Porsche boxster 4 piston brakes (NQSBBK) fitted on MK7 GTi.

[ITGUY]

Yes. Vagbremtechnic has a setup to use brembo's from other platforms to the 340mm rotor.

Thanks!!

For the VW application you want the crossover tubes on the end of the caliper with the 40mm piston and the bleeders on the 36mm end. You really don’t want the bleeders on the bottom end of the caliper.

You're right, I looked at my set and that makes more sense to have them on top. I was thinking about how the fluid would flow through them and which set of pistons would move first, but the 36mm pistons should move first either way.

wow thanks for the drawing it all makes sense now.

so do they make the brackets to use the 340mm disc?

The 986 caliper fits on a non-PP GTI sized 312mm rotor. I re-read your original post and it looks like you're trying to use a 996 caliper. I'm not sure if they can be mounted to a MK7.

Here's the corrected diagram

Lets bring this discussion up again! I purchased everything for this whole kit, except the OP used Apikol brackets. I went to Creation Motorsports out in the UK and purchased their brackets and had major fitment issues. The brackets from CM are carbon copies of the Apikol.

Here's the CM brackets.

Hoping someone can lay some knowledge here, because this definitely ruined my plans.

For clarity...the Boxster has the calliper near the bulkhead...the Golf near the bumper....side of wheel.


The Boxster has the 36mm piston as first contact of leading edge...


Now to use the calliper for MK7 Golf you basically move the caliper around the disc to the front position still on the same side...

This put the 36mm piston as top & 40mm as bottom...


Trouble is now the bleeders are pointing at the ground & the cross tubes are on top...this is not good...…& totally against brake design best practice....

So you have to remove the bleeders & cross tubes & swap them over...as the bleeders must be on top....


Not as straight forward a swap compared to the S3? calipers...however those have no easy pin out pad slots...got to remove the whole caliper...

Those state for MK5????


& personally I would recommend VAGbremtechnic….....another UK specialist...

Did this upgrade over the weekend with the Apikol brackets for Mk5, 6, +7. All you need to do is swap the crossovers and bleeders, and use the m10x1 banjo bolts / crush washers that you can also get from apikol. I personally wouldn't use aluminum carriers, and like the steel ones. In my opinion it's not worth saving a few grams when it's the part holding your brakes onto the car.

Yeah, they do state for Mk5. But so do the Apikol and the CM is a direct copy of the Apikol.

Wouldn't touch anything from vagbremtechnic, since they use aluminum instead of steel. Not really worth saving a few grams when it's the part holding your brakes onto the car.

I got all of the parts for the swap, along with brand new rotors and Stoptech pads. I'm just trying to figure out why I'm having fitment issues.

I did the install with the help of DasGespenst from the Mk5 forum, who has installed a set on his own car. To him it looked like the spindle is the issue. With the Mk5/6 having steel and the Mk7 aluminum.

Or the brackets really aren't the same and I blew the cash on an incompatible part?

What isn't fitting? With the apikol ones the caliper is dead center over the rotor. There's a few places where the bracket is close to the spindle, but nothing contacts or binds. Maybe the CM ones are slightly different?

Really???

Obviously you don't like the aluminium hub carrier that supports the brakes & the wheel bearing either...(as fitted to the GTI/GTD/R etc...)


Or very nice AP racing (& others) big brake kits which use aluminium calipers…..


& don't go buying any fancy Ferrari, lambos etc as most use aluminium brake callipers, brackets etc.....


& just for the record those VAGbremtechnic brackets have steel threaded inserts...

I guess you didn't read - I just fitted the aluminum brembos. Don't mind the aluminum hub either - nice big, chunky, forged piece. But if I'm attaching my calipers with a piece made by a guy in an aftermarket shop - I want steel. Same reason I wouldn't want to use helicoils / threaded inserts / other band-aids. Caliper bracket needs to be torqued to 150 ft/lbs. You do you though.

So you like aluminium..just not done by a "guy in an aftermarket shop"...but you will take steel done by the same guy...
""But if I'm attaching my calipers with a piece made by a guy in an aftermarket shop - I want steel""..


bad workmanship will affect both no matter the material..if the workshop is rubbish it makes no matter if its steel or aluminium..

...…& implying that VAGbremtechnic are "a guy in an aftermarket shop" & therefore bad workmanship is highly defamatory…they are a highly specialist company with a very narrow core focus....& produce way better products than many USA big tuners which usually outsource to the cheapest supplier….

They work with VWracing (& others) & have produced many VAG kits over many years...& they know their stuff...I remember when they first started out...but heh ho I'm over here in the same country as them..you aren't....

The margin of error is a lot more forgiving with steel, since it's yield strength will be much greater. So yeah, if our cars are being the test beds, I'll take steel. Didn't mean for you to get so upset, you put what you want on your car and I'll do the same on mine.

Back on topic: I'm guessing the CM copies aren't exact copies of the Apikol ones, which definitely work on the Mk7 GTI.

I did just about the same thing two days ago to my TDI - except I used Boxster S / 911 calipers. My friend owns a euro scrapyard here in Houston and just gave them to me on the condition that I pull them off myself - ala forklift picture. I had them powdercoated and all is good - stops MUCH better haha. The S calipers use the same size pistons as the normal Boxster, but use a larger and thicker rotor. You have to swap the crossover tube and bleeder screws to account for the caliper being on the front of the rotor for VW vs the back for Porsche to ensure that the smaller piston bites first. The OEM porsche tubes don't actually swap due to casting issues. I had the set pictured made at a hydraulic shop for $20.



Porsche Boxster S / 911 calipers

Apikol Boxster S brackets for mk5/6

B5 S4 Zimmerman rotors (321x30)

Apikol rotor centering rings

Apikol brake line banjo bolts

Akebono euro ceramic pads

ECS braided brake lines

ECS mk7 flush mount spacer kit (absolutely necessary)

Custom crossover tubes

How were u able to do this. Their website says not for aluminum knuckles. I would rather do this then just the regular Boxster brakes. Do u not have the aluminum on your car. I thought all gtis were.

Don't care what you put on your car...slagging of a company...or implying that their stuff is rubbish because they are a small company & they use alu materials...that's what I don't like...your attitude...

Here is a poster on this forum who has RS brakes & VAGbremtechnic stuff on his R ..& he is in Norway....

Also you stated earlier that "Same reason I wouldn't want to use helicoils / threaded inserts / other band-aids. Caliper bracket needs to be torqued to 150 ft/lbs. You do you though."


Steel threaded inserts/helicoids etc are widely use in many applications as they produce a much stronger connection than the host material...& the same with insert (tubes) which prevent deformation through repeated bolt tightening...eg steel sleeve in bolt holes in alloy wheels used in motorsport/rally.

I suggest you understand motorsport & materials engineering before you make unfounded defamatory remarks about people/companies.....
