Boxster Calipers Hi guys, looking for a pair of Boxster/Cayman non-S calipers for a brake upgrade on my GTI, so I was wondering if I can get help finding them? Ebay is mostly a full set of front/rear for used ones, and the new ones are rather expensive at $400 a pop. 6speedonline doesn't have much, and I've searched Renntech for a bit. Thanks a bunch! |
You won't find much on Renntech. It is a forum plastered with overpriced P-cars and parts, listed specifically to target newbs and parts hoarding freaks. Try joining the Pelican Parts Technical BBS for a more comprehensive listing. You may have a bigger chance of finding what you're looking. I have found that most people on the forum are very helpful and knowledgeable. Your other options are to check out the various local PCA clubs. You can start with the PCA Canada West Chapter and go from there. I get the impression that you are looking for a new set of calipers, which may cost a pretty penny, however, you should aim for a good set of used calipers, hopefully rebuilt or with minimal use. If you want to hunt for a good deal close to home, give the guys at Chris' German Auto a call. I've dealt with them before and they are a super awesome bunch of people. Chris, the owner, is a VERY helpful guy. Another reliable source would be John Walker's Workshop also based out of Seattle. Locally, you can try Pacific Western Performance. (I've never dealt with them but they are a local PCA sponsor.) Ask these shops if they have any spare calipers for sale because often, customers will come in for a caliper upgrade or whatnot and sell their stock calipers to the shop. Good luck! :) |
I didn't mean to give the impression that I was looking for a new set of calipers only; I'm open to both new and used as long as they are in good condition and of reasonable price. Thanks for the leads, I'll be following them up! I got a reply from Renntech; $125/caliper for a pair pulled off a 58k 2001 Boxster. What do you think? Cosmetics don't matter that much to me, as I'd likely repaint or powdercoat them to match the GTI's red rear calipers. |
^ Gotcha. I wasn't sure whether or not you wanted new or used calipers. $125/caliper with 58,000KM or Miles? If in miles, see if they've been rebuilt. If not, lowball a bit. Shop around with the places I mentioned first to get an idea of what the going rate is. Also, post on the Pelican Parts forum and ask what market rates are and also what the service lifespan of the calipers are before biting on them. Good luck! :) |
so cheap man! freaken brake upgrades for hondas cost like a fortune. |
Change of plans... I found a set of four Q7 calipers on the Used Wheel/Tire forum here... So going for this: http://www.golfmk6.com/forums/showthread.php?t=4537 http://i8.photobucket.com/albums/a8/...f/IMG_6442.jpg http://i8.photobucket.com/albums/a8/...f/IMG_6443.jpg http://i8.photobucket.com/albums/a8/...f/IMG_6444.jpg http://i8.photobucket.com/albums/a8/...f/IMG_6445.jpg |
boxster stock calipers are brembos-- they are actually quite amazing! get those if you get a chance |
Way to not read the thread man... I posted that I was having trouble finding the Boxster calipers and ended up with Q7/Cayenne calipers. I know they're Brembos and that they're great, but they're not that easy to get ahold of. I got 4 Cayenne calipers for the price I would've paid for 2 Boxster calipers in similar condition. They're also Brembos. They're six-piston fronts instead of four, and four piston rear instead of two. And they clamp a much bigger disc all around. |

So...just to clarify. Did you get Audi Q7 or Porsche Cayanne calipers? |

Look, I realize that VAG/Porsche is part of the same company but was not aware that the two vehicles shared the same exact part so thanks for the clarification. |

Sorry for the confusion! Quote:
Plus, I want to track my car, so the hugely increased rotor size will help me with heat dissipation and avoiding fade. Pad choice is more limited on the Cayenne calipers though, compared to the Boxster's. I'm pretty much limited to either Hawk HPS/Blue/DTC, EBC Redstuff/Yellowstuff, and Carbotech's offerings. Pagid has the RS29, but that's much too aggressive for me. |

Yup, got my stainless lines from USP Motorsports for a hell of a steal for four! Are you the guy who did his Boxster calipers on GolfMKV? Tooly? |

Did you upgrade your brake master cylinder? If the answer is no, then you need to double check to make sure there is enough fluid being moved to properly work the new calipers. Also, in reality, the bigger rotors doesn't help that much with heat dissipation. You need enough air to help cool the rotors. Depending on the tires you plan on running, brake ducting might be a good idea, especially if you are going to be running at Mission or other brake intensive tracks that don't have enough straight aways for the brakes to cool. |
I've talked to other forum members who are running upgraded brakes on their GTIs, and the consensus is that the master cylinder of the GTI is capable enough to drive the Cayenne brakes to pretty much their full potential. Apparently the ABS system's proportioning valve is self-adjusting, and will make sure there is enough pressure in the system to move the brakes, and is so in control that the master cylinder doesn't really play a huge role in this. I doubt I'll be running R-compound tires, but I'm definitely looking into some sort of brake ducting/open fog grille modification if I track more often/more aggressively. The sheer increase in rotor mass/size would help increase the heat capacity compared to stock, I think. And of course, appropriate pads that can handle the heat - either EBC Red/Yellow, Hawk HP+/Blue or Carbotechs. |
Those brakes are glorious, although serious overkill for that car and a novice driver. The secret is actually racing brake fluid and track pads. Invest in some Motul RBF600. Take it from someone who knows. Another common mistake is to mount the calipers upside down. It's not enough to make sure the bleeder screws are pointed up. You also must ensure that the arrows cast into the calipers are pointing the same direction as the rotors are turning. If not, you must swap the bleeder screws and crossover pipe on the caliper. |

Plus, it's just more confidence inspiring to have such massive brakes to rely on. Yup, I've got the arrows pointing in the right direction as the mounting directions have not changed for any of the calipers, so they're in the same location as they would be in the Cayenne. No crossover/bleeder swapping required for the GTI application. I think this issue plagued mostly the A4/A3 crew with their AWD driveshafts requiring them to change how they were mounted. |
