Yes. M42 cams are hollow.

[DCColegrove]

Did you downgauge the wiring?

Yes.... Basically it's an ultra fine strand and it's capacity is about 75% higher than standard primary wire. the insulating sheath is teflon and I think it's only about 2 mil thick..


It's a bitch to work with though... You gotta' be really good with a soldering iron because if it gets too hot and you feed it too much it will suck solder way the hell down the wire (makes for a break in the connection down the road).

[blunttech]

Yes ABS isn't the stiffest shit in the world needed some side supports

M42 cams are hollow?

What factory shop do you work at anyway...

are m42 cams indeed solid?? honest question because i dont know. all i know is the m50/s52 variants

[DCColegrove]

Yes. M42 cams are hollow.

I'm jerking the Nozzle's chain.


(Thanks Farbin... Nozzle... I dig it)

No. they are thick walled though.

I do have some sets of composite cams for M42s that are really light... Not in the car though.

yes they are hollow- I work at a BMW dealer here, and a couple years ago, I changed one that a buddy of mine cracked in half installing it-- so F**K your master mechanic self. I am not straight out lying like you!

[Lof8]

Alloy rivets, closed cell seat foam, and lightweight wiring? That will net you about 200 wasted hours of your life and 2 lbs of weight savings. I bet with all the chassis bracing, this thing weighs more than stock.

[DCColegrove]

Jesus... All I have are these really bad cell phone shots....

[BeirBrennerE30]

FYI you are not supposed to solder that wire... or really any wire in a high vibration environment. Crimp connectors are your friend

Go some place else will you... Before I loose my temper and call you a waffleswaffleswaffleswaffles.

It's a trade off... Conduction vs physical joint strength.

The amount of time spent is insane unless or course you become obsessed and get some kind of perverse pleasure from the process...

My friend whom I've worked with on this stuff for years is possibly the worst OCD case I've ever seen... He makes a very good living at it though...

My DD only has a front and rear brace to the tune of about + 3kg.

[einstein57]

Okay... I did indeed miss calculate the kerb weight... I think my conversion from kg to lbs was defective (I'm no math wizard)... @2255

At any rate....

Rather than me telling you all how (that would be silly of me under the circumstances wouldn't it)...

Here is a project for one of you:

First you are going to need a clean stock e30 and a large space to work in (Airport hangars work well for this). You will also need a bunch of money and time (get together and pool your resources).

Completely disassemble the car (completely... you have probably seen pictures of this).

Weigh every single component.

Re-fabricate, substitute or throw away items PRN. ABS, Aluminum, titanium, Teflon and (oddly enough) hobby shops are your friends here...

Come on dan. For someone who keeps us updated step by step on the fabrication of a brace i'd expect you to keep a detailed and photographed log of everything you've ever done to the car with before and after weights. Don't tell me i'm the only one who does this.

[DCColegrove]

This was maybe three months after I bought it... I think it got its running gear pulled out this day

I have my notes...
