stopping, and 14" AFX rotors are lighter than the 12.8" OEM C5 ones, but I can run dirt cheap stock rotors in the off-season). You also want to stay away from drilled rotors if you track it at all, as they are significantly more susceptible to cracking than anything else, but that is fine on the street (unless you consistently make hard stops from 120mph+)
The AFX rotor rings are the same Coleman ones used in NASCAR, and are cheap and widely available for replacements. Coleman also offers several different surface patterns as well, not just slotted, drilled, or drilled/slotted, something I'm not sure DBA does.
IMHO, you pay for the DBA name, and their stuff is middle of the field weight wise. AFX is on the low end weight wise of ALL manufacturers. The only rotors I have seen that are lighter, are the J-hook T1's made by AP Essex brakes...but you are talking Gucci money at that point.

Our setup weighs about 2 lbs per less per assembly than the stock solid rotors. That's not a huge amount of weight savings but it's something. The DBA5000 is indeed a beefy rotor, and with the beef you're getting a whole lot of extra longevity. I've had the rings on my car since beginning of 2015. I did a whole lot of racing, TTing, and instructing in 2015 and 2016 (barely ran the car in 2017) and the rings are still on the car and have plenty of life in them. If you're using these on a street car I can;t imagine you'd ever have to replace the rings. Our replacement rings are $200 each.
They're $800 for the pair but I'm still doing 10% off for Corvette Forum members. And I'll ship them for free to sweeten the deal. Just use coupon code "CF racing" at checkout. Please let me know if I can answe any other questions.

Im going to order the fronts this evening...thanks
Payment sent thanks Mark! I will be ordering rears soon!
Thank Jim! Unfortunately I don't have rears for stock calipers. I run my full floating rotors on the rear of my car because I use AP calipers. Not only only that but you lose the parking brake. Not exactly a street-car friendly setup.

Need opinions on 2 piece rotors!
My set I am piecing together uses these in 14" C6Z sizes, and will use Wilwood Aerolite 6/4 calipers front/rear.
