I’m not sure the caliper choice matters that much to me.

I think which caliper is more a matter of the hydraulics, I imagine your guy will know which one will work best.

Let’s go with whatever’s most readily available and cheapest ;)

Hey guys,
Scott has a prototypebuilt to handle the C7Z06 or 16+ ZL1/CTS-V3

Additionally, the 5 lug hub works for our spindles if someone wants to convert from 6 lug.

will try to post as many pics to show process to adapt bracket to TBSS spindle.

Scott used the 5 lug blazer hub to prevent from having to drill the rotor hubs (which we will have to do).

Scott’s description of work

The way the spindle casting is sort of "wrapped" around the bearing I wanted to leave those corners in there, they are for support of the structure obviously. Arguably they may not serve as much purpose and planting the adapter flat against the bearing bolt bosses may be possible but I think it would compromise the spindle further than needed. So keeping the bracket back some (approx 1/2 inch) is what I decided on.

The back of the spindle he used laser cut washers .25” each.

So you can see how much needs to come out on the upper area..imagine taking it all the way down flat ! nope. You`ll see sharpie marks here and there those are reference for the future cuts.

So cutting the original caliper mounts off is pretty simple

See that casting mark?
conveniently it sits about .480 above the bearing bolt bosses...we can use that as a guide on how much needs to be removed

here is the bracket peeking around the fresh cut
it`ll need some clearing for the stand off

Upper mount
lower mount...you can see that sharpie mark is still there barely and only a hair of clearance.

With the bracket removed and flipped to the front and some bolts and washers to show placement for the reliefs, I marked them for cutting. Need an end mill, band saw, and grinder for this part

So as you can tell, not an easy setup.

but there is a plethora of brake examples you can use

Scott said these would be the options

Caliper hat depth makes differences
Next I would need to cut and lathe the stand offs for the caliper...these are dependent on what brake you`ll use.

each brake family has a different caliper hat depth
CTS-V2/12-15 Camaro ZL1
CTSV3/16+ CAMARO ZL1
Camaro SS

All of these would need the hub register matched to the rotor (if required) and the 6 bolt pattern drilled into them
  • 2009-15 CTS-V stock rotor w/ center hole opened
  • 2010-15 Camaro SS & ZL-1 stock rotor w/ center hole opened
  • 2016-current Camaro SS w/ C7 z51 rotor
  • 2014-19 C7 Corvette JL9,J55,J56 & Z07
  • XTS and ATS Brembo Cadillac w/ appropriate C7 rotor
  • 2016+ ZL1 & ZL1/1LE
  • 2016+ CTS-V

Final pics
NOTE: not powder coated etc for final product.

See Bigbrakeupgrade.com for more info of the blazer setup.


Not sure community interest -
My own logic, I’m going for the 16+ CTS-V3/ZL1 setup - same weight cars
15.35” 2 piece rotors
Silver ZL1 calipers are cheaper than the red

Hey guys,
So I put the updates for the prototype on another thread

got a pic of the AWD boot to the back of the spindle? If not, anyone got a front axle they can send me, I have another spindle/knuckle to test.

See attached pics of c7 z06 and 16+ zl1/CTS-V3 calipers on the trailblazer spindle.

Hey guys,
Seen lots of posts, and spent lots of time, trying to use the GM parts bin to source performance brakes.
Talked with Scott from BigBrakeUpgrade.com about building a kit using the CTS-V3 vs CTS-V2 brakes. Scott has already built kits for many other models.

Need some data to gauge interest -
  1. How many people are interested in better stopping power?
  2. Aesthetics - do you want bigger brakes for larger rims 20-26”. The CTS-V setup uses 14-15 inch rotor (2 piece rotor for front)
Calipers sourced by individual - factory caliper colors include black, red, yellow, gold, burgundy

tbss's are very heavy. anything that can be done to help the stopping power will help. rotor diameter should not be a problem since they came with 20" wheels. thanks. VERY INTERESTED!!!!

Cool.

been working on rear brakes setup w ZL1 calipers/rotors

anyone got an axle removed that can take some measurements ?

Would love a double check of another’s rear axle measurements:

Rotor hat depth = 3.34375”

OD Axle flange = 81mm or 3.1875”

RE: Axle flange to backing plate flange

D6701175-F1CF-4C46-A02F-56FCA5A30879.jpeg

1) Backing plate to back of axle flange is 2.125”
2) Axle flange thickness is 5/16”
3) Backing plate to axle housing is 3/16”

Total is 2 & 9/16” = 2.5625

pics of hat depth of stock-ish rotor

Sorry I’ve been slammed at work, I’ll try and get some measurements on the front axle boots. I’d love to this kit actually work out.

But I can honestly say it doesn’t look promising for AWD. If it will clear it will be very close.

Will the CTS-V3 fit on the TBSS? I don’t see anything that shows if they are a good fit or not.

Either way, I’m definitely interested in a big brake kit

Hey guys, new update.

Scott has my ZL1 front rotor hubs drilled for the TBSS hubs.

attached the pics for your viewing pleasure.

Awesome work! I thought you were insane in the first few posts. My apologies!

This is now a bolt on ready kit if I have the rotors and calipers with the exception of having to drill the rotor hubs?

Yes sir, stay tuned!

Many would argue my my sanity with such a lofty goal 😁


Scott is awesome, and has been pretty busy. We had discussed bracket design for C7 Z06 iron rotor setup (cheaper but smaller rotors, but larger than Baer).

Brackets, spindles, and ZL1 rotor hubs, arrived late Thursday. Cant wait to assemble the conversion. I’ve already purchased a full set front/rear 16+ ZL1, calipers.

Still have caliper work to do -
Swap the bleeders, and crossover tubes, get braided stainless lines created to adapt the ZL1 caliper.
Currently installing a FSR Radiator, PCMofMC dual eFans w HD SPAL fans, and has been taking my weekends (didn’t quite bolt in).

My hats off to Scott -
