I (finally) did a thing

A very small thing, but nonetheless, a thing. Fitted cambolts to the 86's front suspension. A nice easy way to get a little more camber and extend the life of the PS4s without going to the expense of doing a proper job. We’ll see if they survive OK at the track: if not, I guess it’s camber plates.

This fulfills !!!error: Indecipherable SUB-paragraph formatting!!! a few weeks ago to do at least one goddamn piece of work on a car before the holiday season ended.

As predicted, I wound up in trouble due to needing a tool I didn’t have and couldn’t easily get in the holiday season (“holiday season” in NZ = “total and utter shutdown of the entire country for 2 weeks”). Seriously, Whiteline, a 20mm   nut on a bolt over-length enough to need a long socket? What’s wrong with 19mm or 21mm like normal people use?

Fortunately, a little creative engineering using a 13/16" spark plug socket and some offcuts of 0.5mm aluminum let me torque it up just nicely:

Oddly enough, according to my highly sophisticated wheel alignment jig, it wound up at zero toe without needing adjustment. So either:

The centre of rotation of the hub on the strut bolts is level with the steering arm - possible, and I’ve noticed before some nice detail engineering on these to make modification easier. But lets face it, unlikely

It was previously misaligned with significant toe-out: also possible if improbable, though it used to track fine - haven’t taken it for a run yet and seen if that’s changed.

I’ve completely ballsed up the toe measurement - lets face it, this is the most likely reason

Either way, it’s going in for a proper alignment ASAP - this check was just to see it through till that happens.

Cloudy today so we didn’t see the forecast red sunset. The worst of it’s south of me though:

I have had the same Whiteline issue but ( fortunately) have a spanner collection issue so a 20mm ring spanner is not a problem. Finding it in the collection is another matter!

A spanner was no problem, I’ve got one of those (not to mention a selection of Crescents). The issue was finding something to apply a torque wrench to. For some things I’m happy with “just grunt it up”, but for high tensile bolts that hold the suspension together,  I like to know they’re right...

Ah yeah... torques. I know what 4 to 6 torques and 40 torques ‘ feel’ like but the rest is just a rough conversion between Newton metres  and Ham Fisted Gorilla Units.

Are your levels or whatever you are using as the alignment tool pushing against the tire bulge next to the contact patch, that can bugger up your measurements.

Likewise. Not to mention the bolts in question are M14 12.9 grade, and the set point is right up the top of what my 1/2” torque wrench will do. My arm isn’t well enough calibrated to tell the difference between “fuck that’s right ” and “holy fuck that’s tight”.

No, they’re sitting on a couple of lengths of 4x2 to keep them  above that.
