Check how long the hub spigot is that wheels locate on sometimes it longer than 10mm, if it is you need thicker spacers to allow them to sit flush, I think on mine 12mm is as thin as it will take on front and 15mm on rear.

Yeah we tried 5 mm spacers and then they only just touched the spoke on the inside...so 10mm should be enough.

Or maybe to go safe i should go 12mm?

I thought going 10mm front and 10mm rear,just to not uoset the geometry of the setup.

Should i go 12mm front and 15mm rear?
I have 8,5j on rear with 255 wide tyres...think 15mm will be to much!

If 10mm will go onto hub ok then use those, ive got 12mm front and 5mm rear at moment but have run 15mm on rear, depending on tyres you can get scrubbing though so fit as small as you can for caliper clearance.

I don't think you will get 10mm on rear as hub spigot is longer than that on ones I've seen, 15mm is thinnest I've been able to run on rear of my 130's and 135's

After laying up a potential m135i caliper/wheel combo it seems it might only clear with some small spacers. From the flanges the caliper bolts to, to the outside of the caliper measures approximately 124mm. From the split of the caliper to the outside measures 81mm. A safe clearance would be something like 3mm? Are the 6 pots any narrower in that respect? Smaller pistons (smaller, shorter bores) and the bridges might mean they're slimmer?

Might help people contemplating this upgrade!

I think the 135i/BMWP 6pots are a bit slimmer from memory and i know discs on those are only 26mm thick as opposed to 30mm on M135, also 6pot pads are approx 1mm thinner on 6pots as well so it all helps with clearance i guess, on my car the stock msport 208 wheels clear with M135i calipers without any spacers, its close but they do go on, on my 264 wheels they need spacers due to fouling back of spokes, cant remember if 5mm was enough but i do know that the hub spigot wasnt big enough to use a 5mm slip on safely as not enough left sticking out to locate the stock wheels due to taper on wheel bores.

If i get chance i might make up a fitting template for the M135 caliper setup that people can use to try on the wheels before buying/fitting calipers.

Disc and pads thinner too huh.. I hope I dont have to resort to the 6 pots after all the work for the 4 pots. But good to know it might be an alternative!

M135i 340 & 142 7/7.5" or Type III 17" are all a no go due rubbing. Type III with oem 130i setup also no go.

I will try to put the m135i brakes on my car this Saturday with 10mm spacers...

Fingers crossed,and will ofcourse post a message here if it fits!

Legends,

I'm about to acquire some M135i brakes and will be fitting the fronts ASAP to my E87 130i. I've trawled this thread but couldn't find an answer to my Q.

While I'm changing the set up, I thought I may as well up-rate the fluid and fit some braided lines. What I need to know is: should I buy E87 or F20 braided lines to work with this set up?

Also, any recommendations for low-dust pads that see 95% daily duties and the occasional (very) spirited weekend blast on back roads?

Thanks in advance,

Alex

Use E87 hoses, brake fluid for road use just use good quality brand Dot4 spec.

Pads wise I find the original BMW very good allrounder with reasonable levels of dust etc, any good quality OE spec like MIntex/Ferodo etc should be fine also.

so...

M135i brakes fitted to my car !! :D

Used 10mm spacers to clear wheel spokes... it cleared them now with 1,5mm in between :shock: :shock:
Image20180519_102744 by m tt, on Flickr

So only just,but it fots...so really happy!


Had to put 12 mm on the rear cause 10mm was not enough to go around the centre lip om the hub...cause the lip is 12mm(or 11 and a bit)
now i get some rubbing on speedbumbs,so have to roll wheel arches i guess....its not much,and only when going at speed! so a little adjustment on arches should be sufficient!

So: when upgrading m135i front brakes on a e81 130i with slyle 313 wheels 7,5j ,you will need at least 10mm spacers to clear the wheel spokes!!!

All in all happy chappy :lol:


car drives and brakes incredible now!! wow what a stopping power and how well do they feel on the brake pedal!!

With the wider track of the spacers,car feels like on train track...fantasticly stable at high speeds,and steady thru corners...

Holy batman that looks tight! :shock: :shock: :shock:

Anyone got any tips for stuck discs? They seem rusted on the hubs. Front wheels had been on for around 5 years and where a struggle to get off as well :|
