DBA T3 5000 rotor ring fitment on OEM 1LE hats and some track data
I've finally received my DBA T3 5000 rotor ring(driver side) that I ordered to test fit with the OEM hats. I also ordered a Klutch 5-80 lb/ft torque wrench since the required torque spec is only 9.6 lb/ft.
Although the rotors were not listed as compatible with our Camaros, I figured it'd be my turn to be a guinea pig X25 gave me the idea of testing those with my 1LE OEM hats since he had them at some point and his C7 Z06 brakes and our 6 piston 1LE Brembo brakes have the same caliper and rotor sizes (with different hats of course). We figured there is a good possibility of them having the same drive pin specs/fitment and it may be worth trying. https://www.knsbrakes.com/c/car-seri...2FCorvette+Hat Part numbers are as follows: DBA52770.1LS DBA52770.1RS Nordlock M14 washers for front (optional see below) Important :For those who are planning to replace the rotors, please keep in mind that these are torque to yield bolts and it's advised to use new bolts at each service. I used lock washers and torqued them to 90 lb/ft but will also order new set of bolts for the next change. Please refer to guidelines and DO IT AT YOUR OWN RISK! As you can see in the below image drive pin holes matched perfectly and so that I removed the OEM hat to install the DBA rotor ring. And success! Before the track event, I weighed the OEM front rotors at 27.5 lbs and 27.3lbs after that (OEM ring =24.6lbs hat,nuts,bolts, shims=2.7lbs) which means the OEM ring before the track use should be at around 24.8lbs (give or take) DBA ring on the other hand is 23.5lbs, 1.3lbs of rotational mass may not be that much but considering the fact that these cost about the same as the OEM rotors and DBA rotors are known for their durability and rotor life, I figured I can try them. I also don't mind changing the rings on the OEM hat as each new rings comes with new set of nuts. I will go ahead and order the other side and start running them before the next week. Before I decided to try the DBAs , I also considered Girodisc but they didn't offer OEM replacement rings or OEM size 2 piece rotors for 6th Gen Camaro yet. I also found the initial cost of the Racing Brake rotors a bit too much ($1200 for front rotors and $1000 for the rear and $600 for replacement rings). I test fitted them on the car also Before putting the knuckle/caliper bolts I put Nordlock washers and torqued them to 90lb/ft. I had to remove the MRC sensors from its brackets to be able to fit the torque wrench in there (see in the 2nd picture)

This is really awesome. THANK YOU for posting this, I was thinking about these same rings and although the math for these being the same as a C7Z is there, I wanted to see it too! I had DBA's for my C7, and they were great. WOW! That's awesome.
Guess I'm buying a torque wrench too, new tool! Thanks glamcem!

Good news - thx for posting. Since there are no official 1LE fitments specified, how did you go about ordering the right size? Sorry if I am missing something obvious here. Thx!

Yeah, there is no clear way to find that (took me awhile too just to verify brake pads lol)...

Thanks for doing this! Sounds like the price is not much better, but we get an unsprung weight savings. Is this correct?

Very nice. Although not needed from a performance standpoint, what would the correct part be for the rears? That way they would match and thus satisfy the OCD side of my brain.

People seem to be happy with DBA 4000 series (and when matched with ST43s) on C5 Corvettes , lighter car of course but 5000 series are supposedly better/more robust than the 4000s so I wonder how they would do on the newer Camaro.
Here's a good read on Corvette forums for those might be interested: https://www.corvetteforum.com/forums...post1594387817
