My apologies if already covered (pretty sure it has been), but I couldn't find the thread.

In the middle of a brake conversion. I'm using a complete Brembo brake set-up from a '17 SS (pads, rotors, calipers, and new brake lines from Technafit). The vibration weights on the front pads are hitting the stock steel wheels. I have a set of 18" Holden wheels with a slightly larger offset which will be mounted.

Will this work or do I need to switch to a pad without the weights? I thought I read somewhere someone did the conversion and had to switch to a pad without but can't find it now. :roll:

Update - test fit the Holden wheel, still no good. Would it be out of the question to just cut the weights off? Or would that lead to vibration?

You have 2 options--cut off the dampers on the existing pads, or obtain "correct" pads (FMSI spec D1001) found on 04-07 CTS-V or G8 GXP).

Cutting off the weights will not cause "vibration" per se--they weights are mass dampers designed to reduce the tendency for brake squeal, which in reality is vibration>>>sound.

To me, the more important question is whether the Holden wheel clears the (front) caliper without a spacer. Once the existing pad is modified or replaced by D1001, the radial clearance should be OK, but the back of wheel spoke to caliper body needs to be checked, too.

Try this--remove the pads, install the wheel, and check the spoke-to-caliper clearance. If you do this, just be sure you DO NOT step on the brake pedal before re-installing the pads!

Hi Bill,

Looks like there'll be room for the calipers. I'm pretty sure I'm going to cut the weights off and see how it works. Worst case I get replacement pads. I'll double check the clearance once everything is put back together and report back.

On a side note, the Technafit lines fit great!

Thanks

Did the PPV steel 18" wheel actually clear the Brembo calipers and only the little "vibration dampers" on the pads was hitting?

G8,

Yes, the wheels cleared once the dampers were cut off.

I responded to your PM.

For anyone else contemplating the available options, there are a number of threads that discuss this in a fair amount of detail--here's a quick & dirty recap.

Brembo upgrade using Gen1 CTS-V or Zeta sedan/Camaro SS brakes:

CTS-V-1 Sigma (04-07) front & rear (4-piston calipers) - must "flip" rear calipers by swapping fluid transfer tube & bleeders

CTS-V-2 Sigma 2 front is 6 piston but will work with correct rotor

Use GXP, Camaro SS (10-15) or SS sedan 355mm front rotors and 15-17 SS sedan 360mm rear rotors
NOTE: the 360mm sedan rear rotor is the only option, since it has the correct size park brake drum diameter to fit PPV

For 6-piston front, use CTS-V or ZL1 370mm front rotors

If using CTS-V(1) or GXP front calipers, the mounting fastener threads are M12. PPV uses M14 fasteners, so it will be necessary to accommodate the size difference:

Option 1 - install bushings in the knuckle mounting holes and use M12 bolts to secure caliper to knuckle
Option 2 - drill & re-tap the mounting ears on the caliper and use M14 bolts to secure caliper to knuckle

I prefer & recommend Option 2.

The alternative to CTS-V/GXP for a Brembo 4-piston upgrade is to acquire calipers from either 2010-2015 Camaro SS or 2015-2017 Chevy SS sedan--it's direct bolt-up, other than trimming the rear rotor debris shields (for 360mm rotor).

There has been a more recent discussion about using Gen6 Camaro SS front (Brembo) calipers with the stock PPV 345mm rotors.
