Third Brake Light

Objective: 
Had another bit of time with the car. Trying to continue scratching items of the list I posted last time, today was to install the new 3rd brake light.

Before actually doing that, I took a look at the suspension. After installing the new shock last time, I had to put the car down to move it to a different garage floor as mine was being washed. So I looked and the right rear is still lower. Turns out the problem is not the shock. Phil from Aries did say it was strange to be a failing shock as they are usually bullet-proof as long as they don't do full-course. He was right. The problem is the spring that seems to not hold the weight as well as on the other side.

Having both spring adjusters set at the same height, the right side is 1cm lower than the left side. Tightened the right side enough to eliminate the difference when measuring from the lower chassis beams to the floor. I'll have to see with Phil if I should replace the spring or this is normal/acceptable.

Then the brake light. The theory was easy... Splice a cable into the connection from one of the rear brake lights, hold the cable on the rollbar, connect to the light and hold it in place. Did just that, with lots of testing in between to be sure the light worked when the peddle was pressed. Used black electrical tape to wrap around the rollbar holding (and hiding) the cable. That worked well.

The problem was holding the rear light in place. it has a kind of a steam from where the cable exits and, since it is not flat, it doesn't sit well on the rollbar. Ended up "fabricating" a U-shaped support with a bit of shielded copper cable wrapped in black tape to put behind the light. Then held the light in place with cable ties. It looks really sloppy/temporary. I have to lose some time fabricating a proper support in aluminium to bolt the light to. Even if then the support gets just cable-tied to the rollbar. But for now that is enough and I'll feel safer on the next track day with this added light.

In the end, this is how it looks like:
