Brembo BBK

[George Hill]

Does anyone have any experience with the Brembo Pista or Club Race BBKs? Just looking for some first hand experience to give some thoughts on the setup.

No experience here, but the first one appears to be a 4 piston, two piece design for HPDE/club racing (older F40 style caliper) and the second is a one piece, lighter weight, 6 piston for higher level racing.

I think one forum member with a red M3 runs the 4 piston caliper.

That is correct. The 4 piston is an old design, tried but true caliper and the 6 piston is a newer design.

If I found the member you are talking about he's running a modified 330 GT kit (which he says caliper wise is the same as M3) but is not originally designed as a "race" application, more of a stock replacement setup.

Don't get too hung up on 4 vs 6 piston design. 6 piston calipers will likely require larger (18") wheels, whereas 4 piston calipers can run under 17" wheels. Manufacturers want to keep the front / rear bias as close to factory as possible, especially since many only upgrade the front brakes. In most cases the total sq in of piston area for the 6 piston calipers will be very close to the sq in area of the 4 piston calipers so you are not really gaining any additional clamping power.

You brake pad choice will significantly impact your braking power.

I run a 4 piston AP Racing CP8350 caliper in the front and a 4 piston AP Racing CP5100 caliper in the rear and it is more than enough brake for my track car.

I am not, I was just replying to Slideways

This is a custom setup so there is going to be more to it than just putting the kit on the car so I am just looking for feedback on these particular kits from someone who has actually used them as far as serviceability, consumables and ease of use are concerned.

[Obioban]

As far as serviceability, IIRC Brembo’s 6 piston requires the caliper to come off for pad swaps— huge downgrade from the 4 piston in that way.

That is one of the reasons why I am considering the Club Race vs the Pista, the race caliper has a spring clip, so no tools required.

Eas steve has been running the pistas on his e36 race car and last I talked to him he really liked him.

I'll get more info this week if I can remember.

Do you run your set-up under 17s? If so, what are your wheel specs?

[Sharocks]

I have an OLD 4 piston GTR setup front.

It's MORE than enough for this car.

355mm rotors is perfectly fine up front and if anything preferable.

My SC car has a 6 piston/380mm combo and it's heavy AF.

I'd go 4 piston and run good pads and fluid and you're GTG.

Yes - 17" wheels. I am running Bimmerworld's TA16 17x9 ET42 square setup. Fits perfect under my E46 330Ci wheel wells. No fender rolling and no spacers required. For track day purposes I do run a 12mm spacer on the front.

You're thinking of the old GT calipers. The Pista is a new design, and the pins are removable so you can swap pads without taking the caliper off.

The Pista is Brembo's answer to the AP Radical. I would be inclined to choose the Pista kit over the older F40/F50-based caliper designs, you gain a world of stiffness. Just double check that the race pads you want to use come in the shapes you need.

Anyone have a Brembo GT 4 piston 355mm kit for sale for the e46 m3?



Also does anyone know if the 4 piston Pisa caliper have better wheel clearance then the older f40 4 piston calipers?

"specifically for the race track".

Sounds like a product that will be a PITA

I have the 4 pistons on mine. Haven't had to change pads yet, but I've had no problems to speak of.
