Porsche Brembo 996 BBK conversion

[Hopalong604]

Hi everyone! Does anyone have BBS LM’s with the 996 BBK conversion? If so what size and offset are you guys running? TIA

Just finished with these. I sanded off the Porsche logos with 1000 grit, put decals on, VHT clear over it. Not perfect but it passes the two foot test and they’ll be covered in brake dust soon enough anyway. The calipers came disassembled so rebuilt with the Girodisc seal and boot kits. I used brake fluid as lube and pistons went in nicely for the most part. Couple were more difficult but they seem smooth now.

Boring black but IB is enough color for me

F: 19x8.5, ET +32
R: 19x10, ET +25

No spacers on front or rear

Okay, I swapped from Bremo metallic pads to the recommended Akebono pads with new shims and the front still squeal right before you stop (slow speed) Is there something in the calipers that could be causing the sequel? I just want to know what to check next or do i just need to give it time? (about 100 miles since replacement) Thanks!!

Anyone have corroded / stripped threads on a caliper and if so, how do you fix it? Just a M10 x 1.0 tap? I’ve never had to use one before. About to install the last caliper and the brake line won’t go in, first thread or two is dead.

edit: miraculously managed to thread it. Good luck with that next time you have to change the brake line, future me

It's inherently going to always happen. The brakes oscillate. I posted a technical bulletin about it in from Porsche. I advise you read it.

The "fix" was throwing pads at the car. The last one I replaced Akebono with Brembo. Porsche has multiple OE manufacturers for pads.

I’m in the process of rebuilding some 996 f&r, where are you guys getting new front and rear piston sets from?

I see rockauto has the seals kit

I think you can get Brembo pistons from places like HRP.

Rockauto sells Centric seals, which have some inconsistent tolerances. The kits also do not include the boots, and you might as well replace them while you're at it.
I got the seals and boots from Girodisc.

Unless they're corroded or damaged, pistons tend to last a long time if they're stainless steel or titanium. If you're just rebuilding them to refresh them, inspect the pistons and throw some seals + boots on and call it a day.

StopTech pistons aren't bad and are readily available. I don't know pricing for Brembo pistons but I would guess they aren't cheap.

Yes, pistons are hard anodized. They shouldn't need replacement unless they're not smooth.

A word on boots - they're not that important. They're important if you want to get 100k out of the seals, but if this is a track car where you're rebuilding seals every year or 2 or if this is a lightly driven weekend car, you actually don't even need boots, let alone nice new ones. You can absolutely reuse old ones. They'd have to be really falling apart to not provide protection from the elements.

Doing this conversion as my quarantine project, and I ordered two rear crossover pipes. However, despite ordering two different part numbers, I received two identical pipes. Can anyone confirm which one of these is wrong?

Titaniu//MI just had the same issue as you. Ordered the same part numbers which i thought would be a left and a right but I got two of the same side. Were yours mispackaged or did we both order the wrong part numbers?

[Arith2]

Give me your caliper part numbers and the vehicle they're from. I absolutely need to know the vehicle because the parts catalogue can be a nightmare. I can attempt to check with my parts department on Monday. Not sure how much help they'll be because generally lines like that aren't sold through dealers. It's worth a shot.

Nice exactly what I did.

Mispackaged. Only way around this issue I have found is to physically go down to the dealer that has the parts in stock and inspecting the lines in-person.
