Thanks!

Yes, I will post up once I have got an issue with handbrake sorted [rear discs sent were F3x part # ending 6797 600] and correct part number is last 3 digits 598.

Fronts - were items 9, 10, 11 and 12 on the attached
http://www.realoem.com/bmw/enUS/show...diagId=34_1992 Wrt pads, you can go for item # 8 and I got a deal on a set of F8x MP front pads 34112284765.

Hi BP,

Did you get all the hardware used?

I was compiling all parts to do the conversion:

With brand new parts, to change front calipers, front disc protection plate, 4 drilled M Performance discs and pads:

Code:

1	Caliper housing left			34 11 6 799 469			614,83 €		614,83 €
1	CALIPER HOUSING RIGHT			34 11 6 799 470			614,83 €		614,83 €
4	Hex Bolt (chrome-free CR(VI))	M12X1,5X43 ZNS3		34 11 6 772 117			3,17 €		12,68 €

2	Brake disc, ventilated, w/holes, front	370X30 		34 10 6 797 603			229,85 €		459,70 €
2	Inner hex bolt	M8X14 		34 21 1 161 806			0,90 €		1,80 €
1	Protection plate left			34 11 6 872 081			30,94 €		30,94 €
1	Protection plate right			34 11 6 792 238			30,94 €		30,94 €
8	Hex Bolt (chrome-free CR(VI))	M6X12-Z1-8.8 MK		34 11 6 772 886			0,63 €		5,04 €
									0,00 €
1	Repair kit, brake pads asbestos-free			34 21 6 876 422			141,74 €		141,74 €
1	Brake-pad sensor, rear			34 35 6 792 292			28,49 €		28,49 €
2	Brake disc, ventilated, w/holes, rear	345X24 		34 20 6 797 598			144,85 €		289,70 €
2	Inner hex bolt	M8X14 		34 21 1 161 806			0,90 €		1,80 €
									0,00 €
4	Brake-pad paste (BMW Group)	3G		83 19 2 158 851			0,75 €		3,00 €
									
									2 469,76 €

=> 2469.76€

M Performance Big Brake Kit in red:

Code:

							Leebmann24		Leebmann24
1	Retrofit kit, sport brake, red			34 11 2 221 445			1 749,00 €		1 749,00 €
2	Brake disc, ventilated, w/holes, rear	345X24 		34 20 6 797 598			144,85 €		289,70 €
									
									2 038,70 €

=> 2038.70€

It's 400€ cheaper with rear calipers on top of the rest!

Even with used front calipers, Red BBK is very well placed price-wise.

But MPBBK is in red, yellow or orange and my car is EBII...

BiscottiGelato · 02-26-2016, 01:11 PM

That was my argument. The kit seems like a bargain given that you can sell your blue callipers back out.

Calipers were bought used but in fact were brand new.

Pads, protection plates, discs and wear sensors - all new.

I also added braided steel hoses and RBF - came in much cheaper.

Did you have significant discount on new parts?

Bee Pee, you're talking about the discounted 370mm calipers in particular, right? I used the same source as you, they're less than half the price of new!

Bee Pee · 03-01-2016, 03:31 AM

These look good value for anyone stateside looking to upgrade - a pair of 370mm calipers and pads for 620 bucks...:-

http://f20.1addicts.com/forums/showthread.php?t=1231761

Also the thread has a great photo to illustrate the difference between 340mm caliper [top] and 370/380 MP BBK/F30 msport/F8x std front caliper [bottom]

Bee Pee, I've just received a set of calipers from this seller. Took a while to get to the US from the EU...

The part numbers on these calipers appear (I scanned the bar codes on the back) to be 34116799467 and 468, which appear in no ETKA.

Did you verify the part numbers of the calipers you installed?

Thanks,
Rob

Bee Pee · 03-08-2016, 02:39 AM

Hi Rob,

I didn't scan them TBH so can't verify the part numbers you quote. Looking at the markings embossed on your calipers they look the same as mine.

Not really - I got OEM MP BBK upgrade for less than 1/2 the cost.

30mm rotor size change is a huge difference. If this is under $1.5k new rotors included to get 30mm more, that's a steal.

And if u consider selling those old 340mm calipers out to 228 owners, then it might even be less than $1k. Total steal

for me (haven't yet installed, though)

$700 for used calipers, pads, and clips (same vendor as Bee Pee)
$600 for new 370mm rotors (blank face, not drilled)

well under $1.5k...

so those are the stock m sport calipers ?[/QUOTE]

To confirm you fit the larger Mperf 370mm rotors on the front stock M235i caliper without issue?

No.

Bee pee fitted F3X M sport calipers with the 370 rotors. F2X calipers won't work on 370 rotors I believe

rwalker · 04-02-2017, 07:13 AM

F2X front calipers will not work on 370mm rotors. You need front calipers from the F8X, which are the same as the M Performance calipers for the F3X.

Pika - 100% correct

Dylan86 · 04-04-2017, 05:14 PM

Any place online to grab the F3x M-Sport Calipers new, without getting a$$ r@ped? If there were any on the classifieds I'd scoop them up, but not having much luck lately. Missed out on Rob's set...

dukeapenguin · 04-05-2017, 08:24 PM

After research and test on my 235 and friends 228 I don't think there is a real improvement between 340 kit or 370 kit.

Only improvement is 30mm diameter which make a longer torque distance.

The weak point of this break sets I believe is disk, everybody changed pads but the fixed solid disk really making some issue when it get heated.

Get a floated disk, thats make the new world.
