Thread referenced above.

Hey guys, I spend some time on the subaru forms and a friend of mine linked me this thread. People have made up adaptors for the cadillac brembos (which can be had for disgustingly cheap, 130 a side for a complete caliper) and I am curious if anyone has had the same idea for MINI's. They appear to be off of the ATS-V or something similar. They are a 4pot design and made by Brembo, and can be had for something around 130 EACH SIDE off of rockauto. Is this even possible for our cars? I can't remember how our calipers bolton... but if we could make an adaptor and then run like wilwood 13 inch rotors (the 2 piece design) that'd be cool. It would be a *very* cheap BBK with Brembos.

Let me know what you guys think. Give me some input. The part number for each one of the calipers is

ACDELCO 1722586 (LEFT)
ACDELCO 1722587 (RIGHT)

and then I think you have to buy the pins that hold the pads in!

 

Might need to put a bigger brake booster in too...
The stock unit is about maxed out with the stock... It will do many bbk kits, but barely....
The kit might be just a bit too far...
But I guess you can try it....depends on the volume, but I'm guessing, it will need other upgrades.

 

There are calculations for volume of the calipers on the thread linked above. I think they arent that big. I know people run JCW 4pot brembos and the Wilwood DP6 without problems. Maybe these wouldnt be too bad? I might buy one just to plob it on and see how it looks and see if someone wants to make the adaptors if its possible.

Also - doesnt the GP2 master bolt right onto the R53? or only the R56

 

$82 each on Amazon. Man, that is tempting!

 

Those dont come with the pins on the top to hold the pads in but the pins sell for like 9 dollars.

I might buy one and do lots of mock up. I dont have the experience to make the mounting adaptor though :(



Also, these calipers would be mostly for looks. Sure theyd provide better clamping load and if you ran a 13 inch Wilwood rotor lots of stopping power and heat absorbing.. but not as much as a good track setup

 

I am curious to see where this goes

 

I am too. The only problem being is even if we can get the calipers for cheap (lets say 90 per side so 180) and then maybe a set of EBC pads (180 for the set...?) and the rotors.. who knows how expensive those are if we use Wilwood 13 inch rotors, then lines? I wonder if it would even be cheaper than doing like the Wilwood setup from TCE with 12.2 inch rotors or the ones that use the r56 JCW rotors..

 

I'll keep it simple: Don't do it, won't work out for you.

Cross fittings seldom pan out as planned. This one will be one of those.

 

I know I should listen to you.. and I really know I should... but god damn 90 a side for a 4pot brembo is so damn inviting... I might kind of dabble at this project every once in a while.

 

Ok, move ahead on it.

I'm "just sayin"

I get it, price, fun, custom, your idea and all. Nothing wrong with any of that.

 

this is why I like you. among other reasons. How much are the wilwood 13 inch rotors if you dont mind me asking? :p

 

I just wanted to add my .02c. I don't have anything against this stuff really... it's not my cup of tea as I prefer more dedicated designs and all. But I appreciate the thought that goes into these idea. Doesn't mean I have to agree is all.

When you say "rotors" in my world that means 2pc hats and rotor. That translates into about $650pr usually, some a bit less...others a bit more..

 

yeah that price tag pretty much makes the idea of the 13.1 inch rotors with these brembos absolutely useless.

Also, I seriously do take your 2cents into consideration. I was looking for alternatives to BBKs and saw that so I was like "hmph", but it'll be alot of "RnD" to make it right so maybe someone with more of an engineering (with the right tools) backround should take lead.. :p

 

The issue with the MINI is both MC bore size and bias issues.

There are not a lot of things that work correctly with the oe combo. It's a small bore/high pressure system. When paired with the Caddy stuff the bias will be insanely front favored and the pedal feel will be crap. What it will do is severely nose dive with very poor linear feel under you foot...slowing...slowing... wham! Lock up.
