E92 Alpina D3 brake upgrade

[Rossco196x]

Hi I've got a 2009 MY Alpina Bi Turbo. They used the the 330d running gear and brakes but still only used the single piston calliper to squeeze the cheese hence i would like to upgrade to a better set of 4 pot M sport type callipers for looks and better braking. I don't want to go down the M3 route as i would like to re use the original hubs and running gear hence is there a simple open to just bolt on some better callipers .

Thanks

The internet says F30 front Brembos fit. You’ll need the F30 discs too. I don’t know what size wheels are needed to clear them. The E9x 335i/d used 348mm discs. This were fitted to later 330ds. If you have these already I’m not sure the Brembos will be much of an upgrade apart from appearance.

If the F3x brakes fit, you need to suss out of it’s the 340mm discs or 370mm discs as the callipers are different sizes & marked on the rear which discs they’re for

On the F3x cars, ALL F3X 18” alloys fit over the Brembo M Performance brakes (so 345mm rears, 370mm fronts). 17s will not fit, at all

Offsets c30-40

Hi Thanks for the update, my budget is circa £300 + the cost of new pads for the callipers second hand as i've seen some on flea bay that are four pots.

I was hoping to keep this Plug and play using the current set of disc's which i think are circa 330mm x 24mm

Wheels are 19 inch

Personally I'd keep saving until you can afford the full set up and ideally; have the calipers refurbed via Bigg Red or similar...

Have you tried more aggressive discs/pads & braided lines; or are you after the looks ideally?

[Rossco196x]

I've recently changed the pads and upgraded to MTEC drilled and vented but the brakes squeal despite numerous applications of copper slip and cleaning everything

I assume it probably the callipers that are causing the squeal hence i'd rather upgrade then rebuild whats there.

Mtec brakes are utter ste; stay away from them. They're 'cut' Mintex discs; so cheap as they come!

Go for ATE discs, ATE Ceramic pads and HEL braided lines. ATE are OEM, the Ceramic pads are superb with great bite from cold and little to no dust & the HEL lines will give you superb pedal feel... A fluid flush & refill with decent brake fluid will finish the system off nicely

[Rossco196x]

Interesting ref the comment on Mtec. I've heard some people recommend them but i fear your probably spot on. Will have a think and look at what other options i have as the standard brakes look dismal.

Thanks for taking the time to reply

No worries; I've fallen foul of the Mtec brakes myself; so know through experience how crap they are!

For discs I tend to stick with OEM now (ATE, Jurid, Textar, TRW) and Brembo. As for pads, the aforementioned ATE Ceramic pads are right up there, along with Ferodo DS2500 pads and then OEM BMW pads... Jurid & Textar are OEM makers too; but the 'aftermarket' pads are a different compund to what they use for the BMW pads, so tend to be a bit dustier. Standard Brembo pads I avoid as they're very dusty and can feel quite 'soft' too

I ran ATE blank and ATE PowerDiscs with their Ceramic pads on all my E39s inc my last 2 Japanese import E39s; as well as a previous F01 730D

You'll find them at good prices on Autodoc, just give them a week or 2 to be delivered

[Rossco196x]

I've used Auto Doc but only when i'm 100% sure on fitment as there not that easy to return wrong items to.

I've used Textar and Brembo on my other cars , the Alpina is my daily driver at the moment but picked up a cheap TT 225 yesterday but now looking for a clutch for that for some reason..........

[helix402]

These bolt straight on:

335i/335d/late 330d (maybe late 330i):

348mm



Discs pictured are E89 Z4 35is.

As mentioned the internet says F3x 340mm Brembos bolt on with the F3x discs. I haven’t tried it.

If your budget is only 300 quid, I would go for some more aggressive pads if it is about braking performance.

[helix402]

Shame you missed my old brakes (including nearly new gen BMW discs and pads):



I think you’ll struggle to get the Brembo conversion for £200+pads.

[Rossco196x]

Thanks Helix

Looks like were going to need a bigger budget then. Will look later on line to see what other options there are

Thanks

Yup; as said above

For now; stick with decent OEM spec discs & pads. They'll make a lot of difference compared to the Mtec stuff you've got fitted

Get the part numbers off RealOEM and cross reference with Autodoc, you'll get the right parts then

Endless pads if you save up!
