Porsche Brembo 996 BBK conversion

[heinzboehmer]

Anyone have experience with SHW Performance rotors? FCP says they're OE and made in Germany, but I haven't heard of the brand before. Full set comes out ~$250 cheaper than genuine BMW.

So, feeling like I'm missing something obvious here.

The OE Porsche pads that came with my calipers are at end of life, so I ordered new one using the PN in this thread (99635294903)-- which I don't think is wrong, as FCP agrees that's a stock 996 front pad.

The pads that came have the same pad shape in the portion that goes into the caliper, but there's an extra bit of flange up top that prevents the anti rattle clip from being used.

... what am I missing? I'm fine with no anti rattle clips on track, but on the street that'll almost certainly be way too annoying.

Porsche did a part update in 2010 or so to their pads and clips for that generation of brakes. My dad and I ran into that issue 7 or so years ago on his Cayman. This is sort of common Porsche knowledge but we are not Porsche owners in general and this is a BMW website. Easy to miss and next thing you know, you're out $30 for no reason.

Turns out the answer is I need an different version of the anti rattle clip than came with my calipers.

Only came here to say that I just discovered this thread and so glad I did - will be adding this to the list of future OEM+ modifications I'd like to do on mine, this is fantastic. Thank you for such a detailed write up and DIY!

I'm gonna powder coat them. Same guy who did my E36 brakes, I watched and documented the process and the piston bores are masked off.

Last question for now, what's a known to be good source for high temp Brembo decals (black)

Been a while, but pretty sure I got them on Amazon. Seller had high temp stickers in various colors and sizes.

I'm having my roll bar and rear brace done right now, we are using a Prismatic powder and IIRC the color is Spanish Gold. Good point on the color darkening though, I might be able to offset that by doing a little lighter on the calipers. I get really annoyed when colors that are supposed to match clash because they are off by small amounts, so that may be an issue lol.

What color powder coat? If it's lightish, it might darken after some track days (depends on brand and application and a bunch of other variables of course)

I have a set that I'm going to get refinished very soon. Think I'm going to go for cerakote since I don't trust that regular powder coat will hold up to track abuse.

So are you guys taking the mall the way to bare metal, or just kind of scuffing until it's clean and then priming?

TBH I am strongly considering just having these powder coated. If the inside of the area where the piston is remains clear and unaltered/unscored, I don't really see drawbacks to powder coat, but please enlighten me if I'm missing something.

Steel and brass brushes. Scotchbrite pads. Sandpaper. I got them mostly down to the metal and had them painted and baked by a friend at a body shop. It was a pain in the arse. If you can have them media blasted without damaging the piston bores I would do it.

I had mine powder coated, just need to make sure piston area is properly taped off

If fully restoring them I would suggest laser or sand blasting them down to bare metal. The other 996 thread from Tbone lays out the process. He has sand blasted his.

Pretty much have to scuff them up with sanding or scotch pads and get to a layer that would allow paint adherence, paint stripper works just takes multiple passes along with sanding. Use a prep agent once you have them cleaned up and ready for paint to remove any grease or skin oils from handling. Ive never had an issue using high temp brake caliper paint if they are prepped correctly...not a fun process.

[Nate047]

What’s the best way to clean and prep some very dirty calipers for painting? Brake cleaner is barely doing anything lol.
