Baer Brake *Rotors* (not hats) replacement

[N40GL]

I'm hoping someone can help, rather than wading through 20 years of posts on this site.

Does anyone have the part number handy for the DBA* rotors that match to the Baer brake hats that Kenny Brown used on his cars? I know the Baer rotors warp easily, and the treated rotors from DBA are the solution, but I can't find my receipt from the last time I ordered them.

Thanks in advance for the assistance.

A dozen years ago I worked with the good folks at:

KNS Brakes
120 Woodwinds Industrial Court
Unit E
Cary NC 27511
919-388-3837

and purchased 2 sets of the Front, Cross-Drilled and Slotted Front Rotors as well as the Cross-Drilled and Slotted Matching rears

I bought DBA rotors from KNS

Hi Guys,

Thanks for the information. I've got a dialogue going (email) with KNS. While those part numbers weren't recognized. they are looking into what the current replacement options are.

Given that these are getting harder to find, I think I'll order two sets of front and rear rotors this time around, and put one set 'up on the shelf' for later.

FYI: KNS has a new phone number: 919-420-0021
AND: https://www.knsbrakes.com/c/home

-----------------------------------

Just to put all the information in one place for someone who needs it later (whoever owns the 'list of parts' on the board can add it in to there):

DBA Part No. from KNS:
52102.1SL, and 52102.1SR.

Old Baer Item Nos.:
6910260 (14.00x1.25 L 12x8.50)
6920260 (14.00x1.25 R 12x8.50)

Even older Baer Item Nos.:
6910264 (2-pc L 14 x 1.25 SDZ EXT+ 12b)
6920264 (2-pc R 14 x 1.25 SDZ EXT+ 12.b)

Quick Update:

DBA rotors are no longer directional. That makes the part number 52102.1S (per DBA and KNS Brakes).

More data for nerds:
MM Wheel Bolt Circle: 5 x 114.3mm
Center Bore: 70.5mm
DBA Rotor Bolt Circle: 12 x 8.5
DBA Rotor Size: 14" x 1.25" (355.6mm x 32mm) (NOTE: there are eleven 355mm x 32mm DBA rotors but only ONE that's 355.6mm - part no. 52102.1S)

The only thing I don't know is the replacement hat depth. Baer part number 6140040 (hat only) is 0.400" (10.16mm) but that seems shallow. I've got to measure the car.

I have the single piece version on front of of my trilogy with the Zack and Jerry big brake kit(basically the same thing as Baer) for over 130,000 miles and I abuse them. I’m about to put the 5th set of pads on the front and the rotors are still in good shape…. By far the best rotors I’ve ever used, but they are expensive, at the time I put them on they were $300+ each.
