dual caliper settup

[deek10sn]

First does anyone have one for sale? I have fab skills for custom brackets, so besides buying Wildwood single pots what other rear calipers have you guys used? The cable settup has to go!!! This is for an e36m.

Thanks
Derek

I know Rustyfriend just said he's in the process of making a bracket for a second stock caliper. I will either be doing the same or I may use a front from an e21 since I have a couple sets of those laying around.

[deek10sn]

Wasn't sure if there were any 1 piece alternatives people were pulling from other makes/brands of cars. Or maybe smaller than a rear M3 caliper?

Hi Derek. Suck kit does exist. ;-) Bolt-on.

There are a few threads on BFc about those kits. One for e36 M3, one for e36 and one for e30. No cutting. No drilling.

OP is looking for an option other than buying wilwood calipers.

Myself, audioscience rustfriend and many others are looking for a cheaper more commonly available caliper option such as an OEM caliper.

[deek10sn]

Lee, have always trusted your info and parts/ thanks for all the tech you have provided to performance BMW parts! With that being said, was seen if say is there an option on any other make or model of car/truck that is a 1pc that anyone else has used (240sx/fox body/supra) anything?....or just man up and rock a Wilwood kit (already run Wilwood bbk lol)

Thanks guys

[sdipompo]

if you want to be cheap just weld 2 ears to the hub. shouldn't take me then 20 minutes

[Piner]

honestly the willwood calipers arent that much, you can find them new for 300 for a pair on ebay with pads. great deal for what you are getting. I love mine, they lock the rear wheels up fantastically plus they look cool.

[Massive Lee]

The problem with using an OEM sliding caliper is the play which comes with the sliding mechanism. The tiniest play will show up greater at the handle. How heavy is an OEM steel caliper? Most likely heavier than the 3lbs Dynapro. A used caliper needs refurnbishing while a new caliper is... new. Not to mention the great selection of compounds and brands for the Dynapro. That being said, I am not pushing the kit itself in its final execution, but the thinking behind it. ;-)

One thing is for sure, having a parallel hydraulic system is night and day. You can feather the main brakes to transfer weight to the front wheels, and then modulate the hydro handbrake totally independently to slide the back end. Can't do that with an hydraulic handbrake plumbed into the main system.

i just wish i could keep the stock ebrake on my 328is with the massive kit. i live in the texas hill country and everywhere i park is on an incline.

Agreed, I searched your sight and only came up with the e30 version, can you post a link for you e36 m offering.

[jakermac]

Lee,

I wish you had a bracket for the OEM non-M rotor (280mm x 10mm) for the extra caliper. I'd use that with a single piston sliding or dual piston 1.5lb Wilwood caliper as my primary caliper and ditch the OEM caliper for a nice lightweight autocross setup. Then I'd get Coleman to make me something nice and light for a rotor and sketch up a nice lightweight aluminum hat to mount it on.

Can you say "drop 15lbs of combined unsprung weight off the rear axle"?

It is not technically possible to bolt an adapter with a 280mm disc using the smaller 160mm handbrake shoes.

Calipers used are Wilwood Dynapro 120-9703 - I suggest Wilwood's H compound pads for the highest grip.
Jegs and others eShops offer the calipers for under $150.00 each

And it all started 3 years go after 6 months of design and test fitting.

is there ANYWAY at all to have an independent caliper and retain the stock ebrake?

or...... the k-sport hydro ebrake has a provision, if i recall that can lock it in place, would this work for a makeshift parking brake?

[Piner]

^ could work a bit but I would still leave it in gear as a fail safe. I don't know why you dont trust leaving it in gear.

Park on a hill stay in the car dont pull up the e brake and put it in 2nd and let off the brake and the clutch. you wont go anywhere.

i do this anyway. parking brake is never good enough here. but i always use the parking brake too.

plus, how do you deal with state inspection?

[Massive Lee]

Hi guys

The hydro handbrake kit was designed for dedicated drift cars. Guys wanting more performance and modulation from their handbrake, and especially legal for drift associations requiring independent hydraulic systems between main and handbrake channels. It is a competition-only part. You can't have a competition part on a street-driven vehicle unless you're willing to give away something. It's like fitting a coil-over suspension and expecting Cadillac-plush softness and quietness. Or fiting aluminum suspension bushings yet not wanting vibrations, and so on... ;-)

Agreed! And Lee thanks for the extra info in your earlier post! I understand the r&d you put into your products as well as the fab and machining it takes to produce said products. Thanks

Lee: Whats the pricing on the non-M bracket kit? And ballpark what would a set of calipers run?

[Piner]

Well lucky me Florida doesnt have state inspections of any kind :) . We get away with a lot of crazy shit.

i tested your "put it in 2nd theory", yeah, in my driveway, it doesnt work. first held okay, but 2nd wasnt having any of it. i wouldnt even trust first by itself.

[Piner]

well then your best bet is to run an inline hydro setup or make a bracket you can weld on to the rear control arms to mount calipers. My factory ebrake didnt work at all so I didn't miss it when I went to the massive setup.

[Gmfwd]

I built a fixture to setup wilwoods on a non-M e36 and retain stock parking brake. It is weld on however. I like it because I can use the better calipers but still run 15" wheels if need be. I can get pics if you want.

And I also ran dual stock calipers for a season and it sucked. Lee is 100% spot on with the floating caliper comment. Stock calipers really need a lot of throw, but dont make much force due to small piston area. The willwoods have a ton more area and similar throw if not less.

that would be great if you could!!! i recently donated my old mig welder i didnt have a connection for to the shop i hang out at. i havent welded in years, but this might be a great project.

details please!

Okay. So there's specs on wilwoods site with formulas explaining where to mount the caliper depending on rotor diameter, thickness, etc. I used those to design and machine this spacer/fixture. You clamp it to the rotor, and it ensures that your brake bracket is at the proper radius, the caliper is tangent to the outer edge of the rotor, and it is squared up in all other directions. Then you cut a bracket that you like, bolt it to the fixture, and weld it up.

I chose to cut down my backing plate, leaving it just large enough to support the ebrake shoes. You can just cut an area for the new caliper if you please.

Bolt your bracket on and clamp it to the rotor.

Poop weld it on. You will have to leave a gap on the back side where the abs sensor is. I also added a gusset in the back to reduce weld warping.

Replace wheel bearing, upper and lower balljoints(good upgrade) and trailing arm bushings while you have all this crap apart

Done. Stock ebrake, stock foot brake, baller e-brake, and 15" wheels.

I can rent the spacer out if anyone needs it. Its just going to sit around my workbench unless I need to do another e36

[jc e46 m3]

Sorry to revive an old thread and not trying to thread jack but does anyone know or make a dual caliper bracket for an e46 M3? Maybe someone that could make it or point me in the right direction any help would be appreciated.

[protomor]

Find a welder friend. That's really all you have to do. :)

Lol ok I was just checking to see maybe someone had them pre-made or something thanks for the info

Have you checked Massive Brakes?

Ya but they only have a kit for the e30 [emoji17]

He definitely makes a kit for e36. And could probably do one for an e46 if he hasn't already

Oh my bad I don't get on Facebook much thanks for the info

Great work Gmfwd (https://www.bimmerforums.com/forum/member.php?344377-Gmfwd) ! I PM you, but i am not sure if you received my message. Do you still have the scheme for the spacer and the welded plate ? If you could share them it would be awesome !

i posted in this thread but never seen the outcome. def interested in a bracket for this.
