Any E46 135i Brembo Calipers, rebuilt with aluminum pistons

I have these brakes that I planned to use myself, but I'm not in a place financially to finish building the kit.
What I have: (can choose to take some or all parts)

(2) front 135i calipers, rebuilt with stop tech aluminum pistons(oem ones have ceramic caps that crumble)

A set of lightly used OEM 135i brake pads.

135i caliper brackets, Unmodified, but I have a plan to modify the stock bracket for fitment on e46.

(2) e46 m3 rotor blanks

Set of hardbrakes.com titanium brake pad heat shields

I am into these parts about $1200 so far, but feel free to talk to me about the kit or what is needs to complete it.

Just for clarification here- this kit is based off the kit available from ECS, however it is rebuilt with StopTech aluminum pistons, high heat dust boots and seals. These parts are $400, plus the titanium het shields are $135... This kit is overkill and incomplete for a street use car- but if you track your car, this setup is much more usable than that kit since the performance rotors, and ceramic tipped pistons are prone to failure under high performance driving use.

New price: $1,000

Is this kit for e46 non m. Or m only?

It will fit with the unmodified bracket on a non-m, just the brake pad will be a few mm off (I have ran it this way without a problem lol) If you want it to fit perfect, you have to do what ECS did to align the caliper exactly how it should be. And they just use the M rotors because it is the right size. These are basically 6-piston brembo's branded for BMW, not a bad deal for anyone looking to upgrade. I can stop on a dime AND that is with the crappy stock pads!

good luck chad. what size are the ti heat shields? 0.5mm or 1.0mm?

The heat shields are 1.0mm

Glad you're happy with the setup, the alignment isn't off by much- in fact the bracket only needs to be shaved by 6.5mm in one dimension to be perfect. I spent a bit of time measuring and planning this out.
Also, the ECS kit doesn't use m3 rotors, rather they use the performance rotors for the 330 that maintains all the dimensions of a stock rotor, the m3 rotors are also the same dimensions with the exception that the rotor thickness is slightly greater at 28mm vs 25mm.

Just realize that you wrote "M rotors" and not "M3 rotors" ... My bad, well I'll leave my mishap up for others to see as it still offers a little nugget of knowledge about 330 vs m3 rotor specs.

This is a hell of a deal. Too bad you can't hold onto them.

pictures?

ill be making the brackets, and have decided to keep them for as long as it takes for me to make, fit, test the brackets... then, who knows... i will see at that time if I can live without them, or not... I don't believe I will be tracking my car for a couple years due to financial constraints, so I may still sell when done.

Are these still available ?

Not currently- I've decided to make a bit more of a project out of them yet... I am selling the pistons/seals/boots to a friend, and will be making my own pistons, as well as stripping and powdercoating them as they show a little abuse... Currently planning to use a high heat powdercoating so they will withstand track abuse...
I may try to start finding/rebuilding and reselling these soon, so keep in touch if you're Interested.

I've got a top secret update... I've been playing with the machines at my uncles shop...


I made replacement pistons for these calipers out of stainless steel, and will be producing the mounting brackets very soon as well.

Are you going to start selling the pistons?

What would it be worth to you if I send you a set of say..... some brackets that are already made for these that you can 'look at' haha

Maybe.... Lol. I have a set that will be track tested soon, and a second set ill be rebuilding my calipers with... If I have interest, ill have a batch made. I have a 5 set minimum order to fulfill in order to have them run at the machine shop.

Thanks, but I have all the geometries worked out already, and even have a solidworks plan of the bracket.
