S54 swap questions and concerns

I see that. nice!

so, two of those is cheaper than 1 stock 325ix MC. :|

I'm planning on doing a BBK, probably massive's. with the exchange rate it's like a 25% discount. :)

was curious about the pricing of his bracket/MC setup. Would be really cool if those masters had dual ports because I need a 2nd one for the MK60 DSC pressure sensors..

Massive lists most of their current products on Facebook lol

Tilton 76 series MCs have dual outputs. They're a little more expensive than the 75 series.

is massive's pedal bracket thing available? it's not on their site.

I want to at least try the booster delete alone, but not with the rest of the brakes stock. I'm thinking something like above would be much better though.

It's not listed on his site. Email him. You have to procure the balance bar and MC's, and you reuse the stock clutch pedal by trimming it up a bit. You do get a nicely CNC'd brake pedal. Might want a remote reservoir as well.

I'm sure you know, but I have the booster delete with the e46 m3/e39 540i brakes and while it is decent, it's not great. I have Ferrodo pads in the front and stock pads in the rear, maybe I need to adjust the bias more or get some more aggressive pads (PFC 08 or somthing?). I also had a pretty disconcerting issue with the pedal rod coming out of adjustment, so I think I'm going to dis-assemble and re-assemble this weekend to ease my mind about it. The dual MC's would certainly be an upgrade over my setup, but the extra cost is pretty substantial.

What size MC are you using and what are the piston diameters in those calipers? A more aggressive pad should definitely help.

I was going to use E36 M3 front calipers (60mm) and M roadster/coupe rear calipers (40mm, same as E36 M3) and they only require a theoretical 100lbs input force at the pedal for 1.0g deceleration using a 3/4" MC, 6:1 pedal ratio, and aggressive street pad CoF. 75lbs-100lbs is the target according to literature referred to in the following, very useful spreadsheet found here that I used to back up my calcs (FredK shared this with me, who happens to have Massive Lee's pedal setup that I shared):

Using a 5/8" MC is about 70lbs. I'd choose the 3/4" because I personally wouldn't want a super long throw, and sensitive brake pedal, which can be attributed to "mushy" feeling brakes.

Let us know what we can do to help. We now carry the wilwood pedals and master cylinders and can make a package deal with our bracket.

I've already PM'd you guys about pricing. Great deal for sure!

Can you actually provide some more pictures of the setup in this thread?

if only you had a RHD pedal box option

[garagistic]

Right.
Garagistic bracket with wilwood/tilton pedals:



I'm leaning toward garagistic bracket setup as of now..

Nice that the 2002 booster fits! Must be tiny. I understand the lure of simplicity to retaining vacuum assist, but is it better? Or, just cheaper and easier than going with a well thought out balance bar manual setup (garagistic, massive, etc)?

Just a little more work, which there already is plenty of in the entire swap....sorry, this is just my brain splurging on here to help me decide on which route to take ;)

Keep it up!!

Cheaper, yes Easier yes, I say this cause after just having the folk modified I'll be able to just bolt everything up including stock mc. Is it better then going boosterless, yes and no, if ur talking about the legit boosterless kits out there and combine it with a nice BBK setup would be perfect, but that's going to cost u a few pretty golden penny's compared to going with a booster setup.

[gills]

It's better than the booster delete with the stock master cylinder, it is not better than dual tilton/wilwood/whatever master cyls. I think that'll be what I work toward in the future, my current brake setup is still not confidence inspiring. The dual mc's is the way to go IMO

Right.

The search is over, finally found a 2002 booster...yay! Although it's not a great option but it's better then going boosterless.

This is the best option without having to modify the manifold, fits perfectly, no drilling no cutting no spacing nada, but u do have to modify the folk to fit the pedal.

[Jb325is]

Yeah, that looks annoying. I really think the Z3M harness is a better option for sure, but its hard to find one used and they are a bit pricey new

[DrLeadFoot]

Sub'd. Need to start doing my homework on this!
