Just took a look at my rally road bolts .. they are indeed the blue tinged zinc ones.

Re: hardware, I bought the Porsche stuff from FCP so I can return it whenever it starts to look ugly

Does anyone have a suggestion on cap screws (bolts) alternatives that secure the rear calipers to the brackets? I'm looking for ones that won't rust quite as easily.

I did this about 2 years ago (killer brakes!!!) but the black oxide cap screws that came with the Rally Road kit are rusting badly. This car never sees snow and rarely rain, so this is car washes mostly that has caused this. I'm not sure if these are grade 10.9 or 12.9 - this is 4 bolts that I don't want to incorrectly spec a replacement.

These are M12 x 1.75mm x 65mm.

I just installed some Rally Road brackets and they are definitely not Black Oxide screws. The bolts are zinc plated high grade steel 10.9 so they must of changed them since you installed yours.

I used VHT Black paint and painted all of the pad springs and polished the pins. At $45 per set I will try this first and see how they hold up.

Wait, the rally road kit comes with black oxide screws? That's a terrible design decision, black oxide has next to no corrosion resistance.

Mcmaster has zinc-plated screws of the same spec. However with shipping it's probably cheaper to call local fastener shops like fastenal to see if they have something similar

Looks like he probably sources them from McMaster. $2 extra per kit to include the Zinc plated ones

I’m gonna order a 10 pack, anyone who wants the other five let me know, will ship them out for a Hamilton

Wow, cant believe a company would actually send out black oxide bolts to be used in BBKs. Check out the EcoGuard line of fastenal bolts. I've used these before with oither stuff and they rock.

PSA - make sure the rest of the hardware is Porsche. These pad springs are Centric and are clearly not coated. Just bite the bullet and pay the P-car tax:
