I've put the info in the comments on one of the fb group discussions and decided to put it here for everyone else.

This is a 13" BBK that is completely bolt on with no modifications except for cutting of the heat shield.

What is needed:
Calipers:
-Mercedes benz 220 s-class 4 piston calipers. Something like a 00 or 01 model s430/s500.
-Here is a link to a current auction.
http://www.ebay.com/itm/DAP-W220-ME...Parts_Accessories&hash=item19f997c73b&vxp=mtr

Rotors:
-2012 Mercedes Benz R-class rotors. There 330mm tall and 32mm thick.
-They can be purchased on rock auto drill and slotted for like 70$ each(something like that Dont know exact numbers) or blank for cheaper. Also available at any other auto parts store as well.
-Yes the bolt pattern is 5x112. The R-class, GL-class, and ML-class all use bigger wheel bolts which allow the rotors to slide on no problem.

Hub centric rings:
- You will need 60mm ID to 67mm OD hub centric rings.
- Reason the rotors will not be centered. Use the rings and then the rotors will be centered thus preventing any alignment issues.

Caliper bolts:
- Mercedes Benz 220 caliper bolts.
- They are different threads than the mk3 calipers.
-link
http://www.ebay.com/itm/Mercedes-R1...Parts_Accessories&hash=item51b248fc5e&vxp=mtr

Washers:
- 4-5mm of washers
- Reason is the caliper needs to be spaced out slightly to be centered on the rotors.


-----The calipers use the same exact bolt spacing as our cars. With the rotors mounted the calipers need to be spaced out a little bit to line up with the rotor perfectly.

-----The stock brake lines and banjo bolts are bolt on as well. I would recommend getting new crush washers and preferably thicker ones as the bolt can bottom out inside the caliper which would prevent it from sealing.

-----The stock backing plate/dust shield will need to be trimmed off or bent out of the way by a good amount as the larger rotors sit father back and are taller.

-----Also be aware that these calipers will not fit on every wheel. They need a higher offset wheel or something with concave disc like a te37 or something like that. My xxr521 +25 18/10 would not fit with these calipers.

-----Thats about it. Everything bolts on like when doing a standard brake job.


Heres some pics.

Installed on 18" enkei nt03




Installed on 17" enkei rpf1.


Some pics without the wheel and with the washers in place.

Prolly not. That will have basically the same face. Would need to go higher and even then im not sure if any of the 521 would fit since they have such a flat disc.

Great thanks for the suggestion and info. Also wondering if I need 4 to 5mm washers or 4 times (x) 5mm washers? If we're spacing out the caliper by 10mm, would it be "safer" to get a bolt that is 10mm longer????

Having never done this "BBK" I would measure out 4mm or 5mm in washers with a set of digital/dial calipers and then put them on. I would then check how the caliper and pads line up with the rotor and if it needs to be spaced more or less by most likely 1mm.

Awesome find! I saw on one of the benz forums that some of their calipers had the same mounting distance as ours but never figured out which ones.

It'd be nice to compare the weight, piston diameter etc of this bolt on kit to some of the aftermarket options.


edit:

(stock) single 60mm - 2827 mm^2

(benz) 2x44, 2x40mm - 5533 mm^2, 96% bigger

brake rotor 26.5 lbs for the 2012 Mercedes Benz R350

I just used 2 washers on each bolt that were from mercedes flex disc I had laying around. Basically just need to space the caliper out enough so it's even with rotors like Steven said.

The calipers them selfs are not too heavy. Maybe about same weight. But the rotor is much heavier but would be able to take a good amount of abuse.

Question, just to clear things up. The 5x112 rotors doesn't need to be modified to fit our hubs, studs? Also, remembering seeing this on the FB page, one can use the 350z rotors too or no. Thanks for finally putting this on SM. FB is so hard to keep track and search.

There is not modification to this kit. Just need the hubcentric ring so rotor sits perfect. The only real work you have to do for this kit is cut the dust shields which is cake. Yea the one you see on fb is a lot different he had to bccut the rotor this one is completely bolt on.

The wheel bolt pattern is unchanged.

No because the wheel studs on the suv mercedes are bigger than the standard ones like the e500 so they just slide on with no grinding or machining.

Id assume you could use the track rotors as well but i dont see the point. And i have never tried.

Might be worthwhile to buy the caliper first, remove the brake pads, mount and test fit with your wheel. I'm not sure that will work though? I have Work Meister S1 with +42 offset that I'm hoping will work with this setup. Pricing items out for me up in Canada this setup is running about $600 with shipping and good components (drilled and slotted plus good pads). Very reasonable in my opinion.

nice find!!! looks like a much better option than the cobra brakes that only have two 42mm pistons iirc that don't end up making that much more braking force than stock. and these look like the pad covers more of the rotor too. what hub centric rings work for sure?

and it looks like you use the Mercedes brake line? but can't tell forsure.

no stock brake lines. I used pics from dubsupras car, which is not fully operational atm. But they are installed on my other friends car with 2jz vvti making 615hp and is a dd.

I used some of the hard plastic hub rings. there very strong and i had to sand them a little bit to get a better fit with an older rotor and the hub. Metal would also work fine and would be more durable. Up to you.

I really want to try these even though I have a Cobra brake setup sitting here already, much more piston on these. I just hope they would fit my Sterns

Pedal feel is normal. Stops like normal when you need to and when stops much faster when you need to. Also won't fade or warp as easy.

Hi SideWinder, where did you get these dimensions from?

My other sports car is an E46 M3 convertible and that car stops amazingly compared to the supra. The front rotor is something like 12.9" I believe and the weight of the convertible is almost exactly the same as the MK3 supra, so I would anticipate with this upgrade that I would or should have the same stopping power as my M3 (fingers crossed). I'd love to find out more stats on the M3 brake system so I could try and replicate or beat it for the supra.
Thx.

When you look on rockauto and search for calipers and rotors, centric (from memory) has a small picture with dimensions next to their item. Our front calipers have one 60mm piston and the mercedes calipers are 4 pots, 2 are 44mm and 2 are 40mm according to the pictures.

You also have to take into account brake torque (distance from the center of the rotor at which the force is applied), and since these rotors are slightly larger than stock that increases as well. With good pads you'll have enough stopping power to lock up the front tires if you want to.

So this is for the fronts of course. besides the Evo rear brembo upgrade, are there any others that would work. i remember seeing a thread that had a list of all the brake upgrade possibilities.

Also... i just purchased some ES2's (TE37 reps) 9.5 and 10.5 18's +22 offset.. I should be good to throw on the benz brakes i would think. they are a pretty concaved wheel.
