Dave: unsure on the Kelsey controller, and to be honest i havnt had a chance to look at it. Also isnt the Enduro on the 8th?
I probably wont be driving or crew, but probably going to be Media.
Anyway, after that slight excursus, back to trig and strut angles.
Last night i sat down with a pen and paper and a scientific calculator and made some pretty diagrams with numbers on them. I made some pretty bodgy assumptions, such as the LCA being horizontal, and when the LCA is horizontal the stock camber is 0deg, neither of which are particularly true. But on the other hand it does let me treat it all as a right angle triangle.
If anyone is interested in the maths its basically “Given strut angle (90*-AoI) and LCA length, solve for other sides”, then “Given shock length (from part A), and LCA length, solve for strut angle” then subtract strut angle from AoI to give effective camber.
Now with my bodgy assumptions i came to the rough conclusion that i would have about 0.9 deg negative camber with the MX83 suspension bits.
And then i woke up at a ridiculous time this morning, given that my wife is on an ambulance shift and had to be there by 7, and went out to the garage to test it. I basically dropped out the strut quickly, and then put the strut top onto the MX83 strut and bolted that in. Now i buggered the thread on the already stuffed steering arm at UPullIt getting it off so i had to just let it sit together to see if it worked. Onwards and upwards with the jack.
I took a measurement of the hub to guard distance on my Cressida for a
rough guide, and jacked it up to that height (350mm).

Breaking out the inclinometer i measured the angle:

1.3deg negative camber, not bad at all for some bodgy trig. Now the 0.4deg difference im putting down to the stock camber not being 0 when the LCAs are parallel to the ground.
I then had a bit of time on my hands and went and got the spare out of the Cressida to just have a quick test fit:

Looks about 1.3neg too:

I cant jack it up any higher, because i havnt removed anything from the other side, including the swaybar, so if i try to jack it up higher the swaybar just binds up the chassis and lifts the entire chassis off the stands. Ooops.
Thats about it for now, i might get a chance to fiddle later if i go home early from work, as the stupid workmen are drilling again and i cant hear myself think.
