E46 locating components 

Not sure where to place the fire bottle (it’s tiny!), battery and cool shirt system(yet tbd). 

Thinking the cooler will go where the passenger seat mounts. 
Battery and fire bottle have wires & tubing to run. Along the sill would be cleaner than runs along the tunnel. Some pictures for consideration. 


Helmet ideas for the next helmet

My last helmet was painted – by me – and I enjoyed the process.  The design was nice and could have been better executed but I was pleased with the result.  Unfortunately, the helmet expired (SA2005) and the new has a 10yr life span (SA2015); it will have to look even better than the last. 

With the car build moving so slowly and ready to accelerate hard with short notice, outsourcing the helmet paint is looking more attractive. 

There is a large collection of helmet images saved to my personal collection over the years as considerations or inspiration: some for colors and others for designs that I find attractive.

These images illustrate my expired helmet and short list of favorites from the collection.

Filler tasks 

Exhaust studs. The factory stud length is 30mm and I’m planning to use aftermarket headers. There is some forum discussion about insufficient length with some headers but not enough detail for solid decision making. 

Found “premium” studs left over from the e36 that are 42mm. 

For solid data, the header source was consulted about this and learned the factory studs will be long enough but just barely. 

That cemented the plan forward: use the longer studs to ensure safety margin. It took awhile to remove the old studs and the new will likely be as fun to install. 

Filled more of the day with brake line research.  BMWs use a bubble flare on their brake lines which I needed to know.  The original hardlines did not survive and replacements are needed but new lines are not pre-bent.  In case of error bending the lines, I may need to make different lengths and will require flaring the ends.  This post at rtsauto.com was helpful.
