[@RicardoMartinez-qp8oh]

Have front AND rear set up for 5 years on my GLI MKV here are my thoughts: * Front end would dunk with front calipers only, once i got the rears its a like cougar clamping on a tree. * Skip spacers, they only gave me problems in the long run.( broken hubs, Balancing issues, lack of studs makes it a bitch to mount wheels every time) * 35mm Offset wheels will be needed to clear front calipers. OR.... buy any of the Phaeton 18' wheels as they clear with no mods. ( thats my spare tire) * Skip refurbished calipers and buy used original instead. Reason is calipers are aluminum but refurbished ones use steel pistons instead of aluminum pistons as original. After many heat/cool cycles they would always seize. OR..... save and buy NEW. * constant warped rotors were an issue. Fixed with two piece ones from Racing Brake. Not cheap but worth it. * Loooooonnnnng pedal travel, specially after all four were done. Fixed with TTRS/TTS/TT3.2 master cylinder. Last but not least, brakes pads: *Skip the whole Hawks line up, they suck and will gunk up your wheels and pretty calipers in a day. Red/yellow/rainbow stuff from EBC were not much better. Same goes for Pagid as well. Solution? * Believe it or not the run of the mill BOSCH bite/modulate/last/consistent 99% of the ones mentioned above with 10% of brake dust at 30% of the price. * OR.... ET300, ET500 from Racing brake are AMAZING. Bitches are immortal as i can't seem to wear them down, invisible brake dust and they bite and clam over and over and over with no fade. About the ET's: they have a poor initial bite and will need to be warmed up for optimal use.

Thank you so much

Good afternoon guys, I do have MK5 GOLF at the moment. Can you please tell me which Cayenne model the clippers came from and also which Mercedes ML model the discs came from so that I can pin point it. Many thanks guys.

[@rush4ever1]

They’re called rotor centric rings. The hubs are different sizes. You can see the rotor center isn’t snug. Hub centric rings are for after the rotor for the wheel.

I drive a stock Seat Cupra ST which is basically a front wheel drive golf wagon. It is the sub8 version which comes stock with brembo 4 pot calipers and 370mm discs. Amazing brakes! And come on the car stock.

[@RedsVolkswagenRepair]

If you ran 8mm spacers, do you think the wheel would clear the outside of the caliper? How much wider are these calipers from the center of the rotor fins to the inside of the face of the rim?

Thanks for the video can you tell me can 17inch wheels fit on those calipers?

[@phantom_heart2323]

These look a lot like q7 calipers 🤔 do you think they would work on an s5?

[@Dinur36]

One question, what are the specs of the wheel ? Size J / ET / Offset . And what 18" wheel specs will fit the brembo 18z?

[@erichtisnado1536]

BTW, Cayenne and VW Toreag calipers are the same. You can probably save yourself a few bucks if you can do without the Porsche logo. They have 4 piston and 6 piston versions. Either one is a huge upgrade from the VW single piston caliper. I also read somewhere that the caliper bolt is much bigger on the big brake calipers. I saw somebody solved this issue by using the smaller stock bolts, but using an insert sleeve in the caliper to take up the extra room, so there's no slop. I have 19" rims on my Audi A4, but I kept my stock 17" rims for snow tires. I heard they might still fit. I'm curious to find out for sure. I'm not likely to change out my front brakes when I drive to the snow.

[@mkr1566]

i don't want to use spacers, any help whit wheels? some oem vag 18''

Hi, i have one question. Did the Caliper mounts in front of the wheel hub or behind ?

Is this for front and rear?

[@MrFreakzinho81]

Hey Guys, great channel by the way. Quick questions: (Cayenne's calipers from which year of production). 1- How does this upgrade affect front and back brake bias? 2- What type of upgrade do you guys have planned for the rear? 3- No master cylinder or any other brake components necessary (stainless brake lines, brake plates adaptors, etc..) 4- What type of brake fluid are you guys using, and last questions. 5- The hub centric "adaptor" is necessary to space out the wheels to clear the calipers or just to make sure the wheels are centered? Thanks! Again, love the channel.

[@BoostBrothersGarage]

Thanks!!! I’ll post a link at the end of this comment with all the components you need, model numbers, etc. The brake lines are off another VW and are a direct bolt on, no need for custom stainless one. As for brake bias and rear mods, we are going to run a regular street pad up front and a race of in back to even out the bias for now. The first track event of the year is two weeks from now so we will see how it does, but so far so good. No master cylinder mods needed yet! www.golfmkv.com/forums/showthread.php?t=167209

[@cesarortega6615]

What year Mercedes and Cayenne

[@itstrenttv]

Thanks for the vid I was wondering what OEM calipers would fit. Do you know if the rears would be aswell also would these clear 17"s?

