Front Spindle Top Bolt

[BBShark]

Nice brackets, what are we doing?

The brackets are for Brembo calipers. I had to change the rotors to C6 because the other rotor hat offset put the calipers back too far in the wheel. Looked awful.

Yeh, I wish there was a cheeeeeep way to get the stock calipers up/out toward my '89 vette wheels, with 2.5" thick wheel adapter in there...they all lost in space now....like to paint them Gloss black metallic, not that it would show all that much, but with the green car....RED/etc would look like crap....

The rear caliper/wheel clearance was good with an deep hat rotor, but the front was back about 1 1/2 (sorry no pix). Rear:

OK, it took me three months but I finally solved this.

So, since I couldn't find the bolt, I was able to fix this by modifying the bracket and moving the caliper out towards the wheel. Also had to switch to C6 calipers (hub bore machined out).

Tip: I always search googul by the Genuine GM part number.
I think this may be GM 3864119.
