Really liking the pictures. The Brembo's are nice! Also like how they match the background.

Looks killer man, looking to do this soon myself.

can I make love to your car?

It looks incredible. Keep up the good work.

So sick....definitely one of the nicest Verts on the boards...color/wheel/bbk combo is just killin it!!!

[Rendezvous]

That looks great

You do not swap calipers side to side. Porsche engineers intentionally located the smaller piston as the leading piston when the car is rotating forward (both front and rear). When you swapped the calipers (Left to Right), you now have the LARGER piston leading. That's very bad for pad wear and will place undesired clamping force across the pad. The location of the caliper axially about the rotor does not matter when it comes to the application of braking torque, only the placement of the bleeder valves and only for maintenance. They should be located at the top-most portion of the caliper when placed so that the bleeders work efficiently. This is why the bleeders are swapped, but NOT the calipers themselves.


He's right about the application and the idea, but swapping calipers actually reverses this logic and places the pistons in the wrong order.

Examine your configuration again (wheel/rotor removed, that 28mm piston should be the lower of the two (the 30mm piston is at the top when in a trailing design). You probably won't be able to determine that by eyeballing it, 2mm is too little for our eyes to determine unless you've seen a LOT of these.

On the Porsche, with a leading mount, the 28mm piston is on top and the 30mm piston is on bottom. Now rotate the caliper to the rear - notice how the orientation of the pistons is still correct for a trailing design? Now.. in your mind, spatially swap that caliper to the other side and you now have an INCORRECT ORIENTATION. The rotor is coming into contact with the 30mm piston first in a forward rotation if you swap the calipers left and right. Whomever told you this gave you patently bad advice as it sounds like they read some marketing material but lack a fundamental understanding of caliper design, three-dimensional spatial orientation, or drive in reverse the majority of the time. Choose one, but either way, I would swap those calipers back to their correct locations ASAP.


Nice rear rust ring, mind measuring that to see how much of the rear pad isn't covering the rotor contact area? What pad part number did you go with in the rear?

The larger piston is located on the same side of transfer tube. Since I swapped the calipers from side to side, the OLD transfer tube area is now at the top of the rotor trailing the smaller piston. So in forward momentum the smaller piston is making contact first and the larger is making the contact second the way it should be.

Now, if you were to swap to RacingBrake or PFC 2-piece rotors and add some ducting, the performance difference is worth discussing, but then again.. the same goes for stock.

Braking is very similar to the ZCP setup, but that is a superior setup compared to the non competition package M3. My brakes were original and needed to go, so upgrading from the over due, stock caliper and rotor setup to the ZCP setup was much improved, but that's expected.

There's nothing not worth discussing here. I don't need two piece rotors and ducting for street use. Hell I don't even need these brembo calipers, but I wanted to go with something more aesthetically pleasing than the oem M calipers.

Thanks, yep I say it all the time, full grey interior is terrible and even worse on a grey convertible, but cutting the black in there was necessary. Glad you like it too

Gotta thank Martino Auto Concepts in Long Island, NY for that one.

Thanks a lot. We happened to pass by it looking for a place to shoot and seemed fitting.

Awesome, shoot me a pm if you have any questions, hopefully I can help you out.

Thanks Benjo, I didn't get your volks, but I was determined to get a set lol.

I was informed by intelone as to the history of those calipers - it seems they were swapped originally, and you simply swapped them back to the correct side(s). Good catch on your part, but it should be noted in the thread that it's not correct to swap calipers left to right, only the bleeders/crossover lines to keep proper top/bottom orientation since the M3 is a trailing design vs. a leading design on the Boxster S/Cayman S.

Still, you have that mean rust ring as well - I'm working on a solution, but it doesn't look terribly promising.

The transfer tubes can't be replaced top and bottom on the same caliper. They are pitched a certain way that only fits on one side of the caliper. If you take the transfer tube off you can't simply swap it with be bleeder valves. It HAS to go on the other caliper. We installed the brakes on our friend's E46 non M and he came in on fanatics and schooled us on it. I had this set of calipers sitting in my basement at the time so I swapped them accordingly one night and came to the discovery that the transfer tubes only go on one way.

That's correct, the transfer lines are R/L & F/R-specific (for the C4S as well, actually, though some calipers they are not -- oddly). The inboard caliper's line fitting sits further out than the outboard.

It still confuses those considering an installation to state that the calipers are swapped side to side, though, and as written, it's still just as confusing for those who don't understand what a primary, secondary, and even tertiary pistons are for. I received several questions about it, one referencing your thread alone, which is what drew my attention to it in the first place.