[@BoostBrothersGarage]

To my knowledge the rears do not fit. When running the 330mm rotors you should clear 17’s

[@itstrenttv]

@@BoostBrothersGarage thanks man well I assumed those calipers wouldn't I was more concerned with a big brake kit for the rear that was an OEM from another vehicle

[@ErikRules21]

hopefully someone can answer my question. lm looking to buy the ECS tuning big break kit that don't include the calipers. I want to buy the calipers separate because its cheaper I've been looking on ebay and amazon and l found a few Porsche 955 cayenne calipers but not sure what year they have to be in order to put on my golf R 2013. they have 2003 to 2010. and l can't seem to find the part number on ebay. any help would be appreciated. thanks.

[@MrTorque3]

The hub have 65 mm center hole for original dość brake and the ml 350 discs have 67 how do You Solve that problem ?

[@xkrnxboix]

How would this affect the brake bias (front/rear) after install? Will this also affect the ABS?

[@BoostBrothersGarage]

Should not affect ABS. As for bias, Thomas is going to run standard pads up front and track pads in the rear to help solve that issue. Eventually, the rear may get a BBK as well.

[@SublimeC88]

Did a similar project on my old car Evo 8 Brembo brakes on an Eclipse

[@BoostBrothersGarage]

Nice! I bet that was a big upgrade

[@SublimeC88]

It definitely was!! Front and rear started as single piston calipers and ended with 4 piston front and 2 piston rears.

[@richardanderson9092]

Super upgrade, and happy to see some GTi content. Did you guys do the hydraulic equivalency maths? Physically fits doesn't automatically mean it is all right.

[@BoostBrothersGarage]

Not yet, but this is a well documented upgrade that is apparently proven to work well. But, we will know more when we shake it down! We will have quite a bit more GTI stuff coming over the next few weeks as we are in a race to get it done by Mid April.

[@richardanderson9092]

www.tceperformanceproducts.com/bias-calculator/ Plug your before and after into that and compare. Todd at TCE is real good with brakes. He races at Pikes Peak so he'd probably be dead by now if he weren't.

[@BoostBrothersGarage]

Good stuff, thanks!

[@TSCrihfield]

Needs the Master cylinder changed before it’s finished. Based on the guy I spoke with prior to doing this, he’s ran his track car for about 5 years in this configuration. He explained the pains he had prior to changing the MC so it’s going to get done as well.

[@JorgeMartinez-yp7yv]

Do they just bolt up with the regular caliper bolts or do you have to get aftermarket bolts?

[@BoostBrothersGarage]

I link to a thread that explains what’s needed a few times in the comments, and I believe in the description as well. The factory bolts are reused but a “spacer” is inserted with the bolt.

Will these calipers fit straight onto the Golf carriers or would I need the Cayenne carriers.I'm in the UK so I think you guys call our Golf the Jetta. Cheers guys.

[@BoostBrothersGarage]

I did a quick search and it looks like the GTI and the Jetta (your golf?) use different calipers from the factory. My assumption is no, but you would have to do some digging as I am by no means a VW expert!

[@stuart_wood]

Did you use the original MK5 bolts to mount the caliper? I see there are kits online. Have you got pictures of the inside of the caliper?

[@BoostBrothersGarage]

No pictures of the inside of the calipers. We did use the factory bolts, along with spacers (made of 1/2” copper tubing, 5/8” OD)

[@RedsVolkswagenRepair]

Creation Motorsports makes specialty bolts that have a larger diameter area and a smaller diameter area.

Dem. Binders. Doe. Curious what the weight difference is between the Cayenne and stock calipers? Either way your channel just keeps getting better, keep up the great work gents!

[@BoostBrothersGarage]

Thanks dude! Having held both of the calipers, I think it's relatively minimal believe it or not. The Cayenne calipers are truly massive. I was joking with Thomas about the car doing a front flip the first time he hits the brakes lol.

[@TSCrihfield]

Namesi sorry for the late reply here. The factory caliper is heavier by about 4-5oz. However, the rotors are heavier by 6 lbs. it is a huge impact to unsprung weight which I hope to eventually win back with other modifications. For now, I’ll live with a FWD that pushes a bit more than it used to for a brake that doesn’t overheat like the factory setup did.

[@Namesi]

Wow that's impressive that the Cayenne caliper is actually lighter! You are gonna need all the help you can get with all that booooooooost lol. Keep up the awesome work!

[@BoostBrothersGarage]

Sounds like you just need to make a set of rotors with aluminum hats. Then again, got draw the line somewhere! That time, effort and money should go to the 911 build.
